PTOL-90A (Rev. 04/07) UNITED STATES PATENT AND TRADEMARK OFFICE __________ BEFORE THE BOARD OF PATENT APPEALS AND INTERFERENCES __________ Ex parte EDWARD C. FACUNDUS and DANIAL C. CELESKI __________ Appeal 2010-011217 Application 10/966,903 Technology Center 3700 __________ Before TONI R. SCHEINER, FRANCISCO C. PRATS, and STEPHEN WALSH, Administrative Patent Judges. SCHEINER, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134 involving claims relating to an apparatus for use in stomach reduction surgery. The Examiner has rejected the claims as obvious. We have jurisdiction under 35 U.S.C. § 6(b). We reverse. STATEMENT OF THE CASE The Specification discloses “a multifunction instrument used in gastric bypass surgical procedures” (Spec. 1:7-8). The Specification Appeal 2010-011217 Application 10/966,903 2 discloses that the “tool integrates a template balloon for forming and sizing a small gastric pouch with a gastric sump tube having one or more lumens” (id. at 1:8-10). The Specification discloses that the lumens are “adapted for the functions of draining and collapsing the stomach, …filling the balloon with air or a fluid to define a gastric pouch and filling the completed [gastric] pouch with air… in order to determine integrity of suture and staple lines and to test the pouch for leakage” (id. at 1:10-14). Claims 1-24 are on appeal. Claim 1 is representative and reads as follows: 1. A combined template, leak and integrity testing apparatus for sizing and forming a gastric pouch and testing integrity of a newly-formed gastric pouch during stomach reduction surgery comprising: a gastric tube selectively sealable at a proximal end thereof, said gastric tube configured to extend from within a stomach of a patient at a distal end and out through a patient’s mouth at a proximal end, said distal end of said gastric tube having a plurality of openings, a balloon attached to said gastric tube proximate to said distal end of said gastric tube, said balloon inflatable to serve as a template for forming a gastric pouch, a port at said proximal end of said tube for receiving an inflating medium for said balloon, and a balloon tube communicating between said port and said balloon, a suction coupling mounted to a proximal end of said gastric tube, said suction coupling and said gastric tube configured to communicate with at least some of said openings to an interior of a stomach of a patient, a pressure tube configured to be coupled to a pressure-developing device and respective pressure monitor at said proximal end of said gastric tube, said pressure tube communicating with at least one of said openings in said distal end of said gastric tube, whereby said balloon is inflated and a source of suction is applied to a stomach to withdraw contents therefrom and deflate the stomach around an inflated said balloon to define size of a gastric pouch, and after formation of a gastric pouch is completed, pressure is applied to an inside of the gastric Appeal 2010-011217 Application 10/966,903 3 pouch by said pressure-developing device to pressurize a newly-formed gastric pouch so that integrity thereof may be determined. The claims stand rejected under 35 U.S.C. § 103(a) as follows: • Claims 1-3, 5, 7-10, 12 and 14 in view of Hakki1 and Stark;2 • Claims 4 and 11 in view of Hakki, Stark and Siegmund;3 • Claims 6 and 13 in view of Hakki, Stark and Greelis;4 • Claims 1-3 and 5 in view of Moss5 and Stark; • Claims 15-18, 23 and 24 in view of Freeman,6 Kraemer7 and Black;8 • Claims 19 and 21 Freeman, Kraemer, Black and Siegmund; • Claims 20 and 22 Freeman, Kraemer, Black, Siegmund and Greelis. I. The Examiner has rejected claims 1-3, 5, 7-10, 12 and 14 under 35 U.S.C. § 103(a) as being obvious in view of Hakki and Stark. The Examiner has also rejected, under 35 U.S.C. § 103(a), claims 4 and 11 in view of Hakki, Stark and Siegmund and claims 6 and 13 in view of Hakki, Stark and Greelis. Since the same issue is dispositive for all three rejections, we will consider them together. The Examiner finds that “Hakki discloses an apparatus capable of sizing a gastric pouch and testing integrity of a newly formed gastric pouch 1 Hakki, US 5,188,592, issued February 23, 1993 2 Stark et al., US 3,448,739, issued June 10, 1969 3 Siegmund, US 4,598,698, issued July, 08,1986 4 Greelis et al., US 5,336,183, issued August 09, 1994 5 Moss, US 4,642,092, issued February 10, 1987 6 Freeman, US 6,543,456 B1, issued April 08, 2003 7 Kraemer et al., US 2005/0080444 A1, published April 14, 2005 8 Black et al., US 6,245,083 B1, issued June 12, 2001 Appeal 2010-011217 Application 10/966,903 4 during stomach reduction surgery” (Answer 3). The Examiner finds that the Hakki apparatus comprises a gastric tube (10) having a proximal suction coupling and distal end openings which communicate via the gastric tube (id. at 3-4). The Examiner finds that the Hakki apparatus further comprises an inflatable “balloon (50) attached proximate to the distal end of the gastric tube which “serve[s] as a template for a… gastric pouch” and a balloon tube communicating between an inflation port and the balloon (id. at 3). The Examiner finds that the Hakki apparatus further comprises a pressure- developing device connected to a pressure tube that communicates with openings in the gastric tube (id. at 4). The Examiner finds that Stark discloses a pressure gauge coupled to a pressure-developing device to allow pressure monitoring of the organ or vessel pressurized by the pressure developing device (id.). The Examiner concludes that it would have been obvious to one skilled in the art to modify Hakki’s apparatus to further include a pressure gauge, as disclosed by Stark, “in order to be able to monitor pressure… to ensure the correct amount of suction and inflation is occurring” (id.). Appellants contend, among other things, that the cited references would not have made obvious the claim 1 apparatus with “a balloon inflatable to serve as a template for forming a gastric pouch,” as required by claim 1, because “the balloon of Hakki is far too small to be of any use… in forming a gastric pouch” (Appeal Br. 17). Appellants argue that the Hakki balloon “is only inflatable to a maximum diameter of between 3mm and 20 mm… [and] [i]t is well known in the art of gastric reduction surgery that stomach pouches are 3-4 times this size” (id. at 16). Appeal 2010-011217 Application 10/966,903 5 The Examiner responds that sizes of the balloon and the gastric pouch formed by the balloon are not claimed and “therefore the device must only be capable of sizing a gastric pouch of any size in order to meet this functional limitation” (Answer 10). The Examiner further responds that the apparatus and balloon of Hakki “is capable of being used to size a gastric pouch” (id. at 11). We agree with the Appellants that the Examiner has not adequately explained how the cited references would have made obvious the apparatus of claim 1 with “a balloon inflatable to serve as a template for forming a gastric pouch.” Hakki discloses a “multi-tubed catheter for physically dislodging and removing material from a lung by suction and simultaneously aerating the lung with oxygen” (Hakki, abstract). Hakki discloses that the “catheter comprises an oxygen tube for conveying oxygen into the lung, a suction tube adapted to remove material from the lung and an inflation tube for inflating a small balloon for separating the flow of oxygen from the suction” (id.). Hakki discloses that the “balloon… may be designed to have a maximum diameter of between 3.0 mm. and 20.0 mm” (id. at col. 7, ll. 17- 20). Hakki discloses that the “balloon 18 will generally be fully inflated with less than 10.0 cc. of a gas such as air” (id. at col. 7, ll. 20-21). The Specification discloses that in “gastric reductions, [the] capacity of the stomach is greatly reduced… from a capacity of about 800 cc to 1100cc… [to] about 15 ml to about 200 ml” i.e. about 15 cc to about 200 cc (Spec. 2:13-15). Since Hakki discloses balloons with a maximum capacity of less than 10 cc and the Specification discloses that a minimum gastric pouch size is about 15 cc, the Examiner has not adequately explained how a Appeal 2010-011217 Application 10/966,903 6 balloon that has a maximum volume less than the smallest acceptable size for a gastric pouch would be capable of sizing a gastric pouch. The Examiner’s reasoning that claim 1 does not specify the size of the balloon is not persuasive because claim 1 does specify that that the balloon must be capable of sizing a gastric pouch. Thus, we reverse the rejection of independent claim 1 and dependent claims 2, 3, 5, 7, and 8 as being obvious in view of Hakki and Stark. Independent claim 9 is directed to “a tubular surgical implement for use during a stomach reduction surgery to form and test a newly-formed gastric pouch” and is similar to claim 1 in requiring “a balloon of a size selected to define a size of a gastric pouch.” Thus, we also reverse the rejection of independent claim 9 and dependent claims 10, 12 and 14 as being obvious in view of Hakki and Stark. The Examiner has also rejected, under 35 U.S.C. § 103(a), dependent claims 4 and 11 in view of Hakki, Stark and Siegmund and claims 6 and 13 in view of Hakki, Stark and Greelis. For these rejections, the Examiner relies on Hakki and Stark, as discussed above, and the Examiner relies on Siegmund and Greelis to supply dependent claim limitations. Thus, we also reverse these rejections. II. The Examiner has rejected claims 1-3 and 5 under 35 U.S.C. § 103(a) as being obvious in view of Moss and Stark. The Examiner finds that “Moss discloses an apparatus capable of sizing a gastric pouch and testing integrity of a newly formed gastric pouch during stomach reduction surgery” (Answer 6). The Examiner finds that the Appeal 2010-011217 Application 10/966,903 7 Moss apparatus comprises a gastric tube (12) which comprises a suction coupling and distal openings which communicate via the gastric tube (id.). The Examiner finds that the Moss apparatus further comprises a balloon attached to the gastric tube and a balloon tube (26) communicating between an inflation port and the balloon (id.). The Examiner finds that the Moss apparatus further includes a feeding tube, “which can be considered a pressure-developing device” (id. at 7). The Examiner finds that Stark discloses a pressure gauge coupled to a pressure-developing device to allow pressure monitoring of the organ or vessel pressurized by the pressure developing device (id.). The Examiner concludes that it would have been obvious to one skilled in the art to modify the Moss apparatus to include a pressure gauge, as taught by Stark, “in order to be able to monitor pressure… to ensure the correct amount of suction and irrigation” (id.). The Examiner finds that the Moss balloon is “nearer to the proximal end of the device then the distal end” (id.). The Examiner concludes that one skilled in the art would have been motivated “to increase the length of the… tube proximal of the balloon in order to have more clearance outside of the body... [or] to be able to deliver the device to the stomach through a patient’s mouth” (id.). The Examiner reasons that this modification would have resulted in “a balloon that is proximate the distal end of the device” (id.). Appellants contend, among other things, that the cited references would not have made obvious the testing apparatus of claim 1 with a gastric tube and “a balloon attached to said gastric tube proximate to said distal end of said gastric tube,” as required by claim 1, because the Moss balloon is located closer to the proximal end (Appeal Br. 33). Appeal 2010-011217 Application 10/966,903 8 The Examiner responds that, with an increase in length at the proximal end to allow for more clearance, “the balloon can be considered positioned on the distal end of the gastric tube” (Appeal Br. 15). We agree with Appellants that the Examiner has not adequately explained how the cited references would have made obvious the testing apparatus of claim 1 with a gastric tube and “a balloon attached to said gastric tube proximate to said distal end of said gastric tube.” Moss discloses “an aspirating and feeding device for insertion into a patient’s body” (Moss, abstract). Figures 1 and 2 of Moss are shown below, respectively. Appeal 2010-011217 Application 10/966,903 9 Figure 1 is said to show “an elevational view of the gastrointestinal device” and Figure 2 is said to show the device “disposed within a patient’s body” (id. at col. 3, ll. 40-43). Moss discloses that the portions of the device are “the external end portion 28 which is outside of the body; the midportion 30…; and the internal end portion 36 which extends from the pyloric sphincter to the internal end 35 of the device in the proximal segment of the small bowel” (id. at col. 4, ll. 10-16). Moss discloses that a balloon 14 is attached around the main elongated tube 12 (id. at col. 3, 50-58). As can be seen from Moss’s Figures 1 and 2 and the accompanying description, Moss’s balloon is not located proximate the distal end of the gastric tube. The Examiner’s reasoning that extending the proximal portion of the device would result in the balloon being proximate the distal end of the gastric tube is not persuasive since such a modification would not change the relative positions of the balloon and the distal end. Thus, we reverse the rejection of independent claim 1 and dependent claims 2, 3 and 5, as being obvious in view of Moss and Stark. III. The Examiner has rejected claims 15-18, 23 and 24 under 35 U.S.C. § 103(a) as being obvious in view of Freeman, Kraemer and Black. The Examiner has also rejected, under 35 U.S.C. § 103(a), claims 19 and 21 in view of Freeman, Kraemer, Black and Siegmund and claims 20 and 22 in view of Freeman, Kraemer, Black, Siegmund and Greelis. Since the same issue is dispositive for all three rejections, we will consider them together. Appeal 2010-011217 Application 10/966,903 10 Claim 159 is directed to a method for performing gastric reduction surgery that comprises, among other things, using the apparatus of claim 1 to form a gastric pouch smaller than a stomach, connecting the newly-formed gastric pouch to the small bowel of a patient, and leak testing a newly formed gastric pouch by using the apparatus of claim 1 to pressurize the newly-formed gastric pouch to a selected pressure. The Examiner finds that Freeman discloses a gastric reduction surgery method that comprises “forming a gastric pouch smaller than the patient's stomach and connecting the… gastric pouch” to the small bowel (Answer 7- 8). The Examiner finds that Kraemer discloses “an apparatus for evacuating and sizing a stomach comprising a gastric tube,” with an attached balloon (id. at 8). The Examiner finds that Kraemer discloses evacuating stomach contents “through the working channel of tube portion (82)… and discloses collapsing the stomach around the balloon (72) to size the gastric pouch” 9 Claim 15 is as follows: A method for performing gastric reduction surgery comprising: withdrawing stomach contents of a patient by using the combined template, leak and integrity testing apparatus of claim 1, collapsing a stomach of a patient around the combined template, leak and integrity testing apparatus of claim 1, using an inflated said balloon of claim 1 to ascertain size of a gastric pouch, forming a gastric pouch smaller than a stomach, connecting a newly-formed gastric pouch to a small bowel of a patient, leak testing a newly formed gastric pouch by using the combined template, leak and integrity testing apparatus of claim 1 to pressurize the newly-formed gastric pouch to a selected pressure. Appeal 2010-011217 Application 10/966,903 11 (id.). The Examiner concludes that it would have been obvious to one skilled in the art to have modified Freeman’s method to include Kraemer’s device “in order to be able to evacuate the stomach and size the gastric pouch” (id.). The Examiner finds that “anastomotic leak after gastric bypass surgery is a well known complication” (id.). The Examiner finds that Black discloses a device for “testing the integrity of an anastomosis by applying fluid to a vessel and monitoring the pressure” (id.). The Examiner concludes that it would have been obvious to include a pressure-developing and monitoring device as taught by Black… on the [Kraemer] device… so that the integrity of the pouch can be checked without having to remove the sizing device and insert a separate ” device (id.). Appellants argue that the cited references would not have made obvious the combination of Black’s integrity testing device with Kraemer’s pouch sizing and formation device into a single apparatus for use in Freeman’s gastric reduction surgery method (Appeal Br. 37-38). We agree with Appellants that the Examiner has not adequately explained how the cited references would have made obvious the claim 15 method for performing gastric reduction surgery. In particular, we agree with Appellants that the Examiner has not adequately explained why one of skill in the art would have modified the Kraemer’s pouch sizing apparatus to contain an integrity testing component for use in Freeman’s method because Freeman discloses that gastric pouch formation is followed by an anastomosis step that is performed with a transorally inserted anastomosis instrument. Thus, a different instrument is required between the pouch Appeal 2010-011217 Application 10/966,903 12 sizing and formation step and the step where integrity testing would be performed. Freeman discloses a “method to perform a gastric bypass procedure… using surgical tools and anastomosis members inserted transorally” (Freeman, col. 2, ll. 22-24). Figure 4 of Freeman is shown below: Figure 4 is said to show “anastomosis of the drainage loop to the jejunum of a patient” (id. at col. 2, ll. 56-57). Freeman discloses that “[t]wo anastomosis members [anvils 14 and 18] are placed transorally and passed into the distal small intestine” (id. at col. 2, ll. 24-26). Freeman discloses that the “small intestine is transected… to create a drainage loop [44]” (id. at col. 2, ll. 26-28). Freeman discloses that an “anastomosis instrument is inserted transorally to join the most distal anastomosis member [anvil 14] to the drainage loop [44]” (id. at col. 2, ll. 28-30). Freeman discloses that the “stomach is then transected to form a small gastric pouch. An anastomosis Appeal 2010-011217 Application 10/966,903 13 instrument… is inserted transorally to join the more proximal anastomosis member [anvil 18] to the gastric pouch” (id. at col. 2, ll. 31-33). The Examiner’s reasoning is that Kraemer’s apparatus would be used to size and form the gastric pouch in Freeman’s method. However, an anastomosis instrument would be required to be inserted transorally after pouch formation, and any integrity testing would be conducted after anastomosis. Thus, the Examiner has not explained why it would have been obvious to add Black’s integrity testing components to Kraemer’s pouch sizing and formation components since the two sets of components would be required at different points in the procedure, i.e. before and after the use of a different anastomosis device. Thus, we reverse the rejection of claim 15 and the rejection of claims 16-18, 23 and 24, which depend from claim 15 directly or indirectly, as being obvious in view of Freeman, Kraemer and Black. The Examiner has also rejected, under 35 U.S.C. § 103(a), claims 19 and 21 in view of Freeman, Kraemer, Black and Siegmund and claims 20 and 22 in view of Freeman, Kraemer, Black, Siegmund and Greelis. For these rejections, the Examiner relies on Freeman, Kraemer, and Black, as discussed above, and the Examiner relies on Siegmund and Greelis to supply dependent claim limitations. Thus, we also reverse these rejections. SUMMARY We reverse the rejections of claims 1-24 under 35 U.S.C. § 103(a).
