Abstract

A stapling device for a surgical endoscopic device provided with at least one flexible portion, comprising a staple-firing portion and an anvil portion, wherein one of the staple firing portions and one of the anvil portions are located longitudinally displaced from one another along the longitudinal axis of the endoscopic device, with at least a part of said flexible portion between them. The parts of the stapling device are in correct working relationship when one or more alignment and/or locking pins or screws that are stored in one of the staple firing portions or one of the anvil portions are extended and engage and lock or screw into receptacles that have been provided on the other of the staple firing portion or of the anvil portion.

Claims

1-41. -41. (canceled)

42. A device for performing a fundoplication surgical procedure, comprising an articulation system and means for rotating said articulation system within the stomach.

43. A device according to claim 42, wherein the articulation system is configured to bend by up to 270°

.

44. A device according to claim 42, wherein the articulation system is configured to bend in one direction only.

45. A device according to claim 42 further provided with clamping means actuatably coupled to the articulation system.

46. A device according to claim 42, further comprising an endoscopic optical system.

47. A device according to claim 42, wherein the system is configured to bend by no more than about 270°

.

48. A method for treating GERD comprising performing a fundoplication surgical procedure using an endoscopic device provided with an articulation system, said method comprising the steps of engaging the fundus and the esophagus at one location by articulating the articulation system and then rotating the articulated section of the endoscopic device to a second location.

49. A method according to claim 48, further comprising the step of engaging the fundus and the esophagus at the second location.

50. A method according to claim 48, further comprising the step of repeating at least once the engaging and rotating steps for additional locations for a number of times necessary to complete the fundoplication procedure.

51. A method according to claim 48, wherein prior to performing the step of rotating the articulated section to the second location, at least partially reversing the articulating procedure, rotating the articulated section of the endoscopic device to the second location and rearticulating the articulation system.

52. A method according to claim 48, wherein articulating the articulation system clamps the engaged fundus and esophagus, the method further comprising the steps of fixedly plicating the fundus to the esophagus by fastening the fundus to the esophagus using at least one surgical fastener and, after the fastener(s) have been used, releasing said clamping prior to rotating the articulated section of the endoscopic device to the second location.

53. A method according to claim 52, wherein the articulation system clamps said fundus to said esophagus after placation so as to maintain the fundus and esophagus in a close, fixed positioned relationship during fastening.
