摘要:
A tissue conveyor (24) includes a conveyor body (25) having a proximal end (28) and a distal end (30). The proximal end includes a handle (32) allowing for operator control of an end effector (34) located at the distal end. The end effector includes a grasper assembly (38) composed of a first jaw bar (40) and a second jaw bar (42) connected by a support base (44) to define a cavity into which tissue is drawn. A first conveyor member (62) is positioned upon the first jaw bar for movement along an internal surface of the first jaw bar and a second conveyor member (64) is positioned upon the second jaw bar for movement along an internal surface of the second jaw bar. The method for creating a tissue fold includes positioning a tissue conveyor adjacent tissue, pushing the respective first jaw bar and the second jaw bar into the tissue in the area where a fold is desired, and pulling the first conveyor member and the second conveyor member proximally to draw the first and second conveyor members and tissue into a cavity defined by the first jaw bar and the second jaw bar to create a tissue fold.

A method for endoscopically preventing insufflation of the small bowel during gastric procedures includes applying an obstruction member at the pyloric sphincter to block the passage of gas from the gastric cavity into the small bowel and insufflating the gastric cavity.
摘要:
A reloadable device for deploying fasteners. The device has a handle and at least one actuator. The handle is connected to an elongated hollow housing having distal and proximal ends. The device has a first cartridge containing at least one fastener releasably connectable to the handle. The fastener has at least two anchors connected together by a non-resilient flexible suture which does not resist deformation under compressible loads. The device also includes a means, adjacent the handle, for facilitating removal of the first cartridge from the handle and replacing it with a second cartridge.

An inflatable medical instrument (18) for tissue damage in gastric reduction surgery includes a main chamber (20) composed of a biocompatible material capable of being selectively inflated. The medical instrument also includes a longitudinally extending tab member (26) secured to an outer surface of the main chamber, a series of suction holes (30) are formed along the tab member and an electrode (38) is mounted on the tab member. The present invention also provides a method for forming a tissue junction used in defining a gastric pouch including damaging opposed tissue layers, apposing the tissue layers and fastening the tissue layers to allow the tissue layers to heal together.

A system for tissue apposition includes a delivery assembly having a tissue clip selectively secured thereto for the deployment and application of the tissue clip. The tissue clip is shaped and dimensioned for engaging spaced locations along a span of tissue and upon rotation thereof drawing the spaced locations together into apposition to thereby create a fold of tissue.
摘要:
An implant (10) for placement within a hollow body organ. The implant has a member (14) with distal and proximal ends. The member has an undeployed shape for delivery to the hollow body and a deployed shape for implantation therein. The implant has at least one tensioning tether (80) with a first end attached to at least one of the distal and proximal end and a second ends attached to the member between the distal and proximal ends. Wherein applying tension to the tether moves the member towards the deployed shape. The member preferably has a first rate at which it initially resists bending, and a second substantially higher rate at which it resists further bending.
摘要:
A cartridge (24) containing a fastener. The cartridge has an elongated sheath (180) containing at least one tissue penetrating member (90). The penetrating member at least partially houses a fastener. The fastener has at least two anchors (100) connected together by a non-resilient flexible suture (106) which does not resist deformation under compressible loads. The cartridge further includes a means for deploying the anchors, wherein the means is movable within the sheath.
摘要:
A low-profile surgical stapler (10) enables a large-sized staple (12) to be delivered into a body cavity through a small opening or port. The surgical stapler includes a handle (16) having a trigger (20) movably coupled to the handle. The surgical stapler also includes an elongated, tubular shaft (22) extending distally from the handle. The tubular shaft includes a proximal end (24) secured to the handle and a distal end (26) in which a deployment opening (32) is formed. A staple deploying assembly (28) is disposed within an interior of the shaft (22) for discharging staples (12) from the deployment opening at the distal end of the shaft, the staple deploying assembly supporting a staple such that a longitudinal axis of the staple is aligned with a longitudinal axis of the shaft. The deployment opening is shaped and dimensioned to permit the deployment of the staples from within the shaft, out of the deployment opening and into adjacent tissue.
