摘要:
A method for approximating tissue within a body including the step of providing a device having a handle, at least one actuator, an elongated hollow housing having a proximal end attached to the handle and a distal end extending therefrom, a first and second cartridge. Each the cartridge contains at least one fastener having at least two anchors connected together by a non-resilient flexible suture which does not resist deformation under compressible loads. The first cartridge being releasably connected to the distal end of hollow housing. The method also includes the step of inserting the first cartridge into a body and deploying each anchor into tissue in a spaced apart position. The method also involves moving the anchors adjacent one another by moving the suture in a proximal direction, and removing the first cartridge from the body and from the housing. The method then involves placing the second cartridge onto the housing thereby replacing the first cartridge with the second cartridge.
摘要:
A method and device for manipulating gastric tissue about a greater curvature of a stomach. The method includes the steps of creating at least one incision to gain access to the peritoneal cavity, and dissecting at least a portion of the greater omentum. Then the method includes accessing the exterior of the gastric tissue through the incision and folding at least a portion of the greater curvature of the stomach. The fold is constructed having serosa to serosa contact substantially along its entire length. The method further involves securing the fold with a flexible member wherein the flexible member comprises at least one tissue securing feature.

A device for inducing satiety including an elongated device for insertion through a natural orifice and into a stomach of the patient. The distal end of the device includes a means for occupying space between the submucosal and muscularis layers adjacent a pyloric sphincter. The means has a collapsed state for delivery to a target site and an expanded state for implantation thereof.
摘要:
A method of deploying a surgical fastener including the step of introducing the fastener into a body of a patient while the fastener is in a first shape having a first loop with a back span and an original size and shape. The method involves moving the end segments of the fastener in a first manner away from each other while maintaining the fastener in a closed loop. The method also involves moving the end segments of the fastener in a second manner away from each other to open the loop. The method further involves forming the fastener into a second loop having a width greater than the width of the first loop.

A suture anchoring device includes a fastener body composed of a tube and a spool is mounted within the tube for rotation relative to the tube. Suture material is wrapped about the spool such that pulling of the suture material causes rotation of the spool within the tube. A one-way locking mechanism allows the spool to rotate freely in a first direction and prevents rotation in an opposite direction. A method for creating a tissue fold includes deploying a first suture anchoring device within the tissue with suture material extending proximally from the first suture anchoring device, deploying a second suture anchoring device within the tissue with a distal portion of the suture material extending between the first suture anchoring device and a proximal portion of the suture material extending proximally from the second suture anchoring device, and applying tension to the suture material to draw portions of the tissue together to form a tissue fold.
摘要:
A low-profile surgical stapler enables a large-sized staple to be delivered into a body cavity through a small opening or port. The surgical stapler includes a handle having a trigger movably coupled to the handle. The surgical stapler also includes an elongated, tubular shaft extends distally from the handle. The tubular shaft includes a proximal end secured to the handle and a distal end in which a deployment opening is formed. A staple deploying assembly is disposed within an interior of the shaft for discharging staples 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.

A reloadable device for deploying fasteners including a handle and at least one actuator. The handle is connected to an elongated hollow housing having distal and proximal ends. The device also includes a first cartridge containing at least one fastener releasably connectable to the distal end of hollow housing. 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 for facilitating removal the first cartridge and replacing it with a second cartridge.

摘要:
Devices and methods are provided for forming and securing a tissue plication. More particularly, the devices and methods of the present invention can be used to create multiple tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a method of gastric volume reduction is disclosed that includes advancing a tissue acquisition and fixation device endoscopically into a stomach, manipulating the device to form a first fold of tissue on an interior surface of an anterior wall of the stomach, and manipulating the device to form a second fold of tissue on an interior surface of a posterior wall of the stomach, where the second fold is not attached to the first fold.

More particularly, the devices and methods of the present invention can be used to create multiple tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a tissue acquisition and fixation system is disclosed including a stapling member having first and second jaws that are effective to apply at least one staple to tissue engaged between the jaws, a tissue acquisition member coupled to at least one of the first and second jaws, and a secondary tissue acquirer coupled to the tissue acquisition member. The secondary tissue acquirer is configured to engage tissue and maintain the tissue in position relative to the tissue acquisition member.
