Devices and methods for placement of partitions within a hollow body organ

Abstract

Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body to create one or more plications within the hollow body organ. A tissue treatment device attached to a distal end of a flexible elongated member and has a cartridge member opposite an anvil member. The cartridge member and the anvil member are movable between a closed position and an open position relative to one another, and the cartridge member is re-loadable with a removable staple cartridge to form multiple plications within the organ with the same tissue treatment device.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation-in-part of co-pending application Ser. No. 10 / 797,303 filed on Mar. 9, 2004, which is herein incorporated by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to medical devices and methods. More particularly, it relates to devices and methods for creating a partition within a hollow body organ, particularly a stomach, intestinal tract, or other region of the gastrointestinal tract, and affixing the tissue. [0004] 2. General Background and State of the Art [0005] In cases of severe obesity, patients may currently undergo several types of surgery either to tie off or staple portions of the large or small intestine or stomach, and / or to bypass portions of the same to reduce the amount of food desired by the patient, and the amount absorbed by the gastrointestinal tract. The procedures currently available include laparoscopic banding, wher...

AI Technical Summary

Benefits of technology

The patent describes devices that can be used to create a partition within a hollow body organ, such as a stomach, to reduce the size of the stomach or create a smaller pouch. The devices can be placed within the organ using minimally invasive methods, such as endoscopy or percutaneously. They can be designed to automatically adjust to the tissue they acquire and can be used to create a small gastric pouch or restrictive partition. The devices can be used to treat obesity or gastrointestinal disorders.

Problems solved by technology

Moreover, the devices are configured such that once acquisition of the tissue is accomplished, manipulation of the acquired tissue is unnecessary as the devices are able to automatically configure the acquired tissue into a desired configuration.
