Gastric bypass devices and procedures

摘要

Methods and devices for treating obesity are provided, and more particularly, methods and devices for performing gastric bypasses are disclosed. In one exemplary embodiment a gastric bypass procedure is provided that includes forming a gastro-entero anastomosis between a stomach and an intestine and forming an entero-entero anastomosis between a portion of the intestine distal to the gastro-entero anastomosis and a portion of the intestine proximal to the gastro-entero anastomosis. A surrogate path is formed between the esophagus and the gastro-entero anastomosis to at least partially direct fluid from the esophagus to the intestine by way of the gastro-entero anastomosis, thereby bypassing the stomach. A variety of devices that are particularly useful in gastric bypass procedures are also disclosed. The devices include anastomotic devices that can be coupled to or integrally formed with a shunt. The devices can include a plurality of tubular bodies that are configured to have an adjustable length. Still further, methods for repairing an abdominal aortic aneurysm and leaking heart valve are also disclosed.

主权项

1. A method for repairing a heart valve, comprising:
positioning an anastomotic device having proximal and distal portions within a tissue tract that includes a mitral valve having an anterior leaflet and a posterior leaflet, each of which is coupled to an annulus; deploying the anastomotic device by rotation in a first direction to cause one of the proximal and distal portions to radially expand and then by rotation in a second, opposite direction to cause another one of the proximal and distal portions to radially expand to thereby cause a diameter of the annulus to decrease and to enhance coaptation of the anterior and posterior leaflets wherein the anastomotic device is deployed by applying mechanical rotation to the anastomotic device about a longitudinal axis of the anastomotic device.
