A compression clip system where compression is used to close a tissue opening, reduce the volume of an organ, ligate dilated blood vessels or compress tissue adjacent to various other types of lesions to induce healing. Compression prevents bleeding and the leakage of body fluids into a body cavity. The opening may be surgery induced as in gastrectomies or formed naturally such as peptic ulcers and hemorrhoids. The system may include a compression clip, a suitable clip applier, a grasper assembly and an endoscope all brought to the compression site via a multi-lumen sleeve.

Devices and methods are provided for ablational treatment of regions of the digestive tract in post-bariatric surgery patients who fail to achieve or maintain the desired weight loss. Bariatric procedures include Roux-en-Y gastric bypass, biliopancreatic diversion, and sleeve gastrectomy. These procedures reconstruct gastrointestinal tract features, creating pouches, stoma, and tubes that restrict and / or divert the digestive flow. Post-surgical dilation of altered structures is common and diminishes their bariatric effectiveness. Ablation of compromised structures can reduce their size and compliance, restoring bariatric effectiveness. Ablation, as provided the invention, starts at the mucosa and penetrates deeper into the gastrointestinal wall in a controlled manner. Control may also be provided by a fractional ablation that ablates some tissue within a target region and leaves a portion substantially unaffected. Embodiments of the device include an ablational electrode array that spans 360 degrees and an array that spans an arc of less than 360 degrees.

Methods and devices are provided for performing gastrectomies and gastroplasties. In one embodiment, a method includes gaining access to a stomach of a patient through an opening formed in the patient's abdominal wall and an opening formed in the patient's vaginal wall. Tissue attached to the stomach can be tensioned using a surgical instrument inserted through one of the abdominal and vaginal openings and can be separated from the stomach to free the stomach fundus using a dissecting surgical instrument inserted through another opening, e.g., through one of the abdominal and vaginal openings. The fundus can be at least partially transected using a surgical stapler inserted through one of the abdominal and vaginal openings, thereby forming a stomach ''sleeve.'' In another embodiment, the method is modified to form another opening in the patient's abdominal wall instead of forming an opening in the vaginal wall.

A safe sleeve gastrectomy reduces gastric volume of a patient's stomach as a weight loss treatment. The safe sleeve gastrectomy utilizes a safety pocket created by a surgeon to increase safety and guide division of the stomach. An instrument tunnel is created to facilitate division of the stomach into a pouch and a sectioned portion. In this manner, over or complete mobilization of the stomach is avoided. The sectioned portion may be lifted for increased visibility to facilitate its mobilization and removal from the patient.

An endoscopic stent for implantation in a patient following sleeve gastrectomy or biliopancreatic diversion with duodenal transposition comprises a stent portion comprising a proximal portion, the proximal portion Defined by a length of about 50 mm to about 200 mm; an enlarged intermediate portion having an enlarged diameter relative to the proximal and distal portions and defined by a length of about 20 mm to about 80 mm; and a distal portion and a polymeric sheath portion joined to and extending distally from said distal end portion of said stent.

The invention discloses a guiding device in gastrectomy, which comprises a flexible traction tube and a flexible curved tube, the curved tube is connected with the traction tube, and a plurality of acoustic holes are arranged on the curved tube along the length direction, and each of the acoustic holes is provided with a plurality of acoustic holes. There are sound-emitting parts, and the connection line between any two sound holes is not parallel to the length direction of the elbow. By pulling the traction tube, the elbow is placed in the stomach, and the stomach is excised according to the shape of the elbow. When the excision position is offset, the elbow is compressed, so that the gas in the elbow flows through the sound hole and triggers the sound-producing part to produce sound. The component emits a sound to alert the operator; in addition, the arrangement of the sound holes can avoid the situation where the stomach wall covers all the sound holes and cannot produce sound. The invention can accurately locate the excision position of the stomach, so that the shape of the remaining gastric bag is more regular and controllable, and the structure is simple and easy to operate.
