System and method for anchoring stomach implant

摘要

A gastric implant system includes a gastric implant such as a restrictive pouch or a gastric balloon, an anchor passable through the mouth and stomach and further through the stomach wall into engagement with abdominal wall tissue. When the anchor is engaged to abdominal wall tissue, the stomach wall and abdominal wall are brought into contact with one another such that a proximal portion of the anchor extends into the stomach interior while a distal portion of the anchor remains engaged to the abdominal wall. A locking element coupled to the proximal section of the anchor is sued to maintain contact between the stomach wall and abdominal wall. The gastric implant is advanced through the oral cavity into the stomach and is coupled to the anchor.

1. A method of anchoring an implant in a patient's stomach, comprising:
introducing transorally into the stomach an anchor, wherein the anchor includes an expandable head at a distal end; passing the head of the anchor into a wall of the stomach in a contracted condition within a medical device, wherein the passing step includes placing the medical device within the stomach and piercing the wall of the stomach with the medical device; positioning the medical device within an abdominal fascia; after the positioning step, releasing the anchor from the medical device; expanding the head to an expanded condition to attach the anchor relative to the stomach wall; advancing a spacer towards the anchor and into contact with the stomach wall; positioning the implant within the stomach such that the spacer is positioned between the implant and the stomach wall; and removing the spacer from the patient.
