Abstract:
Systems and methods are disclosed for the inversion of gastro intestinal diverticula and repair of associated intestinal wall tissue by means of endoscopy through a natural orifice such as the mouth or anus without making incisions in the abdominal wall or opening the peritoneal cavity.
Abstract:
To close a translumenal hole made in the stomach (or colon, etc.) pursuant to natural orifice surgical treatment of tissue in the peritoneal cavity, one or more guides (24) are engagd with the hole, and the guides (24) can be pulled to purse together tissue on opposite side of the hole. A closure device (12) is then advanced along the guides (24) over the pursed tissue to adhere the tissue together using heat, staples, sutures, etc.
Abstract:
A mesh to repair a hole in a muscle wall includes a resilient mesh body (20) and fortifying structure (22) such as mesh portions of thicker weave than other portions, or strengthening members that can be engaged with the mesh and then removed from the mesh once the mesh is place over the hole. The same principles can be applied to a plug (204) that is engaged with the mesh for filling the hole.
Abstract:
A space in a muscle wall such as the inguinal canal is dilated to break up fibrotic bands by divulsion. While the space is dilated a dynamic plug (100A-100G) is advanced into it, with the plug expanding and contracting with the space. Shields (28, 66) may be placed against opposite sides of the wall surrounding the space.
