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:
This invention relates to mutant enzymes with enhanced properties and processes for oxidation of organic compound substrates using such enzymes.
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:
A process for oxidising a substrate which is an acyclic or cyclic terpene, or a cycloalkene; or a substituted derivative thereof, which process comprises oxidising said compound with a mutant haem-containing enzyme, the mutant comprising the substitution of an amino acid in the active site by an amino acid with a less polar side-chain. The enzyme is typically P450cam or P450BM-3. Cells and libraries of cells in which the process can be carried out or which can be used to select advantageous mutant enzymes are also provided.
Abstract:
A transuterine cannula (40, 100, 130, 172, 180, 200, 220, 226) through which an endoscope (46, 106, 132, 150, 252) can be advanced into the peritoneal space to provide visualization of tissue cutting in the peritoneal space pursuant to a vaginal hysterectomy.
Abstract:
An arcuate nitinol splint (10, 40, 50) with a rounded cross-section has two ends facing each other and spaced from each other. The splint is advanced through the mouth into the esophagus by an introducer device. By means of the device the splint is implanted completely into the wall of the esophageal sphincter to strengthen the sphincter. Materials other than Nitinol may be used.
Abstract:
A compression ring (28, 64, 74, 80, 88, 92, 96, 102, 108, 114, 120, 144, 152, 200, 210, 212, 228, 262) to grip and compress body structure such as diverticulum, hemorrhoids, and tissue adjacent a hole. A resilient ring-shaped body defines a compression channel, and one or more axially rigid elongated spikes (70, 78, 86, 94, 98, 104, 106. 112, 326, 206) extend from the body into the channel. The body defines a first axial segment (64a, 82) surrounding the compression channel and a second axiai segment (64b, 84) surrounding the compression channel, with the spike being engaged only with the second axial segment. The first axial segment more tightly compresses the body structure than the second axial segment.
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 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.
