Appl. No.:

10/096263

Inventors:

Sidney Fleischman - Menlo Park CA, US
Thomas Campbell - Brentwood CA, US
Patrick Owens - Half Moon Bay CA, US
Deborah Tolomeo - San Jose CA, US
Rose Leo - Hayward CA, US

International Classification:

A61B017/08

US Classification:

606/153000

Abstract:

Sutureless anastomosis system deployment concepts are disclosed herein. Specifically, anastomosis strain relief devices are disclosed which are disposed, at least partially, over an anastomosis bypass graft just proximal to an attachment site between a host vessel wall and the fitting. The strain relief devices provide additional support to the graft while preventing kinking of the graft, especially when it emanates at acute angles from the anastomosis site. Furthermore, the strain relief provides additional support to the graft during manipulations involved in inserting and attaching ends of the graft. The devices can have a variety of configurations, e.g., helical, zig-zag, etc., depending upon the desired functionality. The strain relief may also be either incorporated into the graft or placed exterior to the graft and bonded. Moreover, integrated fittings or collars may be incorporated into the strain relief to expand its functions.

International Classification:

A61B 1739
A61N 105

US Classification:

606 41

Abstract:

A porous electrode assembly for tissue heating and ablation systems and methods includes a wall having an exterior peripherally surrounding an interior area. The assembly includes a lumen to convey a medium containing ions into the interior area. An element couples the medium within the interior area to a source of electrical energy. According to the invention, the wall includes at least two spaced apart zones. Each zone comprises a porous material sized to pass ions contained in the medium, to thereby enable ionic transport of electrical energy from the source through the medium and porous material to the exterior of the wall. In a preferred embodiment, the at least two zones are spaced apart by a third zone comprising a material that blocks passage of ions contained in the medium.
