Multiple-Sided Intraluminal Medical Device
US Patent:
6508833, Jan 21, 2003
Filed:
Mar 12, 2001
Appl. No.:
09/804128
Inventors:
Dusan Pavcnik - Portland OR
Frederick S. Keller - Portland OR
Josef Rosch - Portland OR
Thomas A. Osborne - Bloomington IN

Assignee:
Cook Incorporated - Bloomington IN
International Classification:
A61F 206
US Classification:
623 115, 623 121, 623 124, 623 213, 623 214, 623 217, 623 218
Abstract:
A multiple-sided medical device comprises a closed frame of a single piece of wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration that comprises a self-expanding stent. The stent is pushed from a delivery catheter into the lumen of a duct or vessel. One or more barbs are attached to the frame of the device for anchoring or to connect additional frames. A covering of fabric or other flexible material such as DACRON, PTFE, or collagen, is sutured or attached to the frame to form an occlusion device, a stent graft, or an artificial valve such as for correcting incompetent veins in the lower legs and feet. A partial, triangular-shaped covering over the lumen of the device allows the valve to open with normal blood flow and close to retrograde flow.

International Classification:
A61B 17/12
US Classification:
606191
Abstract:
An occlusion device has a covering attached to a support frame that includes a disc-shaped member and a crossbar that extends across a central opening defined by the disc-shaped member. The occlusion device has a first, or deployed, configuration in which the crossbar defines a curve that extends from the disc-shaped member, and a second, or resting, configuration in which the disc-shaped member and the crossbar lie substantially in a single plane. Each of the disc-shaped member and the crossbar include a core wire that extends through a lumen of a coil multiple times.

International Classification:
A61F002/06
US Classification:
623001240, 623002180
Abstract:
A multiple-sided valve for implantation within a body vessel comprising a frame comprising a bioabsorbable material is provided. The devices can be pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs for anchoring purposes. A full or partial covering of fabric or other flexible material, or a bioabsorbable material, including a collagen-based material such as small intestinal submucosa (SIS), may be attached to the frame to form an occlusion device, a graft, or an implantable, intraluminal valve such as for correcting incompetent veins in the lower legs and feet.
