US Patent:

20070156229, Jul 5, 2007

Filed:

Dec 30, 2005

Appl. No.:

11/323013

Inventors:

Jin Park - Parsippany NJ, US

International Classification:

A61F 2/06

US Classification:

623001150

Abstract:

A bifurcated prosthetic stent graft has two stent grafts with co-located respective first ends, and disparately located respective second ends. Each stent grafts includes a first stent segment at the first end of the stent graft having a semicircular portion and a diameter portion connecting the ends of the semicircular portion and held in tension by the ends of the semicircular portion, defining a substantially D-shape. Compression and heat applied to the diameter portion during manufacture of the stent results in the diameter portion being in tension when the stent is deployed. One or more transition segments transitions the stent graft between a substantially D-shape and a substantially circular shape. A vascular graft encloses the first stent segment and one or more transition stent segments, the vascular graft providing a fluid flow lumen from the first end of the stent graft to the second end.

International Classification:

A61F 2/01

US Classification:

606200000, 14007100R, 083013000

Abstract:

In accordance with the present invention, a distal protection and embolic material retrieval device with improved apposition to both large and small vessel walls of varying geometries for enhancing the filtering of embolic material during intravascular procedures while allowing for the passage of blood is provided. The device includes a filter basket designed to maximize apposition of the filtering portion to that of the vessel wall and may include struts which provide circumferential support to the filtering membrane and thereby minimizing or eliminating in-folding of the filter basket. Thin film materials may also be utilized for the filtering membrane of the filter basket. In addition one can incorporate biological and/or pharmaceutical agents in combination with the present invention.

- Beijing, CN
Jin PARK - Morris Plains NJ, US

Assignee:

ACCUMEDICAL BEIJING LTD. - beijing

International Classification:

A61B 17/221
A61F 2/01

Abstract:

The present invention pertains to a thrombectomy device comprising a cylindrical proximal portion and one or more radiopaque segments. The cylindrical proximal portion forms a stent frame having an outer lattice network of an outer plurality of interconnecting segments. The outer plurality of interconnecting segments are configured to exert a radial force against an inner wall of a blood vessel. The radiopaque segment is formed from a plurality of radiopaque wires extending from the outer stent frame to a central axis of the thrombectomy device along a length of the stent frame. The radiopaque segment converges to a tip along with the central axis.
