US Patent:

20040019375, Jan 29, 2004

Filed:

Jul 26, 2002

Appl. No.:

10/206620

Inventors:

Thomas Casey - Grafton MA, US
Kristoff Nelson - Boston MA, US
Fergus Quigley - Watertown MA, US

Assignee:

SCIMED Life Systems, Inc.

International Classification:

A61F002/06

US Classification:

623/001280, 264/299000, 623/903000

Abstract:

The present invention provides a sectional crimped graft that allows graft flexibility where required and limits the overall longitudinal extension. The present invention overcomes the disadvantage of fully crimped grafts by controlling the number of crimps per unit length, crimp height, crimp geometry and their location along the graft wall, dependent on the particular end-use application. In so doing, flexibility and elongation can be controllably tailored only in areas where significant anatomical angulation is present. It may also be useful in applications other than stent grafts such as surgical grafts for aortic and peripheral areas. Limiting the overall graft longitudinal extension also facilitates the deployment of the stent-graft into the blood vessel.

Inventors:

Thomas V. Casey - Grafton MA, US

International Classification:

A61M 25/18

US Classification:

604247

Abstract:

A valve may include (a) a housing defining a valve lumen adapted for fluid connection with a lumen of a catheter; (b) a substantially conical valve member coupled to the housing and extending across the valve lumen to control flow therethrough; (c) a plurality of slits extending through the valve member and separated from one another circumferentially around the valve member; and (d) a ramp formed within a distal end of the valve lumen extending proximally from a distal tip of the valve member toward a ramp vertex separated from the distal tip by a predetermined distance.
