US Patent:

7163556, Jan 16, 2007

Filed:

Mar 21, 2002

Appl. No.:

10/104499

Inventors:

Hua Xie - Beaverton OR, US
Lisa A. Buckley - New York NY, US

Assignee:

Providence Health System - Oregon - Seattle WA

International Classification:

A61F 2/24
A61F 2/06

US Classification:

623 214, 623 124

Abstract:

A bioprosthetic valve graft comprises a valve frame and valve flaps, the latter acting to open or close a valve aperture to directionally control fluid flow through the bioprosthesis. The bioprosthetic valve graft comprises a biomaterial suturelessly bonded to the valve frame, avoiding sutures and substantially reducing medical complications in implantations.

US Classification:

623 113

Abstract:

A bioprosthetic stent graft is disclosed, having a stent frame and a biomaterial sheath suturelessly bonded to the stent frame. Sutureless bonding avoids sutures and substantially reducing medical complications in implantation of the stent graft. A device and method for manufacturing the stent graft further is disclosed. A mandrel is employed for shaping the stent graft, and means for irradiating the biomaterial effects sutureless bonding.

Abstract:

A bioprosthetic valve graft comprises a valve frame and valve flaps, the latter acting to open or close a valve aperture to directionally control fluid flow through the bioprosthesis. The bioprosthetic valve graft comprises method for suturelessly attaching a biomaterial suturelessly bonded to the A method for securing a biomaterial to a valve frame includes positioning a flexible valve frame defining an open area on a first major surface of a biomaterial sheet having a peripheral edge, wherein positioning serves to approximate the valve frame and the peripheral edge of the biomaterial sheet to form an at least first bonding locus; and suturelessly bonding the biomaterial to the valve frame at the at least first bonding locus. The method avoids the disadvantages associated with conventional sutures and substantially reduces medical complications in implantations.
