US Patent:

7815656, Oct 19, 2010

Filed:

Aug 11, 2006

Appl. No.:

11/464036

Inventors:

Matthew Rust - Santa Rosa CA, US
Prema Ganesan - San Francisco CA, US
Curtis Hanson - San Diego CA, US
Jack Chu - Santa Rosa CA, US

Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA

International Classification:

A61B 17/08

US Classification:

606153, 623 135

Abstract:

The invention provides a method of providing an endovascular bypass. The method includes the steps of inserting an elastic needle carrying a guidewire adjacent an ostium via a catheter and extending the needle through a branch vessel wall. The method continues by extending the needle through the extravascular space and inserting the needle through a main vessel wall to create an opening. The needle is retracted, leaving the guidewire in place. A bypass stent graft is inserted along the guidewire to provide a pathway between the branch vessel and the main vessel, and the inserted bypass stent graft is expanded. The branch vessel is occluded between the ostium of the bypass stent graft and the main vessel, and a main stent graft is inserted in the main vessel proximate the opening in the main vessel wall.

International Classification:

A61F 2/06

A61F 2/84

US Classification:

623 113, 623 135, 623 136, 623 137

Abstract:

A stent graft includes at least one aperture extending through the main body thereof, into which an extension portion may be deployed for positioning within an adjacent branch flow lumen. The extension portions include self biasing features, wherein the extension is biased into engagement with the main body to seal the interface thereof. Additionally, the extension portion may be configured for tortuous or deviated anatomy, to enable sealing of the extension portion with the body while extending the extension portion in a substantially non-radial direction from the main body.

International Classification:

A61F 2/06

US Classification:

623 113

Abstract:

A method includes deploying a fenestration segment stent-graft into a main vessel such that a fenestration section of the fenestration segment stent-graft covers a first branch vessel emanating from the main vessel. The fenestration segment stent-graft includes a proximal section, a distal section, and the fenestration section attached to and between the proximal section and the distal section. The fenestration section has a greater resistance to tearing than the proximal section and the distal section facilitating formation of a collateral opening aligned with the branch vessel in the fenestration section.
