US Patent:

8512400, Aug 20, 2013

Filed:

Apr 9, 2010

Appl. No.:

12/757111

Inventors:

Don Tran - Novato CA, US
Nathan Wiemeyer - Healdsburg CA, US
Susheel Deshmukh - Santa Rosa CA, US
Leonal Mendoza - Rohnert Park CA, US
Matthew Rust - Santa Rosa CA, US

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61F 2/24

US Classification:

623 211, 623 111

Abstract:

A device for percutaneously repairing a heart valve of a patient including a self-expanding, stented prosthetic heart valve and a delivery system. The delivery system includes delivery sheath slidably receiving an inner shaft forming a coupling structure. A capsule of the delivery sheath includes a distal segment and a proximal segment. An outer diameter of the distal segment is greater than that of the proximal segment. An area moment of inertia of the distal segment can be greater than an area moment of inertia of the proximal segment. Regardless, an axial length of the distal segment is less than the axial length of the prosthesis. In a loaded state, the prosthesis engages the coupling structure and is compressively retained within the capsule. The capsule is unlikely to kink when traversing the patient's vasculature, such as when tracking around the aortic arch, promoting recapturing of the prosthesis.

International Classification:

A61F 2/06

US Classification:

623001160

Abstract:

A polymer coating/ring is employed to aid in the sealing and connection of modular elements used in body flow lumens for the exclusion and bypass of diseased regions of the flow lumen, such as where aneurysm occurs adjacent to branching blood vessels.
