First Claim
Patent Images
1. A replacement valve for use within a human body comprising:
- a valve component comprising an outer surface covered at least partially with a fabric skirt configured to extend below the valve component; and
a stent component for housing the valve component,wherein the stent component and valve components are configurable into at least a collapsed configuration for percutaneous delivery and an expanded configuration after implantation, a free edge of the fabric skirt wraps a bottom portion of the stent component and is affixed to the stent component via a plurality of sutures; and
at least a portion of the fibers of the fabric skirt are oriented at substantially 45 degrees with respect to a longitudinal axis of the valve component in the expanded configuration.

Abstract
A stent-valve having a valve component and a stent component for housing the valve component, as well as associated methods and systems for delivery of the stent-valve via minimally-invasive surgery. The stent-valve can be configurable between two or more configurations to assist in delivery of the stent-valve to an implantation site of a patient.

18. A replacement valve for use within a human body comprising:
-
a valve component comprising an outer surface covered at least partially with a fabric reinforcement; a stent component housing the valve component therein; and a fabric skirt; wherein the stent component and valve components are configurable into at least a collapsed configuration for percutaneous delivery and an expanded configuration after implantation; wherein at least a portion of the fabric skirt is disposed on an outer surface of the stent component and affixed to the stent component via at least one suture; and wherein at least a portion of the fibers of the fabric reinforcement are oriented at substantially 45 degrees with respect to a longitudinal axis of the valve component in the expanded configuration. - View Dependent Claims (19, 20)
