Transcatheter heart valve replacement systems, heart valve prostheses, and methods for percutaneous heart valve replacement
First Claim
1. A heart valve prosthesis for implantation at a native valve region of a heart, the prosthesis comprising:
- an expandable frame defining a lumen through which blood may flow, the lumen extending from a first end to a second end thereof, wherein the frame includes a plurality of commissure posts extending from the first end;
a tubular component attached to the plurality of commissure posts, the tubular component having a first portion and a second portion and a channel formed in a wall thereof, wherein an interior of the tubular component is configured to support a prosthetic valve;
a locking mechanism secured within the lumen of the expandable frame; and
a wire operably coupled to the locking mechanism, the wire being at least partially slideably disposed within the channel of the tubular component, wherein the locking mechanism is configured to permit the wire to be advanced within the channel of the tubular component to thereby transition the tubular component into a deployed configuration.

Abstract
A transcatheter heart valve prosthesis configured in accordance herewith includes an expandable frame having a plurality of commissure posts extending therefrom, a radially expandable tubular component attached to the plurality of commissure posts, and a locking mechanism operably coupled to a wire. The wire is at least partially slideably disposed within a channel formed in a wall of the tubular component and the locking mechanism is configured to permit the wire to be advanced within the channel to thereby transition the tubular component into a deployed configuration that at least partially engages tissue at the native heart valve.

12. A system for repair or replacement of a heart valve, the system comprising:
-
a prosthetic heart valve comprising, an anchoring structure, a tubular component coupled to and extending from the anchoring structure, the tubular component defining a lumen and having a channel within a wall thereof, a prosthetic valve component disposed within the lumen of the tubular component, the prosthetic valve component configured to inhibit retrograde blood flow through the lumen, an elongated stiffening element at least partially disposed within the channel of the tubular component to thereby transition the tubular component and the prosthetic valve component into a deployed configuration, and a locking mechanism secured to the anchoring structure and coupled to the stiffening element; and a catheter assembly configured to deliver and deploy the prosthetic heart valve, the catheter assembly comprising, a handle assembly having a first actuator for operating the locking mechanism to advance the stiffening element within the channel of the tubular component, and an engagement tube extending from the handle assembly, the engagement tube configured to operatively engage the locking mechanism at a proximal end thereof upon actuation of the first actuator. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
