Transcatheter prosthesis with sealing component, and systems and methods for delivering and deployment thereof
First Claim
1. A transcatheter prosthesis having a radially compressed configuration for delivery within a vasculature and a radially expanded configuration for deployment within a native anatomy comprising:
- a frame;
a fixation member extending outwardly from an outer surface of the frame; and
a resilient elongate member slidably disposed within the fixation member, the resilient elongate member having a cross-section with a contracted outer diameter in a radially contracted state when in tension and an expanded outer diameter in a radially expanded state when relaxed, the contracted outer diameter of the cross-section of the elongate member being less than the expanded outer diameter of the cross-section of the elongate member,wherein the resilient elongate member in the radially contracted state is configured to hold the prosthesis in the radially compressed configuration, andwherein at least the resilient elongate member in the radially expanded state provides a seal between the prosthesis and the native anatomy when the prosthesis is in the radially expanded configuration.

Abstract
A transcatheter prosthesis with radially compressed and expanded configurations. An elongate member encircling at least a portion of the prosthesis, and configured to provide a seal between the prosthesis and a native anatomy when the prosthesis is deployed in the radially expanded configuration. The elongate member may be a resilient elongate member having a radially contracted state, when in tension, to hold at least the portion of the prosthesis in the radially compressed configuration, and having a radially expanded state, when relaxed, to provide the seal between at least the portion of the prosthesis and a native anatomy when the prosthesis is deployed. A system for delivering the transcatheter prosthesis may include a delivery catheter having an elongate cinching member encircling at least a second portion of the prosthesis, wherein the elongate cinching member is configured to hold the second portion of the prosthesis in the radially compressed configuration.

13. A method of deploying and sealing a prosthesis within a native anatomy comprising:
-
loading a prosthesis with a fixation member and a resilient elongate member onto a delivery catheter, wherein the resilient elongate member is slidably disposed within the fixation member, has a cross-section with a contracted outer diameter in a radially contracted state when in tension and the cross-section has an expanded outer diameter in a radially expanded state when relaxed, the contracted outer diameter of the cross-section of the elongate member being less than the expanded outer diameter of the cross-section of the elongate member, and the resilient elongate member is configured to hold the prosthesis in a radially compressed configuration when in the radially contracted state; positioning the prosthesis in the radially compressed configuration at the native anatomy; and releasing the resilient elongate member to permit the prosthesis to return to a radially expanded configuration and to permit the resilient elongate member to return to the radially expanded state such that at least the resilient elongate member seals between the prosthesis and the native anatomy to prevent blood flow therebetween. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
