Transcatheter valve prosthesis and a concurrently delivered sealing component
First Claim
1. A transcatheter valve prosthesis comprising:
- a tubular stent having a compressed configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve;
a prosthetic valve component disposed within and secured to the tubular stent; and
an annular sealing component coupled to and encircling an outer surface of the tubular stent, the sealing component including a cylindrical sleeve formed of a flexible material and a plurality of ribs longitudinally extending over the cylindrical sleeve, each rib of the plurality of ribs longitudinally extending at least from a first end of the cylindrical sleeve to a second opposing end of the cylindrical sleeve, wherein the sealing component has a delivery configuration in which the cylindrical sleeve lays flat against the outer surface of the tubular stent and a deployed configuration in which at least a portion of each rib of the plurality of ribs is sinusoidal and cause at least a portion of cylindrical sleeve to buckle outwardly away from the outer surface of the tubular stent.

Abstract
A method of preventing paravalvular leakage includes concurrent delivery of a heart valve prosthesis and an annular sealing component. During delivery, the sealing component is moved from a first position to a second position of the heart valve prosthesis which is longitudinally spaced apart from the first position of the heart valve prosthesis. The sealing component is secured around the heart valve prosthesis at the second position by a contoured outer surface of the heart valve prosthesis. The sealing component may be a flexible ring or may be a cylindrical flexible sleeve having a plurality of ribs longitudinally extending over the cylindrical sleeve. The ribs operate to deploy the sealing component such that at least a portion of the cylindrical sleeve buckles outwardly away from the outer surface of the heart valve prosthesis.
