SYSTEMS AND METHODS OF SEALING A DEPLOYED VALVE COMPONENT
First Claim
1. A sealing system comprising:
- a valve component including a frame and a prosthetic valve coupled to the frame, the valve component having a radially expanded deployed configuration, an inflow portion and an outflow portion, the frame defining a central passage, the prosthetic valve disposed within the central passage of the frame; and
an expandable sealing component including a sealing frame and a skirt coupled to the frame, the expandable sealing component configured to be inserted in a radially compressed configuration within the central passage with the valve component in the radially expanded deployed configuration, the expandable sealing component further configured to be radially expanded to a radially expanded configuration partially within the valve component such that a first portion of the sealing component is disposed within the valve component and a second portion of the sealing component is disposed longitudinally outside the valve component, the expandable sealing component configured to prevent blood flow radially between the valve component and a wall of the native valve complex.

Abstract
A sealing system for sealing a valve component in a radially expanded deployed configuration includes a valve component and an expandable sealing component. The valve component includes a frame and a prosthetic valve coupled to the frame. The frame defines a central passage with the prosthetic valve disposed therein. The expandable sealing component includes a sealing frame and a skirt coupled to the sealing frame. The expandable sealing component is configured to be inserted in a compressed configuration within the central passage of the valve component with the valve component in the radially expanded deployed configuration. The expandable sealing component is configured to be radially expanded partially within the valve component, with a first portion disposed within the valve component and a second portion disposed longitudinally outside the valve component. The sealing frame may include a first ring and a second ring.

14. A method of correcting paravalvular leakage of an installed valvular prosthesis, the valvular prosthesis including a frame and a prosthetic valve coupled to the frame, the method comprising the steps of:
-
advancing an expandable sealing component in a radially compressed configuration to a location partially within a portion of the frame of the valvular prosthesis with the frame in a radially expanded configuration within a native valve complex, the expandable sealing component including a sealing frame and a skirt coupled to the sealing frame; and expanding the expandable sealing component to a radially expanded configuration such that the expandable sealing component prevents blood flow radially between the valvular prosthesis and a wall of the native valve complex. - View Dependent Claims (15, 16, 17, 18, 19)
