Transcatheter valve with paravalvular leak sealing ring
First Claim
1. A method of delivering a prosthetic heart valve to a patient comprising:
- loading the prosthetic heart valve into an outer sheath of a delivery device in a collapsed condition, the prosthetic heart valve including a collapsible and expandable stent extending from an inflow end to an outflow end, a plurality of valve leaflets coupled to the stent, and a sealing ring coupled to the stent adjacent the inflow end, the sealing ring including a tube;
advancing the delivery device to a native valve annulus of the patient; and
fully deploying the prosthetic heart valve from the outer sheath and into the native valve annulus so that the prosthetic heart valve transitions from the collapsed condition to an expanded condition;
wherein the tube has a profile that increases from a reduced profile to an enlarged profile as the prosthetic heart valve transitions from the collapsed condition to the expanded condition.

Abstract
A prosthetic heart valve includes a collapsible and expandable stent extending from an inflow end to an outflow end and a plurality of prosthetic valve leaflets coupled to the stent. The prosthetic heart valve may also include a sealing ring coupled to the inflow end of the stent, the sealing ring comprising a tube extending circumferentially around the inflow end of the stent. The tube may be formed from a wire coiled into a repeating shape, such as a rectangle or a diamond, so that the tube is collapsible. A covering may at least partially surround the tube. The sealing ring may include a first filler positioned within the tube and/or a second filler positioned between the tube and the covering.
