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.
