摘要： A loading tool for loading a collapsible prosthetic heart valve into a delivery device may include a body extending in a longitudinal direction between a proximal end and a distal end, an extension on the distal end of the body, and a slot extending through the extension from a free end of the extension toward the distal end of the body. The body may include a lumen extending between the proximal end and the distal end, the body lumen having a first diameter. The extension may have a lumen coaxial with the body lumen, the extension lumen having a second diameter less than the first diameter so as to define a shelf surface between the proximal end of the body and the free end of the extension.

摘要： A prosthetic heart valve having an inflow end and an outflow end includes a collapsible and expandable stent having a plurality of commissure features, a plurality of first struts and a plurality of second struts. The plurality of first struts define a substantially cylindrical portion and the plurality of second struts have first ends attached to the cylindrical portion and free ends projecting radially outward from the cylindrical portion and configured to couple to adjacent heart tissue to anchor the stent. A collapsible and expandable valve assembly disposed within the stent has a plurality of leaflets coupled to the commissure features.

摘要： A prosthetic heart valve having an inflow end and an outflow end includes a stent having a collapsed condition, an expanded condition, and a plurality of cells arranged in circumferential rows. The stent may include one or more securement features. One securement feature may be an anchor arm having a body portion and a free end extending from the body portion, the body portion being coupled to a perimeter of one of the plurality of cells, with the free end extending toward the inflow end in an expanded condition of the anchor arm. Another securement feature may include a flange formed of a braided mesh and having a body portion coupled to the stent and a flared portion adjacent the inflow end of the prosthetic heart valve. A valve assembly is disposed within the stent and has a plurality of leaflets.

摘要： 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.

摘要： A prosthetic heart valve for replacing a native valve includes a collapsible and expandable stent extending between a proximal end and a distal end. The stent includes an annulus section adjacent the proximal end and having a first diameter, a plurality of first struts forming cells, and a plurality of second struts connected to the annulus section and forming a plurality of deflecting cells expandable to define a second diameter larger than the first diameter. A valve assembly is disposed within the stent and a cuff is coupled to the stent and covers the plurality of deflecting cells.
