    Abstract: A prosthetic heart valve may include a stent having an inflow end, an outflow end, a collapsed condition, and an expanded condition. The prosthetic valve may also include a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets. The prosthetic valve and/or stent may include features to anchor the prosthetic valve to a native valve annulus and to seal the prosthetic valve with respect to the native valve annulus, such as planar and/or nonplanar annular sealing members coupled to ends of the stent. The stent may include one or more circumferential rows of anchor members or hooks extending radially outwardly from the stent. These hooks may be configured to extend in a particular direction when the stent is in the collapsed condition to facilitate resheathing of the stent if, upon deployment, a user determines the prosthetic heart valve is not positioned optimally.

    Abstract: 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.

    Abstract: A prosthetic heart valve having an inflow end, an outflow end and a longitudinal axis extending from the inflow end to the outflow end includes a collapsible and expandable stent including a plurality of cells arranged in at least one row extending around a circumference of the stent. The stent further includes at least one engaging arm joined to one of the cells adjacent the outflow end and having a free end extending toward the inflow end, the engaging arm being movable between a loaded condition in which the engaging arm is oriented substantially parallel with the longitudinal axis of the stent, a partially-released condition in which the engaging arm forms a first angle with the longitudinal axis of the stent, and a fully-released condition in which the engaging arm forms a second angle with the longitudinal axis of the stent, the first angle being larger than the second angle.

    Abstract: A transcatheter method of gathering tissue of a heart valve leaflet may include inserting an elongated catheter assembly to a position adjacent the heart valve leaflet, the catheter assembly including a capture tool moveable between a retracted position and an extended position, a tissue support, and a clamping member moveable between an open position and a closed position. The capture tool may be partially retracted to gather tissue of the heart valve leaflet between the tissue support and the clamping member. The clamping member may then be moved from the open position toward the closed position so as to clamp a substantial portion of the gathered tissue of the heart valve leaflet between the tissue support and the clamping member. Subsequently, a clip may be applied from the catheter assembly to the clamped tissue so as to hold the clamped tissue substantially in a gathered configuration.

    Abstract: An apparatus for applying liquid pressure to resected tissue may include a fixture, a papillary assembly coupled to the fixture and having first and second spaced apart papillary attachment elements, and a resected mitral valve attached to the fixture. The fixture may have a first chamber, a second chamber, and an internal panel extending between the first and second chambers. The resected mitral valve may be attached to the internal panel and may have a posterior leaflet, an anterior leaflet, and tendinae chordae. The tendinae chordae may each be attached at a first end to the posterior leaflet or the anterior leaflet and at a second end to one of the papillary attachment elements. A first group of the tendinae chordae may be attached to the first papillary attachment element, and a second group of the tendinae chordae may be attached to the second papillary attachment element.
