    Abstract: An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration includes an annular frame including a plurality of angled strut members, a plurality of leaflets disposed within the frame and secured to the frame, and a skirt member secured to the frame. The skirt member is disposed about an edge portion of a leaflet of the plurality of leaflets, and the skirt member includes a plurality of extension portions wrapped around at least one strut member. A cord member is threaded through at least a portion of the plurality of extension portions in a direction along an axis of the at least one strut member to secure the skirt member to the at least one strut member.

    Abstract: Disclosed herein is a method of crimping a prosthetic heart valve using a compact crimping mechanism. The crimping mechanism includes a plurality of jaws configured for coordinated inward movement toward a crimping axis to reduce the size of a crimping iris around a stented valve. A rotating cam wheel acts on the jaws and displaces them inward. A number of Cartesian guide elements cooperate with the jaws to distribute forces within the crimping mechanism. The guide elements are located between the crimping jaws and an outer housing and are constrained by the outer housing for movement along lines that are tangential to a circle centered on the crimping axis. The guide elements engage at least some of the crimping jaws while the rest are in meshing engagement so as to move in synch. An actuation mechanism includes a lead screw, carriage assembly and a linkage to rotate the cam wheel with significant torque.

    Abstract: A medical assembly can include a radially expandable prosthetic heart valve and a delivery apparatus. The delivery apparatus can include a handle, an actuation member, and a force limiting mechanism within the handle including a pivot arm coupled to a base portion. The actuation member can apply a proximally directed force to the prosthetic valve to cause the valve to expand. The actuation member can be coupled to the pivot arm such that a force applied to the actuation member causes the pivot arm to pivot. The force limiting mechanism can pinch the actuation member between the pivot arm and the base portion when the force applied to the actuation member exceeds a predetermined force to prevent proximal movement of the actuation member and can allow proximal movement of the actuation member to produce radial expansion of the prosthetic valve when the force applied is less than the predetermined force.
