Abstract:
Devices and methods for delivering a sealing element post-implantation of valve prosthesis that functions to occlude or fill gaps present between the valve prosthesis and the native valve tissue, thereby reducing, minimizing, or eliminating leaks there through. In a first method, an injectable material is placed within a native valve sinus to form a sealing element that presses native valve leaflets against an outer surface of a heart valve prosthesis. In a second method, an injectable sealing material or a preformed annular sealing component is positioned between the outer surface or perimeter of a heart valve prosthesis and native heart valve tissue. In a third method, a preformed sealing element or component is placed within a heart valve prosthesis to press the prosthesis against native valve tissue.
Abstract:
A crimping tool includes a housing portion defining a funnel segment and a suture locking mechanism positioned to lock sutures therein. One or more sutures can be coupled with a prosthesis and secured to the suture locking mechanism. The suture locking mechanism can be operated to draw the prosthesis through the funnel segment.

Abstract:
A medical device loading system can comprise a first housing, a second housing, and a plate. The first housing comprises a first open end, a first tapered inner surface, and a second open end. The second housing comprises a third open end, a second tapered inner surface, and a fourth open end. The second housing can define a slot between the second tapered surface and the third open end. The plate can be configured to be slidably received within the slot. The loading system can further comprise a first elongated member and a second elongated member.

Abstract:
A prosthesis can include a collapsible, reexpandable frame comprising first, second, and third sets of struts that define first and second rows of expandable cells. In some embodiments, the struts of the first, second, and third set of struts can be tapered. In some embodiments, the frame can include an intermediate section and an inflow section that is proximal to the intermediate section. The inflow section can include a concave saddle portion that is adjacent the intermediate section, and an outwardly flared portion.
