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.

Valve prosthesis frames

A system for percutaneous delivery of a stented prosthetic heart valve. The system includes a delivery device with a self-expanding prosthetic heart valve attached thereto and a delivery sheath with an opening on a distal end thereof. The delivery sheath includes a funnel on a proximal end thereof. The delivery device is inserted into the funnel of the delivery sheath. As the delivery device is advanced into the funnel, the expanded heart valve is compressed by the shape of the funnel into a crimped arrangement. The delivery device further advances the heart valve distally within the delivery sheath past the delivery sheath opening. The delivery device is advanced relative to the delivery sheath in transitioning the heart valve from a crimped arrangement to the expanded and deployed arrangement.

Transcatheter prosthetic heart valve delivery system and method

A prosthesis can include a collapsible, reexpandable frame having 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.

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.

Systems and methods for loading a valve prosthesis onto a catheter

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.
