Abstract
Described embodiments are directed toward centrally-opening leaflet support devices having a frame and one or more support leaflets coupled to the frame forming a hinge where coupled. The described support leaflets have one or more stiffer regions that facilitate the function of a support leaflet to decrease or prevent prolapse of a native valve leaflet. Methods of making and using such valve devices are also described amongst others.
Claims21
A leaflet support device, comprising:
- a first frame defining a base, a tubular member, and a first frame central opening;
- a second frame defining a flat ring, a second frame central opening, and an inner portion, the second frame coupled to the base of the first frame;
- a support leaflet including a leaflet attachment region coupled to the base of the first frame and a leaflet free edge opposite the leaflet attachment region, the support leaflet configured to transition between an open position and a closed position, the inner portion of the second frame operable to limit movement of the support leaflet when transitioning from the open position to the closed position.
