Abstract
A prosthetic heart valve includes a collapsible and expandable stent having an outflow end and an inflow end, a plurality of commissure features attached to the stent, a plurality of anchoring features disposed on legs of the stent, the plurality of anchoring features being coupleable to a delivery device for repositioning, and a valve assembly disposed within the stent. The anchoring features may be configured to attach to heart tissue to help secure the prosthetic heart valve in an operating position.
Claims10
A prosthetic heart valve, comprising:
- a collapsible and expandable stent having an outflow end and an inflow end;
- a plurality of legs having an attached end coupled to the outflow end of the stent and a free end unattached to the stent, each of the plurality of legs extending away from the outflow end and being biased to move from a substantially straight configuration to a curled configuration such that in the straight configuration a distance between the attached end of the leg and the free end of the leg is greater than a distance between the attached end of the leg and the free end of the leg in the curled configuration, the plurality of legs being capable of grasping heart tissue in the curled configuration;
- a plurality of commissure features disposed on the stent;
- a plurality of closed, circular anchoring features configured to be hooked and unhooked to a delivery device to position the stent within a native valve annulus, each anchoring feature being disposed on the free end of a respective single one of the plurality of legs;
- and
- a collapsible and expandable valve assembly disposed within the stent.
