Abstract
A leaflet repair device for a heart valve of a human heart comprises an implantable leaflet with a coaptation edge; a repair chord connected at one end to near the coaptation edge; a chord anchor for anchoring the repair chord to native structure of the human heart; and at least one annulus anchor for anchoring the leaflet to native structure of the human heart. In at least one embodiment, the leaflet repair device may overlap a diseased, prolapsed, or otherwise inferior leaflet that is not creating proper coaptation with a mating leaflet.
Claims20
A heart valve repair system comprising:
- an implantable leaflet having a coaptation edge and an annulus edge;
- a chord for connecting said coaptation edge to a native structure of the heart, said chord having a proximal and a distal end;
- a fixation mechanism associated with said chord for attaching said distal end of said chord to said native structure of said heart;
- at least one annulus attachment device for securing said annulus edge of said implantable leaflet to an annulus of said heart valve.
A method for repairing a valve in a heart comprising:
- obtaining a replacement leaflet having an annulus edge and a coaptation edge;
- delivering said replacement leaflet to a malfunctioning heart valve;
- attaching said annulus edge of said replacement leaflet to an annulus of said malfunctioning heart valve;
- connecting said coaptation edge of said replacement leaflet to a native structure of said heart.
A kit for treating a malfunctioning valve of a heart comprising;
- a steerable guide catheter;
- a delivery catheter;
- a replacement valve leaflet configured for delivery in said delivery catheter through said steerable guide catheter;
- a plurality of chords for securing said leaflet into tissue associated with said malfunctioning valve;
- a plurality of anchor mechanisms associated with said plurality of chords;
- a pusher for deploying said chords and deploying said replacement leaflet.
