Abstract

An implant delivery system comprising a catheter including at least one lumen, an implant configured to be received in the lumen, and a latching mechanism configured to be received in the implant. The latching mechanism may be configured to releasably couple the implant to a delivery wire and to transmit a torque through the delivery wire to cause at least a portion of the implant to rotate. The an implant may comprise a shaft, a spacer configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through the heart valve in a closed position, a garage configured to couple the spacer to a first end region of the shaft, and at least one anchor mechanism. The garage may define a cavity configured to receive the latching mechanism and to increase rotational and translational stability of the latching mechanism.

Claims

1. An implant comprising:

a shaft;

a resiliently deformable spacer configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through said heart valve when said heart valve is in a closed position;

a latching mechanism having a first latching pin and a second latching pin, the second latching pin to releasably couple with the first latching pin of said latching mechanism;

a garage configured to couple said spacer to a first end region of said shaft, said garage defining a cavity configured to receive said first latching pin of said latching mechanism; and

at least one anchoring mechanism coupled to a second end region of said shaft.

2. The implant of claim 1, wherein said anchor mechanism comprises a cavity configured to at least partially receive a helical screw, said helical screw coupled to a first end of an anchoring wire, wherein a second end of said helical screw is coupled to said first latching pin.

3. The implant of claim 2, wherein said anchoring mechanism further comprises a threaded region secured within said cavity, said threaded region having a thread pitch and size substantially corresponding to a first threaded region of said helical screw.

4. The implant of claim 3, wherein said helical screw further comprises a second threaded region disposed proximate said anchoring wire, said second threaded region configured to not pass through said threaded insert.

5. The implant of claim 1, wherein said anchoring mechanism further comprises a pledget configured to stimulate ingrowth of tissue.
