## 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

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

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.

### Claim 4 (depends on 3)

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.

### Claim 5 (depends on 1)

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