Method and apparatus for attaching a valve prosthesis
First Claim
1. A device to deliver a valve prosthesis to a target tissue, the device comprising:
- at least one anchor;
at least one guide wire coupled to the anchor;
a fastener housing;
a first set of fasteners in said fastener housing, wherein said fasteners are movable from a first position to a second, tissue engagement position; and
a second set of fasteners housed in said anchor to attach the anchor to the tissue, wherein the fasteners are movable from a first position to a second, tissue engagement position;
wherein said guide wire is slidably received in the fastener housing and has a length sufficient to extend from the fastener housing to the target tissue site, said guide wire used to direct the fastener housing into place.

9. A method for attaching a valve prosthesis to a target tissue, the method comprising:
-
attaching a plurality of anchors each having a guide wire to the target tissue;
slidably advancing a delivery device having a fastener housing along the guide wires, wherein said fastener housing has grooves or slots for receiving the guide wires;
positioning the delivery device so that fasteners inside the fastener housing will engage the target tissue when the fasteners are deployed; and
clipping the guide wires so that the anchors can remain embedded in tissue when the guide wires are removed. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
