Abstract:
1. A device for repairing a cardiac valve, said device comprising: an interventional catheter adapted to pass from the remote vasculature of a patient to a position within a heart of the patient adjacent to the cardiac valve; and a capture device on the interventional catheter comprising at least one distal element coupled to the catheter, wherein the distal element is protrudable radially outward and is adapted to press against a downstream surface of at least one leaflet, wherein the interventional catheter further comprises at least one fixation tool for fixing the valve leaflet to a second valve leaflet, the fixation tool comprising a penetrating device which has a suture and an anchor coupled with the suture, wherein the anchor has a first profile adapted to be housed at least partially within the penetrating device and a second profile larger than the first profile, the second profile adapted to engage the downstream surface of the at least one leaflet thereby anchoring the suture to the at least one leaflet, wherein the anchor comprises a tubular structure adapted to radially expand upon delivery of the anchor through the valve leaflet, and wherein the tubular structure expands radially outward when axially compressed.
