A devicefor gathering tissue in a patient includes an elongated catheterand a capture assemblyat a distal portion of the catheter. The capture assembly has a closed sideand a doorrotatable between an open condition and a closed condition. The closed sideof the capture assemblyand the doorin the closed condition may collectively define a tissue capturing compartment. Movement of the doorfrom the open condition to the closed condition adjacent the tissue may capture a portionof the tissue in the tissue capturing compartment. A clip may then be applied from the capture assemblyto the captured tissueto hold the tissue substantially in a gathered configuration.

Apparatus and method for heart valve repair

A devicefor repairing mitral valve leafletsincludes a jaw mechanismthat may be positioned adjacent a mitral valve leaflet. The jaw mechanismmay move between an open position and a closed position by pivoting a first jaw relativeto a second jaw. The first jawmay include a rivetthat may move from a stored position to an application position projecting away from the first jawwhen the jaw mechanismis moved from the closed to the open position. Closing the jawsabout a valve leafletcauses the rivetto pierce the leaflet. The jaw mechanismmay then be rotated to wind the leafletthereabout and again pierce the leaflet. The rivetmay then be released from the jaw mechanismand the deviceremoved from the patient.

A method of gathering tissue of a heart valve leafletmay include inserting an elongated catheter assemblyto a position adjacent the heart valve leaflet, the catheter assembly including a capture tooland a tissue support member. The capture tooland the tissue support membermay each be independently moveable between a retracted position and an extended position. Partially retracting the capture toolwith the tissue support memberin the extended position gathers tissueof the heart valve leafletbetween the capture tool and the tissue support member. A clipmay then be applied from the catheter assemblyto the gathered tissueto hold the tissue substantially in a gathered configuration.

A device for repair of a heart valve leaflet includes an elongated catheter assembly having a proximal end and a distal end, and a tip at the distal end of the catheter assembly. A capture mechanism having a first free end and a second free end is rotatably coupled to a distal end of the tip. A plication mechanism has an open configuration and a closed configuration, and extends between the first free end and the second free end of the capture mechanism when in the open configuration. The device may also include a clip housing at a proximal end of the tip configured to hold a clip therein.

Transfemoral mitral valve repair delivery device

A devicefor gathering tissue in a patient includes an elongated catheterand a capture assemblyat a distal portion of the catheter. The capture assembly has a closed sideand a doorrotatable between an open condition and a closed condition.

A device for transcatheter gathering of tissue of a heart valve leaflet may include an elongated tube extending in a longitudinal direction and a capture tool moveable in the elongated tube between a retracted position and an extended position. The elongated tube may have at least one slot extending generally in the longitudinal direction from a distal end of the elongated tube. The at least one slot may have an open end at the distal end of the elongated tube and a closed end remote therefrom. The capture tool may be operable to gather tissue of the heart valve leaflet into the at least one slot. The gathered tissue may have a pleated configuration.
