Abstract
A medical device (1210) comprises a generally cylindrical treatment element (1220) for location between a pair of valve leaflets (1212) situated between an atrium (1214) and a ventricle (1216) of a heart. The treatment element (1220) supports the valve leaflets (1212) at the region of co-aptation of the valve leaflets (1212) and occludes the valve opening to resist fluid flow in the retrograde direction through the valve opening. The device (1210) comprises a support (1222) to support the treatment element (1210) at the region of co-aptation of the valve leaflets (1212). The support has an anchor (1224) and a tether (1226), the tether (1226) being provided at the end of a guide wire (1228) which is initially utilised in the percutaneous insertion of the treatment element (1220). The anchor (1224) is secured, in use, to a septal wall (1230), while the guide wire (1228) exits the atrium (1214) through a vein adjacent a rear wall (1224) thereof. The treatment element (1220) includes a remotely actuatable clamp therein, in order to allow the treatment element (1220) to be secured to the guide wire (1228) or the tether (1226).

222. A method of treating a valve using a treatment device, the treatment device comprising a treatment element, a treatment wire and an anchor element, the method comprising the steps of:
-
advancing a procedural catheter into the atrium;
advancing the treatment wire through the procedural catheter and passing the distal end of the treatment wire across the valve;
anchoring a distal end of the treatment wire to a wall of the ventricle;
expanding the treatment element at the desired region; and
terminating the proximal end of the wire beneath the skin of the patient. - View Dependent Claims (223, 224, 226, 227, 228, 229, 230, 231, 232, 233, 234, 235, 236, 237, 238, 239, 240, 241, 242, 243)
