3. A system for modifying an annulus of a heart valve to reduce regurgitation of blood through the valve, comprising:
-
a first catheter, a first magnet coupled with said first catheter in such a manner that said first catheter is operative to deliver said first magnet adjacent to the annulus, a second catheter, a second magnet coupled with said second catheter in such a manner that said second catheter is operative to deliver said second magnet adjacent to the annulus, and a fastener delivery device coupled to at least one of said first and second catheters and configured to secure a first fastener to the annulus. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A catheter adapted to be a guide element placed within a vessel, comprising:
-
a distal support portion, and first and second magnets carried on said distal support portion, said first and second magnets positioned in spaced apart relation such that a gap is formed between said first and second magnets and repelling poles face each other, whereby a circumferential virtual magnetic pole emanates around the gap between said first and second magnets.
