1. A catheter system for modifying an annulus of a heart valve to reduce regurgitation of blood flow through the valve, comprising:
- a catheter having at least one lumen, first and second fasteners coupled together by a flexible tensile member and adapted to be secured to heart tissue proximate the annulus, and a rod movable between a compact state within said lumen and an expanded state outside of said lumen, said first and second fasteners further coupled to said rod such that said first fastener is movable along the rod relative to said second fastener by applying tension to said flexible tensile member.

6. A catheter system for modifying an annulus of a heart valve to reduce regurgitation of blood flow through the valve, comprising:
-
first, second and third fasteners adapted to be secured to the annulus, first, second and third flexible tensile members respectively connectable to said first, second and third fasteners, and a generally V-shaped valve support member having a pair of legs movable between a compact state suitable for carrying said valve support member within a catheter and an expanded state in which said legs are more separated, a free end of each leg including respective first and second eyelets receiving said first and second flexible tensile members and an apex between said pair of legs including a third eyelet receiving said third flexible tensile member. - View Dependent Claims (7, 9)
