System for improving the function of a heart valve

1. A heart valve annuloplasty system for improving the function of a heart valve comprising:

a first loop-shaped support, which is configured to abut a first side of said heart valve,

a second loop-shaped support, which is configured to abut a second side of said heart valve opposite to said first side such that said heart valve is trapped between said first looped-shaped support and said second loop-shaped support;

said second loop-shaped support having an outer boundary which is greater than an outer boundary of said first loop-shaped support

said first loop-shaped support and said second loop-shaped support each being formed from a magnetic material, such that, when subjected to an externally applied magnetic field, said first loop-shaped support and said second loop-shaped support, when arranged on radially displaced opposing sides of the heart valve, are attracted to each other by said magnetic field for holding said first loop-shaped support and said second loop-shaped support on opposing sides of the heart valve.

2. The system according to claim 1 , comprising at least one fastener for connecting said first loop-shaped support and said second loop-shaped support together when arranged on opposite sides of said heart valve.

3. The system according to claim 2 , wherein the first loop-shaped support and said second loop-shaped support comprise receiving members for receiving said at least one fastener.

4. The system according to claim 2 , wherein said at least one fastener is disposed on said first loop-shaped support and the second loop-shaped support includes receiving members for receiving said at least one fastener.

5. The system according to claim 2 , wherein said at least one fastener has a sharp projection for penetrating tissue of said heart valve.

6. The system according to claim 2 , wherein said at least one fastener has an end of an expanded diameter.

7. The system according to claim 2 , wherein said at least one fastener has a curved portion.

8. The system according to claim 1 , wherein at least one of said first loop-shaped support and said second loop-shaped support is open.

9. The system according to claim 8 , wherein said at least one of said first loop-shaped support and said second loop-shaped supports is C-shaped.

10. The system according to claim 1 , wherein said first loop-shaped support and the second loop-shaped supports are separate and distinct units.

11. The system according to claim 1 , wherein the first loop-shaped support is continuous with the second loop-shaped support.

12. The system according to claim 1 , wherein said magnetic field is operative for being turned off.

13. A heart valve annuloplasty system for improving the function of a heart valve comprising:

a first curve-shaped support, which is configured to contact a first side of said heart valve,

a second curve-shaped support, which is configured to contact a second side of said heart valve opposite to said first side such that said heart valve is trapped between said first curve-shaped support and said second curve-shaped d support;

said second curve-shaped support having an outer boundary which is greater than an outer boundary of said first curve-shaped support

said first curve-shaped support and said second curve-shaped support each being formed from a magnetic material, such that, when subjected to an externally applied magnetic field, said first support and said second support, when arranged on radially displaced opposing sides of the heart valve, attract said first curve-shaped support and said second curve-shaped support towards each other for holding said first curve-shaped support and said second curve-shaped on opposing sides of the heart valve;

wherein said applied magnetic field is operative for being turned off.
