System for improving the function of a heart valve

摘要

A device for improving the function of a heart valve comprises a first loop-shaped support, which is configured to abut a first side of the heart valve, and a second loop-shaped support, which is configured to abut a second side of the heart valve opposite to said first side, whereby a portion of the valve tissue is trapped between the first and second supports. An outer boundary of the second support is greater than an outer boundary of the first support.

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.
