1. A method for repairing a heart valve, said heart valve being comprised of valve tissue including an annulus and a plurality of leaflets for allowing and preventing blood flow, said method comprising:
delivering a medical device comprising a first loop-shaped support and a first flange unit extending radially from the said first loop-shaped support to the heart valve, positioning said first loop-shaped support such that it abuts a first side of the heart valve, positioning said first flange unit such that it abuts said annulus, sealing said first flange unit against said annulus with a sealing surface of said first flange unit, fixating said device by attaching said first flange unit to said annulus wherein: said first flange unit extends radially downward at an angle α of between 30° and 60° to a diametric plane of said first loop-shaped support before said positioning to abut the first side of the heart valve and positioning said first flange unit such that it abuts said annulus comprises conforming said first flange unit to said annulus and thereby changing the shape of said first flange unit to extend upwardly from said annulus.
