摘要

A prosthesis for annuloplasty comprising a laminar or tubular element having a plurality of apertures along at least one portion. Preferably, the shape, dimensions, and arrangements of the apertures in this prosthesis are chosen in such a way as to give the prosthesis a differentiated flexibility in dependence on the location and direction of application of an external stress.
