Abstract
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.
Claims20
An annuloplasty prosthesis for repair of a cardiac valve annulus by affecting the dimensions or shape of the valve annulus, so as to improve performance of the cardiac valve, the prosthesis comprising:
- a ring element having a longitudinal axis, a curved portion, and a generally straight portion, the ring element configured to have a shape generally corresponding to a desired shape of a normal cardiac valve annulus;
- and
- a sheath covering at least a portion of the ring element;
- wherein the ring element defines a plurality of apertures each having a characteristic selected to effect the flexibility of the annuloplasty prosthesis.
An annuloplasty prosthesis comprising a ring element having a size and a shape generally corresponding to a cardiac valve annulus, the ring element including a plurality of apertures for controlling the flexibility of the annuloplasty prosthesis.
A method of forming an annuloplasy prosthesis, the method comprising:
- forming a plurality of apertures in a laminar or tubular element, including configuring the apertures such that the laminar or tubular element has a desired non-uniform flexibility along its length;
- and
- forming the laminar or tubular element into a ring element having a shape generally corresponding to a shape of a natural cardiac valve annulus.
