Abstract
A prosthetic mitral valve comprising a flexible frame comprising an annular base and a pair of diametrically-opposed struts extending downwardly from the annular base; a sewing ring mounted to the annular base for securing the prosthetic mitral valve in an annulus vacated by a native mitral valve; a pair of leaflets mounted to the annular base and the pair of diametrically-opposed struts; and a pair of coupling sutures configured to extend from the sewing ring, down the pair of diametrically-opposed struts, and across a left ventricle for securing the prosthetic mitral valve to papillary muscles.
Claims21
A prosthetic mitral valve comprising:
- a flexible frame comprising an annular base and a pair of diametrically-opposed struts extending downwardly from the annular base;
- a sewing ring mounted to the annular base for securing the prosthetic mitral valve in an annulus vacated by a native mitral valve;
- a pair of leaflets mounted to the annular base and the pair of diametrically-opposed struts;
- and
- a pair of coupling sutures configured to extend from the sewing ring, down the pair of diametrically-opposed struts, and across a left ventricle for securing the prosthetic mitral valve to papillary muscles.
A method for improving mitral valve function, the method comprising:
- providing a prosthetic mitral valve comprising:
- a flexible frame comprising an annular base and a pair of diametrically-opposed struts extending downwardly from the annular base;
- a sewing ring mounted to the annular base for securing the prosthetic mitral valve in an annulus vacated by a native mitral valve;
- a pair of leaflets mounted to the annular base and the pair of diametrically-opposed struts;
- and
- a pair of coupling sutures configured to extend from the sewing ring, down the pair of diametrically-opposed struts, and across a left ventricle for securing the prosthetic mitral valve to papillary muscles;
- removing a native mitral valve;
- securing the pair of coupling sutures to the papillary muscles;
- securing the sewing ring at the seat of the native mitral valve;
- tensioning the pair of coupling sutures so as to set the tension between the annular base and the papillary muscles;
- and
- securing the pair of coupling sutures to the sewing ring.
