US Patent 8632588 Mitral valve cerclarge annuloplasty appratus and method thereof

A mitral cerclage annuloplasty apparatus comprises a tissue protective device and a cap device having a cerclage suture disposed within a first protective tube and a second protective tube, the proximal portions of the two tubes being attached side-by-side longitudinally to define a stem portion, the distal portions of the two tubes being separated thereafter, and a cap device that covers the stem portion wherein the stem portion and the cap device interlock, so that once the cerclage suture is knotted on the outer surface of the cap device, cap device can be pulled outwardly to enhance and maintain tension applied to the mitral annulus thus successfully treating the mitral regurgitation.
