DEVICE AND METHOD FOR THE SURGICAL TREATMENT OF ISCHEMIC MITRAL REGURGITATION

摘要

A device for the treatment of ischemic mitral regurgitation of a damaged left ventricle having an opposing papillary muscles displaced laterally or axially relative to the mitral annulus. The device includes a lateral limb configured to extend between opposing papillary muscles of a left ventricle and first and second axial limbs extending from spaced points on the lateral limb to form an essentially U-shaped configuration. The first and second axial limbs are configured to extend between the lateral limb and a mitral annulus. A method for the treatment of mitral regurgitation comprises extending a first segment of the lateral limb of the device across opposing sides of a ventricle near opposing papillary muscles. The segment of the first lateral limb is shortened as needed to put the first and second papillary muscles into a substantially normal lateral position relative to the mitral annulus and the length of the segment of the first lateral limbs is fixed. The method further includes extending a segment of the first axial limb between the lateral limb and the mitral annulus and extending a segment of the second axial limb between the lateral limb and the mitral annulus. The first and second axial limb segments are then shortened, as needed, to put opposing papillary muscles into a substantially normal axial position relative to the mitral annulus and the lengths of the segments of the first and second axial limbs are fixed.
