MITRAL AND VENTRICULAR GEOMETRY RESTORATION SYSTEMS AND METHODS

摘要

Apparatuses and method of using them, for restoring and reshaping the mitral valve annulus and reduce or restore the lengthwise geometry of the heart. These apparatuses may include two or more support chords each having an anchor at the distal end for connecting to a valve annulus, and an elongate length. The support chords may be held within a thin delivery cannula. Also include a bendable/conformable apical cradles to which the proximal end of the chords may be attached. The attachment to the cradle or sling member may be adjustable, so that the length of the chords may be adjusted from outside of the heart later. Attaching the support chords to the valve annuls and anchoring on either side of the apex region of the heart may reshape both the mitral valve and the ventricle length.

主权项

1. A system for reshaping the geometry of a diseased heart, the system comprising:
a cradle for supporting an apical portion of the heart, the cradle having a central portion for supporting the apical portion of the heart, a first end for supporting a first side of the heart, and a second end for supporting a second side of the heart, the cradle having a first reinforced structure disposed on the first end and a second reinforced structure disposed on the second end, wherein the cradle is made from a flexible material; a first support chord having a distal end and a proximal end, the distal end of the first support chord comprising a first anchor, the proximal end of the first support chord configured to be secured to the first reinforced structure; and a second support chord having a distal end and a proximal end, the distal end of the second support chord comprising a second anchor, the proximal end of the second support chord configured to be secured to the second reinforced structure.
