Percutaneous mitral annuloplasty and cardiac reinforcement
First Claim
Patent Images
1. An implant for positioning within a vessel to influence tissue outside of the vessel, comprising:
- an elongate, flexible body, having a proximal end and a distal end, each of the proximal and distal ends dimensioned to reside completely within the vascular system; and
a forming element attached within the body, the forming element comprising a polymeric strand;
wherein rotation of at least a portion of the forming element with respect to the body changes the shape of the body from an implantation configuration to a remodeling configuration, wherein at least a portion of the forming element remains attached to the body following implantation.

Abstract
A mitral annuloplasty and left ventricle restriction device is designed to be transvenously advanced and deployed within the coronary sinus and in some embodiments other coronary veins. The device places tension on adjacent structures, reducing the diameter and/or limiting expansion of the mitral annulus and/or limiting diastolic expansion of the left ventricle. These effects may be beneficial for patients with dilated cardiomyopathy.

27. An implant for positioning within a vessel to influence tissue outside of the vessel, comprising:
-
an elongate, flexible body, having a proximal end and a distal end, each of the proximal and distal ends dimensioned to reside completely within the vascular system; and
a forming element attached within the body, the forming element comprising a screw, at least partially within the flexible body;
wherein rotation of at least a portion of the forming element with respect to the body changes the shape of the body from an implantation configuration to a remodeling configuration, wherein at least a portion of the forming element remains attached to the body following implantation. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
