Transluminal mitral annuloplasty with active anchoring
First Claim
Patent Images
1. A method of performing transluminal mitral annuloplasty, comprising the steps of:
- providing a catheter, having a prosthesis thereon;
inserting the catheter into the venous system;
transluminally advancing the prosthesis into the coronary sinus;
advancing at least one tissue anchor from a retracted position to an extended position; and
manipulating a component of the prosthesis to cause the prosthesis to exert force on the mitral valve annulus.

Abstract
A medical apparatus and method for remodeling a mitral valve annulus adjacent to the coronary sinus includes an elongate body having a proximal end and a distal end. The elongate body is movable from a first, flexible configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus.

24. A method of providing a therapeutic compressive force against a tissue structure which is adjacent to a vessel wall, the vessel wall having a first side and a second side, comprising the steps of positioning a device in the vessel;
- advancing a proximal tissue anchor from the device into the first side;
advancing a distal tissue anchor from the device into the first side; and
manipulating a forming element within the device to cause the device to exert a force against the first side of the wall of the vessel in between the proximal anchor and the distal anchor. - View Dependent Claims (25, 26, 27, 28)

29. A method of performing annuloplasty of the mitral valve comprising positioning a prosthesis in the coronary sinus;
- rotating a first portion of the device with respect to a second portion of the device to cause the device to bend into an arcuate configuration having a proximal concavity and a distal concavity both concave toward the mitral valve and a central concavity concave away from the mitral valve, to provide a compressive force on the mitral valve annulus; and
securing the device in the arcuate configuration within the coronary sinus. - View Dependent Claims (30, 31, 32, 33, 34)

35. A medical apparatus for remodeling a mitral valve annulus adjacent to the coronary sinus, comprising:
- an elongate body, having a proximal end region and a distal end region, each of the proximal and distal end regions configured to move between a first, flexible configuration for transluminal delivery to at least a portion of the coronary sinus and a second remodeling configuration in which each of the proximal and distal end regions forms a curve which is open in the direction of the mitral valve; and
a forming element for manipulating the elongate body between the first transluminal configuration and the second remodeling configuration. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. An implant for positioning within a patient, comprising:
- an elongate flexible body having a proximal end and a distal end, and a longitudinal axis extending therebetween, and first and second opposing sides extending along the implant body;
the first side having at least one fixed axial length section, and the second side having at least one fixed axial length section, axially offset from the fixed axial length section on the first side;
at least a first forming element extending through the body to a distal point of attachment to the body; and
a detachable coupling on a proximal portion of the body, for removably attaching the body to a deployment catheter;
wherein manipulation of the first forming element deflects at least a first portion of the body away from the longitudinal axis. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54)
