Medical system and method for remodeling an extravascular tissue structure

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 at least part way between the proximal end and the distal end, the first side having a fixed axial length, and the second side having an adjustable axial length;
• 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.

A multizone vascular implant, comprising:

• a tubular body having a proximal end region and a distal end region, each of the proximal and distal end regions dimensioned to reside completely within the vascular system, the tubular body being movable from a first configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus proximate the coronary sinus;
• a plurality of transverse voids on the tubular body to permit flexing in at least one plane;
• at least a first, proximal zone and a second, distal zone on the body;
• a first control wire for imparting curvature in the first zone;
• and
• a second control wire for imparting curvature in the second zone.

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 dimensioned to reside completely within the vascular system, the elongate body being movable from a first configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus proximate the coronary sinus;
• a forming element attached to the elongate body for manipulating the elongate body from the first transluminal configuration to the second remodeling configuration;
• and
• a lock for retaining the body in the second configuration;
• wherein the elongate body comprises a tube having a plurality of transverse slots therein;
• and,
• wherein the forming element extends through the elongate body from the proximal end region to the distal end region.
