Tissue shaping device
First Claim
1. A mitral valve therapy device configured for deployment within a coronary sinus, the therapy device comprising an expandable distal anchor, a proximal anchor, and an elongate body extending therebetween, the elongate body defining a longitudinal axis of the therapy device, the expandable distal anchor comprising:
- a flexible elongate member and a securing member for securing a first and second end of the flexible elongate member therein at a distal end of the securing member, the securing member generally aligned with the elongate body along the longitudinal axis, a first segment of the flexible elongate member extending from a distal end of the distal anchor to a proximal end of the distal anchor to engage the elongate body proximal the distal end of the elongate body, and a second segment of the flexible elongate member extending from where the first segment engages the elongate body to the distal end of the distal anchor, the first segment crossing the second segment at a location between the distal and proximal ends of the distal anchor, the distal anchor further having a collapsed configuration for delivery into the coronary sinus within a catheter and an expanded configuration for anchoring the distal anchor in the coronary sinus, the location being positioned radially outward from the securing member when the distal anchor is in the expanded configuration.

Abstract
An anchor anchors a therapeutic device having an elongated body within a body lumen. The anchor includes a fixation member carried on the device which is adjustable from a first configuration that permits placement of the device in the body lumen to a second configuration that anchors the device within the body lumen. The anchor further includes a lock that locks the fixation member in the second configuration. The fixation member may be locked in any one of a plurality of intermediate points between the first configuration and a maximum second configuration.
