TISSUE SHAPING DEVICE

摘要

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.

1. A method of performing mitral valve annuloplasty on a patient's heart comprising:
percutaneously delivering a mitral valve device to a coronary sinus in a collapsed delivery configuration within a catheter, the mitral valve device comprising a first expandable anchor, a second expandable anchor, and an elongate body extending therebetween, the elongate body defining a longitudinal axis of the mitral valve device; deploying the first expandable anchor from the catheter; expanding the first expandable anchor in the coronary sinus; anchoring the first anchor in an anchored configuration in the coronary sinus, wherein in the anchored configuration the first anchor comprises 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 meeting the second segment at an apex of the first anchor between the distal and proximal ends of the first anchor; and anchoring the second anchor in the coronary sinus.
