Adjustable height focal tissue deflector
First Claim
1. A tissue shaping device adapted to reshape target tissue, comprising:
- an expandable anchor and a connector element extending from the expandable anchor;
a delivery catheter in which the expandable anchor and the connector are delivered to a lumen within a patient, wherein the expandable anchor has a collapsed delivery configuration within the delivery catheter; and
a lock that is adapted to lock the expandable anchor in one of a plurality of locked configurations within a lumen, wherein the lock comprises a first lock element and a second lock element which are movable relative to one another to lock the first lock element and the second lock element in a locked configuration to thereby lock the expandable anchor in one of the plurality of locked configurations.

Abstract
A tissue shaping device adapted to reshape target tissue adjacent to a lumen. In some embodiments, the device includes an expandable and contractable anchor, with the anchor having an adjustable height anchoring portion adapted to engage a wall of the lumen in at least first and second anchor heights, the anchoring portion being further adapted to be changed from the first anchor height to the second anchor height by a substantially proximally or a substantially distally directed actuation force. The invention is also a tissue shaping system including a tissue shaping device and a tool for adjusting the height of an anchor of the device. The invention also includes methods of using such tissue shaping devices and systems.
