Adjustable height focal tissue deflector
First Claim
1. A tissue shaping device adapted to reshape target tissue adjacent to a lumen, the device comprising an expandable and contractable anchor, the anchor comprising 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.

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.
