20100100175Adjustable Height Focal Tissue Deflector - 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.04-22-2010

20080319542Tissue Shaping Device - In one embodiment, the present invention relates to a tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart. Such tissue shaping device can include an expandable proximal anchor; a proximal anchor lock adapted to lock the proximal anchor in an expanded configuration; an expandable distal anchor; a distal anchor lock adapted to lock the distal anchor in an expanded configuration; and a connector disposed between the proximal anchor and the distal anchor, the connector having a substantially non-circular cross-section.12-25-2008
20110035000Tissue Shaping Device - In one embodiment, the present invention relates to a tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart. Such tissue shaping device can include an expandable proximal anchor; a proximal anchor lock adapted to lock the proximal anchor in an expanded configuration; an expandable distal anchor; a distal anchor lock adapted to lock the distal anchor in an expanded configuration; and a connector disposed between the proximal anchor and the distal anchor, the connector having a substantially non-circular cross-section.02-10-2011
20110066234Percutaneous Mitral Valve Annuloplasty Delivery System - The invention is a tissue shaping system, including a tissue shaping device with an expandable anchor and a lock; a delivery catheter; a delivery mechanism adapted to deliver the tissue shaping device from outside a patient to a target site within a lumen within the patient via the delivery catheter; and an actuator adapted to deliver an actuation force to the lock to lock the anchor in an expanded configuration. The invention is also a system adapted to percutaneously deliver and deploy a tissue shaping device at a target site within a lumen of a patient. The system includes: a handle; a delivery mechanism supported by the handle and adapted to deliver the tissue shaping device from outside the patient to the treatment site via a delivery catheter; and an actuator supported by the handle and adapted to deliver an actuation force to lock an anchor of the tissue shaping device in an expanded configuration.03-17-2011

20110004430EDDY CURRENT DETECTION AND COMPENSATION - A distortion compensation method includes determining an undisturbed phase for at least one of a first position indication signal and a second position indication signal. The method includes determining an undisturbed ratio that relates the amplitude of the first position indication signal at a first frequency to the amplitude of the second position indication signal at a second frequency. The method also includes determining a disturbed amplitude of the position indication signal and adjusting a position indication based on the disturbed amplitude and phase, the undisturbed amplitude ratio, and the undisturbed phase. The method further comprises determining a relationship between the eddy current phase of the first position indication signal and the second position indication signal.01-06-2011
