Percutaneous mitral valve annuloplasty device delivery method
First Claim
1. A method of delivering and deploying a tissue shaping device in a coronary sinus within a patient, the tissue shaping device comprising an anchor, the method comprising:
- inserting a delivery catheter into the coronary sinus;
percutaneously delivering the device to a target site within the coronary sinus through the delivery catheter;
operating an actuator in a first direction to allow the anchor to self-expand outside of the delivery catheter; and
operating the actuator in a second direction to lock the anchor,wherein operating the actuator to lock the anchor occurs after operating the actuator to allow the anchor to self-expand outside of the delivery catheter, andwherein the second direction is opposite the first direction.

Abstract
The invention is a method of delivering and deploying a tissue shaping device in a lumen within a patient, with the tissue shaping device including an anchor. In some embodiments the method includes the steps of: inserting a delivery catheter into the lumen; percutaneously delivering the device to a target site within the lumen through a delivery catheter; operating an actuator to expose an anchor; and operating the actuator to lock the anchor. In other, the method includes the steps of: inserting a delivery catheter into the lumen; moving the device from a cartridge into the delivery catheter; delivering the device to a target site within the lumen; operating an actuator to move the delivery catheter with respect to the anchor to expose the anchor; and expanding the anchor.
