Percutaneous mitral valve annuloplasty device delivery method

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 to move the delivery catheter proximally to expose the anchor;
• and
• operating the actuator to move the delivery catheter distally to lock the anchor.

A method of delivering and deploying a tissue shaping device in a lumen within a patient, the tissue shaping device comprising an anchor, the method comprising:

• inserting a delivery catheter into the lumen;
• percutaneously delivering the device to a target site within the lumen through the delivery catheter;
• operating a first actuator to expose the anchor;
• and
• operating the first actuator to lock the anchor,
• wherein the anchor is a first anchor, the tissue shaping device further comprising a second anchor disposed proximally to the first anchor, the method further comprising operating the first actuator to expose the second anchor;
• and
• operating a second actuator to expand and lock the second anchor.

A method of delivering and deploying a tissue shaping device in a lumen within a patient, the tissue shaping device comprising an anchor, the method comprising:

• inserting a delivery catheter into the lumen;
• percutaneously delivering the device to a target site within the lumen through the delivery catheter;
• operating a first actuator to expose the anchor;
• operating the first actuator to lock the anchor;
• operating a second actuator to release the tissue shaping device from a delivery mechanism.

A method of delivering and deploying a tissue shaping device in a lumen within a patient, the tissue shaping device comprising an anchor, the method comprising:

• inserting a delivery catheter into the lumen;
• percutaneously delivering the device to a target site within the lumen through the delivery catheter;
• operating an actuator to expose the anchor;
• operating the actuator to lock the anchor;
• and
• releasing the tissue shaping device from a delivery mechanism by disconnecting a tether from the tissue shaping device.

A method of delivering and deploying a tissue shaping device in a lumen of a patient, the tissue shaping device comprising an anchor, the method comprising:

• 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, comprising moving a pusher distally to push the device through the delivery catheter, wherein the pusher is attached to a handle, the delivering step further comprising moving the handle toward the cartridge;
• engaging the cartridge with the handle;
• operating an actuator to move the delivery catheter with respect to the anchor to expose the anchor, wherein the actuating step comprises rotating the actuator after the engaging step;
• and
• expanding the anchor.

A method of delivering and deploying a tissue shaping device in a lumen of a patient, the tissue shaping device comprising a distal anchor and a proximal anchor, the method comprising:

• 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 a first actuator to move the delivery catheter with respect to the distal anchor to expose the distal anchor;
• expanding the distal anchor;
• operating the first actuator to move the delivery catheter proximally to expose the proximal anchor;
• expanding the proximal anchor;
• and
• locking the proximal anchor in the expanded configuration, wherein locking the proximal anchor comprises applying an external actuation force on the proximal anchor, and wherein
• the step of applying an external actuation force on the proximal anchor comprises operating a second actuator to move a proximal anchor locking device distally.

A method of delivering and deploying a tissue shaping device in a lumen within a patient, the tissue shaping device comprising an anchor, the method comprising:
