Percutaneous Mitral Valve Annuloplasty Delivery System

Abstract

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.

         2 . The tissue shaping system of  claim 1  wherein the delivery mechanism comprises a pusher. 
     
     
         3 . The tissue shaping system of  claim 1  tissue shaping system further comprising a cartridge adapted to contain the tissue shaping device, the delivery mechanism being further adapted to deliver the tissue shaping device from the cartridge to the delivery catheter. 
     
     
         4 . The tissue shaping system of  claim 1  tissue shaping system further comprising a dye port adapted to admit an imaging contrast agent to the lumen. 
     
     
         5 . The tissue shaping system of  claim 4  wherein the delivery catheter and delivery mechanism are further adapted to permit delivery of imaging contrast agent from the dye port to the lumen during delivery and deployment of the tissue shaping device. 
     
     
         6 . The tissue shaping system of  claim 4  further comprising a connector extending from a proximal end of the delivery catheter, the connector comprising the dye port and a device port, the delivery mechanism being further adapted to deliver the tissue shaping device from outside the patient to the delivery catheter through the device port. 
     
     
         7 . The tissue shaping system of  claim 6  further comprising a cartridge adapted to contain the tissue shaping device and adapted to connect to the device port of the connector. 
     
     
         8 . The tissue shaping system of  claim 1  further comprising a handle associated with the delivery mechanism. 
     
     
         9 . The tissue shaping system of  claim 8  wherein the handle is adapted to support the actuator. 
     
     
         10 . The tissue shaping system of  claim 8  further comprising a cartridge adapted to contain the tissue shaping device. 
     
     
         11 . The tissue shaping system of  claim 10  wherein the cartridge is further adapted to engage the handle during delivery and/or deployment of the tissue shaping device. 
     
     
         12 . The tissue shaping system of  claim 1  wherein the actuator is further adapted to operate the delivery mechanism to move the tissue shaping device with respect to the delivery catheter. 
     
     
         13 . The tissue shaping system of  claim 12  wherein the actuator is further adapted to move the tissue shaping device with respect to the delivery catheter to expose the anchor. 
     
     
         14 . The tissue shaping system of  claim 12  wherein the actuator is further adapted to recapture the anchor into the delivery catheter. 
     
     
         15 . The tissue shaping system of  claim 12  wherein the actuator comprises a rotating nut. 
     
     
         16 . The tissue shaping system of  claim 1  wherein the actuator is adapted to move the delivery catheter distally to lock the anchor. 
     
     
         17 . The tissue shaping system of  claim 1  further comprising a locking sleeve, the actuator being further adapted to move the locking sleeve distally to lock the anchor. 
     
     
         18 . The tissue shaping system of  claim 1  further comprising an attachment mechanism adapted to attach the tissue shaping device to the delivery mechanism. 
     
     
         19 . The tissue shaping system of  claim 18  wherein the attachment mechanism comprises a tether attached to the tissue shaping device. 
     
     
         20 . The tissue shaping system of  claim 18  wherein the attachment mechanism is further adapted to release the tissue shaping device from the delivery mechanism.
