Abstract

A device, system and method for treating cardiac valve regurgitation. The device includes a compression member disposed on a tube and a sleeve rotatably disposed about the tube and the compression member. The sleeve includes a side port, and is rotatable to align the compression member with the side port to transform the compression member from a delivery configuration to a compression configuration. One method includes positioning the compression member adjacent a cardiac valve and rotating the sleeve to align the compression member with the side port to release the compression member from the delivery configuration to the compression configuration to apply a compressive force to the cardiac valve.

Claims

1. A system for treating cardiac valve regurgitation, the system comprising:

a device for treating cardiac valve regurgitation comprising;

a tube including a lumen there through;

a compression member carried on the tube; and

a sleeve rotatably disposed about the tube and the compression member, the sleeve including a side port formed therein, wherein the side port is alignable with the compression member by relative rotation between the sleeve and the compression member;

a delivery catheter; and

a release mechanism to releasably attach the delivery catheter to a treatment device,

wherein the release mechanism comprises;

a threaded attachment portion at a proximal end of the tube for threaded attachment to a threaded receiver portion disposed at a distal end of the delivery catheter.

2. A system for treating cardiac valve regurgitation, the system comprising:

a device for treating cardiac valve regurgitation comprising;

a tube including a lumen there through;

a compression member carried on the tube; and

a sleeve rotatably disposed about the tube and the compression member, the sleeve including a side port formed therein, wherein the side port is alignable with the compression member by relative rotation between the sleeve and the compression member;

a delivery catheter; and

a release mechanism to releasably attach the delivery catheter to a treatment device,

wherein the delivery catheter comprises a driving catheter, the driving catheter including a keyway disposed at a distal end, the keyway being sized and shaped for receiving a proximal end of the compression member when the compression member is in a delivery configuration.

3. A method for treating cardiac valve regurgitation, the method comprising:

providing a treatment device comprising a compression member disposed exteriorly on a tube and a sleeve rotatably disposed about the tube and the compression member;

positioning the treatment device in a blood vessel adjacent a cardiac valve; and

effectuating relative rotation between the sleeve and the compression member to align the compression member with a side port in the sleeve, thus deploying the compression member through the side port and into contact with the blood vessel.

4. The method of claim 3 wherein deploying the compression member deforms the blood vessel and applies a compressive force to the cardiac valve.

5. The method of claim 3 wherein the blood vessel adjacent the cardiac valve is a coronary sinus.

6. The method of claim 3 wherein positioning the treatment device in a blood vessel is executed via a delivery catheter.

7. The method of claim 6 further comprising:

releasing the treatment device from the delivery catheter after the compression member has been deployed.

8. The method of claim 7 wherein releasing the treatment device from the delivery catheter comprises rotating the delivery catheter in relation to the treatment device to unscrew a threaded engagement there between.

9. The method of claim 3 wherein deploying the compression member through the side port transforms the compression member from a delivery configuration to a compression configuration.
