Abstract
An apparatus for the repair of a cardiovascular valve has leaflets comprising a grasper capable of grabbing and co-apting the leaflets of the valve. In a preferred embodiment, the grasper has jaws that grasp and immobilize the leaflets, and then a fastener is inserted to co-apt the leaflets. The apparatus is particularly useful for repairing mitral valves to cure mitral regurgitation.
Claims21
1-12. (canceled)
A medical device for fastening cardiac valve leaflets, comprising
- a percutaneous catheter having opposing distal and proximal ends, and
- a deployable clip having first and second jaw elements moveable between an open and closed configuration, wherein the deployable clip is detachably engaged to the distal end of the percutaneous catheter.
A medical device for fastening cardiac valve leaflets, comprising
- a percutaneous catheter having a distal and proximal ends,
- a deployable clip having a stationary first jaw element pivotably engaged to a moveable second jaw element, wherein the deployable clip is detachably engaged to the distal end of the percutaneous catheter.
A method of treating a subject having a cardiac valve condition, the method of treatment comprising:
- introducing a medical device including a deployable clip having movable first and second jaw elements into a subject;
- positioning the deployable clip in proximity to the cardiac valve leaflets, wherein the movable first and second jaw elements are disposed about the cardiac valve leaflets in a first open position,
- actuating the moveable first and second jaw elements to a closed position to physically fasten together the cardiac valve leaflets between the first and second jaw elements, and
- deploying the clip from the medical device.
