Abstract
A prosthetic device inserted into a blood vessel decreases the severity of valve regurgitation during ventricular contraction. The prosthetic device reduces the circumference of the valve annulus, causing the valve leaflets attached to the annulus to close more completely. A first preferred embodiment is an elongated member that includes distal and proximal segments separated by an intermediate segment. The prosthetic device has at least one anchor control wire to anchor the device in the blood vessel and at least one length control wire. A second preferred embodiment is an elongated member that includes distal and proximal segments that are connected by a pivot or hinge joint. A control wire is anchored on the distal segment and pivotally moves the distal and proximal segments closer together. Rotation of the length control wire of the first embodiment or the control wire of the second embodiment reduces the circumference of the valve annulus.
