Abstract

This invention relates to a deployment compensator for reducing the expelling force of a compressed transcatheter valve while it is being deployed in a patient in need thereof, and methods of use thereof.

Claims

1. A deployment compensator for deploying a transcatheter prosthetic cardiovascular valve in a patient, which comprises an extension spring connecting an end block to a spring head, the end block sized to remain outside of a valve deployment catheter sheath and having a sheath guide block connected thereto for inserting into an end portion of a valve deployment catheter sheath, said end block and sheath guide block having a push rod aperature for mounting a push rod, the spring head having a spring barrel connected thereto, the spring barrel disposed within the extension spring, and said spring head and spring barrel having a push rod aperture for mounting a push rod.

2. The deployment compensator of claim 1, further comprising in combination a push rod having a collet a a distal end and a removable epicardial attachment pad attached to a proximal end of the push rod.

3. The deployment compensator of claim 1, wherein the device has one or more radio-opaque markers thereon to facilitate positioning.

4. The deployment compensator of claim 1, where the device fits within a surgical catheter sheath having a diameter of between about 10 Fr (3.3 mm) to about 42 Fr (14 mm).

5. A method of reducing the expelling force of a compressed transcatheter prosthetic cardio-vascular valve out of a delivery catheter during deployment in a patient, which comprises the step of connecting a valve tether to a deployment compensator as in claim 1 while the valve is being expelled from the delivery catheter being used to surgically deploy the valve into the patient in need thereof.
