Abstract
The present invention provides a novel tissue cutting device for autologous tissue heart valves which accurately cuts the tissue to a predetermined configuration in a minimal amount of time. The disposable tissue cutting die of the present invention is comprised of a cover, a base member, a continuous blade enclosing a desired spatial configuration and an actuator for forcing said tissue against the entire perimeter of the blade.
Claims13
An apparatus for quickly and precisely cutting a piece of autologous, homologous, or heterologous tissue to a desired spatial configuration, said apparatus applying a consistent cutting force substantially independent of the force applied by the operator so that the tissue is substantially completely and automatically cut along the perimeter of said desired spatial configuration, said apparatus comprising:
- a cover;
- a blade defining the perimeter of the desired spatial configuration, said blade supported by said cover, and means for sequentially forcing segments of a larger piece of said tissue against said blade so that said blade precisely cuts a smaller portion of tissue out of said larger tissue piece by shearing said larger tissue piece substantially along the entire perimeter of said blade.
