Abstract
The present invention provides a novel tissue cutting device which accurately cuts the tissue to a predetermined configuration in a minimal amount of time, and where the tissue may then be used in an autologous heart valve. The disposable tissue cutting die of the present invention is comprised of a cutting die assembly and a cutting base assembly. The cutting die assembly retains a continuous blade with razor sharpened edges that enclose a desired spatial configuration. The cutting base assembly includes a rotatable cutting pad on which the tissue to be cut may be placed. The cutting die assembly and cutting base assembly are adpated to cooperate to cut the tissue when the cutting die assembly is inserted into the cutting base assembly and rotated approximately 180 degrees.
