Abstract
The present invention provides a tissue cutting device and a method for accurately cutting tissue into tissue leaflets for autologous tissue heart valves in a minimal amount of time. The device includes a flexible backing pad located between a rotatable rotary table and a puck which houses several sharpened blades. The tissue to be cut is located on the flexible backing pad adjacent to the blades. The rotary table includes a hemispherically shaped raised cutting bar on the upper surface. When the rotary table is rotated, the cutting bar pushes the tissue against the blades in the puck, cutting the tissue into the desired shape.
