Latest Patents

One of Tompkins' latest patents is a rotary tissue cutting die. This invention provides a tissue cutting device and a method for accurately cutting tissue into leaflets for autologous tissue heart valves in a minimal amount of time. The device features a flexible backing pad located between a rotatable rotary table and a puck that houses several sharpened blades. The tissue to be cut is positioned on the flexible backing pad adjacent to the blades. As the rotary table rotates, a hemispherically shaped raised cutting bar pushes the tissue against the blades, effectively cutting it into the desired shape.

Another notable patent is for a heart valve that incorporates tissue retention with anchors and an outer sheath. This apparatus and method allow for the construction of a heart valve made from autologous tissue. Three tissue leaflets are secured in place with tissue anchors on a mounting frame that has an annular base and multiple commissure posts extending from it. An elastomeric sheath gently rests on the tissue leaflets to prevent them from detaching from the anchor hooks, enclosing the leaflets to form valve cusps. The design ensures that the leaflets touch each other at a coaptation line with an angle of approximately 65 degrees relative to the commissure post. This innovative heart valve can be constructed intraoperatively in a short time, typically around ten minutes, while minimizing stress on the tissue.
