Latest Patents

Keith A. Earles holds a patent for an in vitro tissue testing system. This system is especially useful for testing blood and tissue interactions. It includes a tissue holding frame that forms a chamber between two flat pieces of tissue with a spacer plate in between. The spacer plate features a reservoir aperture bordered on both sides by the opposed tissue pieces. A mechanism is included to depress portions of the tissue pieces inwardly into the chamber, propelling blood from one side to the other. This flow simulates actual blood flow in a host system. The reservoir aperture may be hourglass-shaped with circular end portions and a middle blood passageway. The actuating mechanism may consist of pistons that alternate contact with the tissue within the confines of the opposite reservoir end portions, thus propelling blood from one end portion to the other. The pistons are driven by a plurality of eccentric cams on shafts coupled to a common drive motor. The holding frame includes two outer plates that sandwich the tissue pieces against the spacer plate, with openings corresponding to the reservoir end portions, allowing the pistons to reciprocate through the openings into contact with the tissue.
