The intellectual property of Neocision Medical provides broad protection for the use of an electrically heated wire to thermally cut through tissue and capture an intended volume of tissue in an excisional procedure for the removal of targeted tissue anywhere within the human body.
Developed over seven years by its dedicated medical product development team combined with internal funding of over $500K, Neocision Medical was granted U.S. Patent No.11,737,808 in 2023. Neocision Medical’s first issued patent discloses the recovery of an intact volume of tissue that proceeds with a delivery cannula distal end that is positioned in confronting adjacency with the volume of tissue to be recovered. A tissue cutting and capture assembly, formed by a plurality of metal leaf members, is deployed from the distal end of the delivery cannula. The tips of these leaf members support a pursing cable assembly, which is resistively heated by the passage of electrical current through the cable, attaining a temperature level sufficient to thermally cut around and circumscribe the tissue volume. These pursing cables are tensioned to complete the envelopment of the tissue volume by drawing the leaf member tips together. An essential attribute of the disclosed apparatus is the confinement of the path of electrical conduction of constant current required to achieve tissue cutting to only those portions of the deploying and retracting resistively heated portion of the electrically conductive cutting and pursing cable that are in direct contact with tissue.
In addition to the first issued U.S. patent, there are three pending U.S. patent applications and an international patent application filed under the Patent Cooperation Treaty (PCT). The PCT patent application will allow Neothermia Medical to seek patent protection for their invention in many countries simultaneously.
