ABSTRACT:
An apparatus and method for electrically induced thrombosis. The surgical device includes a first electrode and a second electrode. The first electrode is for placement adjacent to, near, or within a treatment site of a patient. The second electrode can be movable with respect to the first electrode. When the electrodes are charged by an electricity source, negatively charged blood components are attracted to the positively charged electrode while being repelled from the negatively charged electrode. Due to the electric potential between the adjacent electrodes, thrombosis is induced. The negatively charged blood and components form a thrombus or a clot adjacent to the positively charged electrode. The surgical device can be used to induce the otherwise natural process of thrombosis. When the surgical device is used in a treatment site such as a puncture or incision, the thrombosis can seal the opening created by the treatment site.
