  • Patent number: 6539252
    Abstract: A method and apparatus for destroying blood borne pathogens is disclosed which utilizes a low intensity direct current to generate positive particles from various metals which destroy viral pathogens. A first electrode comprised of a metal such as silver is inserted into a patient's venous system. Then, a second electrode is placed on the patient's exterior in the vicinity of the first electrode. A low intensity direct current is applied to the first metal electrode which releases silver cations to be bonded to the virus, resulting in the denaturing of the virus. The first electrode is placed in the venous system of the infected patient via a catheter.

  • Patent number: 5823961
    Abstract: A flushing device comprises a catheter guidewire flushing apparatus comprising a connector having an insertion port, an outlet port and a flushing port and a catheter having rails extending the length thereof. The invention allows a clinician to adjust the length of a catheter, to insert the catheter while flushing to maneuver the catheter through a tortuous blood vessel, and to easily remove the guidewire for safe disposal. The catheter can then be left in place in the blood vessel.

  • Patent number: 5776096
    Abstract: A dual lumen vascular catheter with expanding side portal includes a cylindrical tubing with one or more lumens inside. An effusion portal is located on the side of the tubing at an end of one lumen. The portal is oval-shaped, with an open-ended slit connected to an end of the oval opening. The slit is thereby expandable, allowing for vacuum relief during aspiration of blood in the event that the catheter is lodged with the portal pressed against an inner wall of the vein.
