  • Patent number: 8282591
    Abstract: An apparatus for positioning a graft and catheter operable for subcutaneous access to the vascular system of a patient. A surgically created, hybrid arteriovenous shunt is provided which comprises a flexible graft and a venous outflow catheter connected to the graft via surgical anastomosis over a cuff. The graft is connected to an arterial source and then to a single lumen venous outflow catheter which deposits dialyzed blood directly into the heart at the right atrium. Methods of surgical placement and performing hemodialysis using embodiments of the apparatus are provided.
    Type: Grant

  • Publication number: 20050020975
    Abstract: This abstract describes our product which is in the class of suction catheter systems. Our product is specifically designed for treating acute airway obstruction. Our system comprises a reservoir which is attached on one end to the wall suction vacuum using standard sump tubing. The other end is attached, via an adapter, to 15French suction tubing. This tubing is hooked to the suction catheters which the healthcare provider passes through an endotracheal tube into the trachea. A proximal balloon port is inflated with a 10 cc air filled syringe which inflates a distal cuff on the catheter. The distal cuff, which is 5 mm from the end of the catheter, creates a distal seal in the trachea which allows for the targeted suction force to remove the obstruction.

  • Patent number: 5210513
    Abstract: An electromagnetic apparatus such as a transformer or a single winding inductor is provided with a cooling arrangement. The apparatus has a magnetic core and a coil winding disposed about and carried by a leg of the core. The magnetic core has legs connected to the leg that carries the coil winding and these legs have flat surfaces that directly contact a flat surface of a metallic heat sink to thereby provide a direct heat conductive path from the legs to the heat sink. Heat generated in the coil winding is transferred to the heat sink via the leg that carries the coil winding and then to the heat sink via the legs that directly engage the heat sink. Heat generated in the magnetic core due to hysteresis or eddy current loss is also transferred to the heat sink.
