  • Publication number: 20090191287
    Abstract: The present invention comprises formulae and methods that mitigate post-trauma inflammation, thus reducing overall damage to a patient. The formulae includes a uric acid agent, preferably a uric acid inhibitor, along with at least one other compound that is an inflammatory response suppressor. One preferred inflammatory response suppressor is a compound that reduces the omega 6/omega 3 EFA ratio in the body and preferably includes a source of omega 3 EFAs. The formulae are designed to minimize the formation of uric acid, which stimulates inflammatory response, and also minimize the production of ROS, an abundance of which is required for several inflammatory precursors or processes. A method of the present invention preferably includes prophylactic treatment of patients who are at risk for trauma, particularly traumatic brain injury, and includes daily administration of the selected formulation during the period of time in which risk is present.

  • Patent number: 6280415
    Abstract: A tissue traction device according to the invention includes an elongated tube defining a vacuum passageway, which tube has a proximate end defining a first opening, a distal end defining a second opening, and a third opening between the ends. A shield covers the distal end of the tube, the shield having a plurality of openings providing communication between the vacuum passageway and an exterior surface of the shield. The shield prevents the tissue from being pulled deep into the tube, thereby protecting the tissue from damage. Each of the openings having a cross-sectional area smaller than the cross-sectional area of the vacuum passageway. The tube and shield are configured for use in surgery, such that when suction is applied to one of the first and third openings, the level of suction through the second opening can be controlled by varying the extent to which the other of the first and third openings is uncovered, whereby the suction causes the shield to selectively hold tissue against the shield.

  • Patent number: 5915949
    Abstract: The invention provides a method for controlling pests which, according to one aspect of the invention, uses a laser beam to exterminate pests hidden behind or within a solid barrier. The laser light must have a wavelength and power to sufficient exterminate the pests hidden behind or within the barrier without damaging the barrier. Such a method can be used to control ant and termite infestation of common household building materials and agricultural pest control of crop fields.

  • Patent number: 5343652
    Abstract: The invention provides an apparatus and a method for controlling pests which, according to one aspect of the invention, uses a laser beam which is scanned over a defined area and incapacitates sensory organs of various pests when they enter the defined area. Such a pest control system uses a laser source in cooperation with a scanner which then repetitively scans the laser beam throughout the defined area. Any pest which wanders into this area, or is attracted into this area, is likely to sense the laser beam, typically through its eyes or light spot. The laser beam is of sufficient energy to destroy the sensory organ and incapacitate the pest.

  • Patent number: 5306234
    Abstract: A method for operating on a heart is described. The method is directed to closing the passage between an atrium and its associated atrial appendage or completely removing the appendage. The method is structured to permit manipulation of the appendage without severing the sternum or ribs of the patient being operated upon. Rather, openings are made between the ribs to provide access to the heart for observation with a thoroscope and manipulation with appropriate surgical instruments.
