  • Patent number: 5830172
    Abstract: A device for the transfer of body fluids which accumulate in the peritoneum cavity into the vascular system comprising a peritoneal tube connected to the inlet chamber of a hollow plastic implanted valve assembly, causing a valve to open and passing the fluid under pressure into a second chamber from where the fluid is conducted through a venous tubing which is connected to the jugular vein of the patient. The valve assembly comprises a plastic housing with an inlet and outlet, the peritoneal tube being secured to the inlet leading to an inlet reservoir located within the valve housing and the venous tube being secured to the outlet leading from the outlet reservoir located within the valve housing.

  • Patent number: 5810755
    Abstract: A wound dressing, suitable for use in protecting an open wound or burned tissue from direct exposure to air and capable of maintaining an aqueous environment of wounded tissue with which it is in brought into contact is comprised of a hydrophilic, yet insoluble material, advantageously a polymeric compound capable of being reversibly complexed with elemental iodine, thereby permitting release of therapeutic amounts of free iodine into a wound with which it is brought in contact. As a shaped mass of pliable and absorbent material, such a polymeric foam, such dressing is particularly suited for application to fresh and infected burns and open wounds. When alternatively configured as a hydrophilic film complexed with free iodine for use as a surgical drape, in addition to providing a barrier against direct exposure to air, such dressing is bacteriocidal, preventing infection of the wound from airborne contaminants in the operating room.

  • Patent number: 5573547
    Abstract: A method of fixation for use within animal and human bodies provides for the insertion of brushes, of cylindrical and conical designs, into openings wherein bristles of the brushes are deflected by walls of the openings such that the brushes are locked in place and resist forces applied thereto. An embodiment of the invention includes boring a hole into a cancellous bone structure and inserting a brush into the hole. The hole is of a smaller diameter than the brush and is locked in the hole by the bristles. Tissue, such as tendon, may then be attached to material affixed to an end of the brush. Another embodiment of the method includes insertion of a brush into a blood vessel such that the blood flow is either occluded or strained by the bristles of the brush.

  • Patent number: 5388449
    Abstract: An osmolarity sensor continuously senses an osmolarity of a fluid. A principle of operation is based on achieving an equilibrium of a vapor pressure of a specimen solution with a vapor pressure of a standard solution. In an embodiment, the standard solution is contained in a cavity defined by a vapor-permeable membrane which is immersed in a specimen solution. The standard solution and the specimen solution are allowed to come into equilibrium by a movement of water vapor across the vapor-permeable membrane, which is permeable only to water vapor and not to any solutes or water itself. The movement of the water vapor between the standard solution and the specimen is measured by sensing a volume of water transferred between the standard solution and the specimen solution. A measurement of a volume change of the standard solution is made by sensing a change a conductivity of the standard solution.

  • Patent number: 5110801
    Abstract: Acne is treated by administering to the subject a substance which is effective in blocking glucose entry into sebaceous cells, thereby inhibiting the production of sebum by these cells. Typically, the substance is administered topically and is dissolved or suspended in an appropriate solvent. The preferred substance is phloretin, which can for example, be dissolved in propylene glycol.

  • Patent number: 5099756
    Abstract: Apparatus for treating neoplasms in humans and animals comprising a hollow toroidal applicator which resonates at a specific radiofrequency, and which possess electrically conductive walls on which radial radiofrequency currents flow and generate a high density of uninterrupted magnetic flux within the hollow body. A rotatable antenna connected to a source of radiofrequency power is mounted inside the applicator body to couple with the electromagnetic field of the applicator. The body part to be treated is interposed through side apertures or through the space created by removing a segment of the toroid which can have orifices of predetermined cross sectional areas across which a tubular zone of high magnetic flux travels through the interposed tumor and normal tissue to induce more heat in the interposed tumor tissue than in the interposed normal tissue.

  • Patent number: 5010897
    Abstract: An apparatus for the deep heating of cancers employing two single turn coaxial coils of varying diameter ranging from 2 inches to 6 inches which rotate synchronously in planes which are parallel to each other with the central axis of each coil lying in exactly the same line which is perpendicular to the plane of the coil. When the two coils are at 180.degree. from each other a line drawn through the central axes of both coils traverses the center of a tumor in the body which is to be heated and is not perpendicular to the two planes of rotation. The coils are placed so that the inner curvature of the rotating coil is tangential to the center of the tumor mass with the summated magnetic field of the rotating coils continuously heating the tumor with the maximum number of lines of magnetic force.

  • Patent number: 4840939
    Abstract: Malignant, neoplastic cells are treated by inhibiting glucose transport into the cell by administering phlorizin, phloretin or its analogs while concurrently administering adjunct therapy such as heat, radiation or chemotherapy. In this manner, the cells are prevented from growing or repairing the damage caused by the adjunct therapy, which can be administered in dosages that would otherwise be non-lethal if used alone.

  • Patent number: 4837017
    Abstract: The present invention relates to a non-enzymatic and non-toxic urease antigen and a method for its production. Administration of the urease antigen in living organisms serves to immunize the same from certain types of ammonia production without causing ammonia toxicity when injected, thereby promoting several advantageous biological activities including the promotion of wound healing, and general immunity from ammonia toxicity and the related effects thereof, and the cessation of toxic ammonia production in infections caused by urea splitting organisms.

  • Patent number: 4813855
    Abstract: A peristaltic pump for pumping fluids through a flexible tube is described which has a quick release and engagement mechanism that permits easy and rapid removal or insertion of the flexible tube into the device. The quick release and engagement mechanism of the invention consists of a shoe mounted for vertical displacement on the body of the pump. Upward movement of the shoe engages the flexible tube holding the fluid to be pumped and locks the tube against the roller assembly containing an eccentrically mounted roller which intermittently engages the tube and forces fluid out of it. To disengage the flexible tube from the pump, the shoe is moved downward out of contact with the flexible tube.
