  • Patent number: 6379308
    Abstract: A device measures pressures in animals and humans and includes a pressure transmission catheter (PTC) filled with a pressure transmitting medium and implantable in an area in having a physiological pressure. A transducer communicates with the pressure transmitting medium to provide a pressure signal representing variations in the physiologic pressure on electrical wires. A connecting catheter carries the electrical wires to signal processing and telemetry circuitry, which transmits a telemetry signal representing the pressure signal to a receiver external to the animal or human. A housing holds the signal processing and telemetry circuitry, but the transducer is remote from the housing. The device is particularly useful in measuring venous pressure, pulmonary pressure, bladder pressure, or intracranial pressure without significant head pressure artifact and with a sufficient dynamic response. One embodiment of the PTC includes a multi-durometer stem.

  • Patent number: 6371937
    Abstract: A manometer for measuring the hydrodynamic pressure of fluids parenterally administered to a patient is disclosed. The manometer includes a transparent housing that has a passage that accommodates continuous flow of fluid. A pressure-measuring chamber is formed in the housing with one end in fluid communication with the passage. The other end of the chamber communicates with an enclosed air space. The fluid flowing through the passage enters the pressure-measuring chamber and rises to a level which is dependent upon the pressure of the fluid flowing through the passage. A space-saving chamber is provided, which is in air communication with the pressure-measuring chamber, and which allows the housing to be reduced in size. Markings are provided on the housing which indicate the relative flow state of fluid flowing through the passage.

  • Patent number: 6353754
    Abstract: An epileptiform activity patient template creation system is provided which permits the user to efficiently develop an optimized set of patient specific parameters for epileptiform activity detection algorithms. The epileptiform activity patient template creation system is primarily directed to a computer software package which operates within a computer workstation having a processor, disk storage and display for storing, processing and displaying patient EEG signals. The computer processor in conjunction with the software package allows for the marking of the initiation/termination of electrographic seizures within the patient's displayed EEG signals. Epileptiform activity segments are extracted from at least one of the EEG signals with the activity segments including a marked initiation of a seizure. Subsequently, a seizure data set simultaneously displaying a number of the epileptiform activity segments is shown on the display monitor.

  • Patent number: 6352550
    Abstract: Flexible multijoint thermal therapy pads which are dimensioned and structured to promote effective thermal therapy by promoting increased flexibility, comfort, convenience and heat transfer when applied to a range of joints in the body. Pads according to the present invention feature distinct members each of which corresponds to and may be applied to conform to a limb or body part surrounding the knee, shoulder and other joints. The pads connect these members using at least one conduit that is not substantially centered on the kneecap or top of the shoulder when they are applied for thermal therapy on the knee or shoulder, respectively. The pads thus do not blindly adhere to traditional multijoint notions of symmetry, but instead opt for increased flexibility, prevention of undesired blockage or occlusion during joint flexure and restriction of range of motion.

  • Patent number: 6343225
    Abstract: The sensitivity of enzyme-based polarographic electrodes to oxygen concentration can be significantly reduced or eliminated by providing an oxygen-reservoir in intimate contact with the oxidative enzyme. This is achieved by making a stabilized emulsion between the enzyme and a compound in which oxygen is extremely soluble. An aqueous glucose oxidase solution is emulsified with a perfluorocarbon liquid, and the resulting emulsion is stabilized by chemically crosslinking the mixture to form a gel. Thin layers of the emulsion are fabricated by spreading a layer of the liquid emulsion before gelation occurs. Additional carrier proteins such as albumin may be added to the enzyne prior to crosslinking to protect enzymatic activity and enhance gel strength. Additional electron transport compounds may be added to further reduce sensitivity to oxygen concentration.

  • Patent number: 6334074
    Abstract: A hand held applicator for delivery of microwave energy to skin surfaces is provided that is compact, easily manipulated, precisely positionable and secure against malfunction. Microwave energy of a chosen frequency is supplied for a given duration at a predetermined energy level, via one or more waveguides having a distal end section that is dielectrically loaded and matched to skin impedance. Positioning indicia may be disposed on a single use end cap adjacent the emitter end of the applicator to permit easy visualization by the surgeon or technician. Coolant, such as a pressurized gas refrigerant, is supplied in a burst to the skin surface via an interior solenoid controlled valve. The microwave energy pulse is initiated by control circuits after the effective delivery of coolant is sensed. The initiation of the cycle can be effected by actuation of a switch, movement of the applicator against the skin, or by tracking the movement of the applicator from one position to another.
