  • Patent number: 5484434
    Abstract: A surgical scalpel for cutting the tissue of a patient and for selectively applying an electrosurgical cutting current or an electrosurgical coagulation current from an electrosurgical generator to the patient, includes a scalpel body defining a contoured external surface configured to be held comfortably in the hand of a surgeon, and an electrically conductive blade, mounted on and extending from the scalpel body, for cutting the tissue of a patient and for selectively applying electrosurgical cutting current or electrosurgical coagulation current to the tissue of a patient. The scalpel further includes a cable having an electrical connector for electrical connection to the electrosurgical generator, and manual switch means, mounted on the scalpel body, for controlling the application of electrosurgical cutting current and electrosurgical coagulation current to the tissue of a patient.

  • Patent number: 5443440
    Abstract: A medical device is provided for applying compressive pressures against a patient's foot. The device comprises first and second panels of flexible material secured to one another to form an inflatable bag to be fitted upon the foot. The bag has first and second separate fluid bladders. The first fluid bladder is adapted to engage a first portion of the foot and the second fluid bladder is adapted to engage a second portion of the foot. A boot is provided for holding the inflatable bag to the foot. A fluid supply is provided for applying pressurized fluid to the first and second fluid bladders such that the first fluid bladder applies a first compressive pressure upon the first portion of the foot and the second fluid bladder applies a second compressive pressure upon the second portion of the foot.

  • Patent number: 5005592
    Abstract: A device for tracking catheters includes an oscillator which is coupled to a transmit coil. The transmit coil is rotated in a direction transverse to the longitudinal axis of the transmit coil. A receive coil situated on the guide wire of a catheter inserted into a patient's body receives the signal transmitted from the transmit coil. A rectifier rectifies the received signal, and a filter filters the rectified received signal. A strobe circuit provides strobes of light in response to the rectifie received signal and cooperates with bar image forming circuitry and structure to provide an image of a bar which is aligned with the longitudinal axis of the receive coil, which is indicative of the orientation of the catheter and guide wire on which the receive coil is situated. A bar display indicates the relative proximity of the transmit coil to the receive coil, and a numeric display provides a read-out of the distance between the transmit coil and the receive coil.

  • Patent number: 4800878
    Abstract: A disposable electrosurgical knife handle and blade is provided with a built-in warning light positioned on the top of the handle in the surgeon's line of vision during surgical procedures in order to warn, instantly, of unwanted surges in the electrical system which could bring about tissue damage. Because of the arrangement, the surgeon may remove immediately the blade or other cutting instrument fitted into the handle from the surgical site.

  • Patent number: 4485966
    Abstract: A heating system, such as a gas fired or oil fired furnace, is operated by a control system which includes a low voltage AC power supply, a low voltage thermostat for sensing the temperature in the space to be heated and a solenoid controlled relay or fuel supply valve. The control system also includes a low voltage pulsation device which is connected in series with the thermostat and solenoid and is effective, when the thermostat closes, to pulsate or cycle the solenoid causing the heating unit to be turned on and off for supplying heat in increments to the heat exchanger within the furnace. The pulsation device is adapted to be quickly and easily installed in the low voltage control circuit for the heating unit or for a cooling unit.
