  • Patent number: 10716589
    Abstract: A surgical instrument for cutting and grasping tissue comprising a handle assembly, an elongated member and first and second jaws. A first movable member moves the second jaw in a first direction about a first pivot axis in a grasping action and a second movable member moves the second jaw in a second direction different than the first direction and about a second pivot axis in a cutting action. A switch is positioned at the proximal portion of the instrument and a selecting member is actuated by movement of the switch, the selecting member movable between a first position to enable movement of the second jaw in the first direction and prohibit movement in the second direction and a second position to enable movement of the second jaw in the second direction and prohibit movement in the first direction.

  • Publication number: 20110029050
    Abstract: A method for cooling of a brain with localized hypothermia allowing for maintenance of the core body temperature is achieved by positioning a cooling catheter within a ventricular cavity of the brain. The cooling catheter includes an inlet channel and an outlet channel providing for a closed flow of a cooling fluid into and out of the cooling catheter. A sack is formed at a distal end of the cooling catheter. The sack is in fluid communication with distal ends of the inlet channel and the outlet channel such that the sack is continually flushed with the cooling fluid as the cooling fluid flows into and out of the cooling catheter. The sack, when filled, takes the shape and size of the ventricular cavity filling the ventricular cavity in which it is positioned. The method further includes cooling the cooling catheter and the ventricular cavity through the closed flow of the cooling fluid through the cooling catheter.

  • Publication number: 20110021877
    Abstract: A surgical portal and introducer assembly includes an introducer dimensioned for at least partial positioning within a tissue tract, and having a longitudinal introducer channel extending therethrough and a portal positionable within the longitudinal channel of the introducer. The introducer defines leading and trailing ends, and further has a frangible segment adapted to separate to expose the introducer channel. The portal has at least one longitudinal port for passage of a surgical object. The portal comprises a compressible material and is adapted to transition from a first expanded condition to a second compressed condition upon advancement through the longitudinal channel of the introducer to facilitate passage through the introducer whereby, upon separating of the frangible segment, the portal is released from the longitudinal channel to transition toward the first expanded condition to be generally secured within the tissue tract.

  • Patent number: 7734325
    Abstract: An imaging system for imaging an object. The imaging system includes a support member adapted to receive the object in an immobilized state. The system also includes first means for imaging the immobilized object in a first imaging mode to capture a first image, and second means for imaging the immobilized object in a second imaging mode, different from the first imaging mode, to capture a second image. The first imaging mode is selected from the group: x-ray mode and radio isotopic mode. The second imaging mode is selected from the group: bright-field mode and dark-field mode. A removable phosphor screen is employed when the first image is captured and not employed when the second image is captured. The phosphor screen is adapted to transduce ionizing radiation to visible light. The phosphor screen is adapted to be removable without moving the immobilized object. The system can further include means for generating a third image comprised of the first and second image.

  • Patent number: 4619271
    Abstract: An electronic thermometer includes a color coded probe permanently fastened by an electrical cable to a color coded isolation chamber to prevent inadvertent use of a rectal probe with an oral isolation chamber. Red and blue isolation chambers used for oral and rectal temperatures, respectively, can readily be used with one thermometer housing. A connector between the isolation chamber and the housing automatically connects and disconnects the probe and the thermometer circuits when the isolation chamber is inserted into or removed from the housing. Moreover, insertion of the probe into the isolation chamber automatically actuates a switch in the electronic thermometer housing to deactivate the electric circuits. Withdrawal of the probe from the chamber automatically supplies power to the thermometer circuits to ready the thermometer for operation.

  • Patent number: 4437467
    Abstract: An apparatus for use in monitoring fetal heartbeat and the like. The apparatus includes a tubular member having a distal end adapted to be inserted through the vagina and cervix of a woman in labor. A coil is movably mounted in the tubular member and is adapted to be rotatably attached to the fetus. A linear to rotary converter is provided for applying a rotary force to turn the coil for attaching to the fetus in response to the linear force applied by a user to the additional elements and additional means serve to yieldably r esist the linear force applied by the user.
