  • Patent number: 6132390
    Abstract: A deflectable stylet is comprised of a hollow tube with a reduced diameter distal portion including a semi-cylindrical ground portion to provide localized flexure wherein tension is applied to an axial tension wire fixed to the distal end of the hollow tube. The hollow tube is coupled to a rotationally fixed tip coupled to a rotationally fixed handle body. The handle body and the tip are telescoped longitudinally with respect to each other along the longitudinal axis of the hollow tube by means of a rotatable nut that advances out of or backs the handle into the tip. The tension wire is coupled to the handle body so that when the nut is rotated in a first direction and the handle body backed out, tension is applied to the wire which is then withdrawn from the hollow tube fixed to the tip causing the stylet to curve at its distal end. Rotation of the nut in the opposite direction reduces the tension on the wire causing the stylet to straighten at its distal end.

  • Patent number: 5824031
    Abstract: A steerable or deflectable distal tip of a cardiac instrument is provided by creating a differential tension in a distal portion, causing the distal portion either to curve if originally straight, or to straighten if originally curved. The differential tension can be created by a pull or push wire disposed in a longitudinal lumen of the instrument, which wire is attached at its distal end to the instrument. In another embodiment, the differential tension is created by thermoelectrically heated by metallic strip which is disposed within a lumen within the instrument in the form of a stylet. In another embodiment, the stylet is deformed by virtue of differential tension being applied between a pair of strips comprising the stylet.

  • Patent number: 5235975
    Abstract: A therapeutic device for providing cold treatments to cardiac pacemaker implantation patients is comprised of a bilobed chest pad having an elastic chest strap connected thereto. The chest strap is fixed at one end to the lower lobe of the chest pad and is wrapped around the torso of the patient under tension and temporarily is coupled to the opposing portion of the lower lobe of the chest pad. The cold compress, which is placed behind the chest pad over the incision site, is thereby firmly kept in contact with the incision site. A shoulder strap is slidingly coupled at one end to the chest strap and is positioned on the back of the patient and wrapped under tension behind the back and over the shoulder of the patient, which shoulder is adjacent to the incision site. The end of the shoulder strap is then temporarily coupled to the upper lobe of the chest pad.

  • Patent number: 4978336
    Abstract: Syringe holder carriers first and second syringes which contain proteins which, when mixed, become a tissue adhesive. A manifold locks onto the two syringes, receives the two streams and delivers them to an output nose. A standard needle detachably locks onto the nose of the manifold. Alternatively to a needle, a spray nozzle can be locked thereon.
