  • Patent number: 7334307
    Abstract: A disposable set screw system which comprises inserting the set screw to the desired depth, removing the excess shank portion, and multiple methods for removal of the set screw when desired that in turn improves efficiencies over fixture setup of prior art.
    Type: Grant
    Filed: May 23, 2006
    Date of Patent: February 26, 2008
    Inventor: Tomasz K Helenowski
  • Patent number: 7302037
    Abstract: A method and system of visual inspection for use with a gamma system includes a monitoring device connected within a housing proximate to a mechanical indicator of the rotating gamma system for capturing data comprising at least one of positional and operational data associated with the mechanical indicator. A control center monitors the captured data which is provided by a communication device connected between the monitoring device and the control center. Upon display of the captured data a user is able to review, monitor and maintain operation of the gamma system.

  • Patent number: 5531673
    Abstract: A tubular ventricular catheter having an improved distal open end that improves the fluid flow therein and which reduces the tearing of any choroid plexus or other brain tissue which might grow into the lumen of the catheter. The catheter tip is provided with longitudinal slots extending from the distal end and partially through the elongated body of the catheter. To preserve the open communication of the tip to fluid flow the edges of the longitudinal slots can be scalloped by a series of semicircular cutouts, which will form lateral passageways into the center bore of the catheter in the event the distal open end collapses. The catheter is also equipped with an electrical signal generator which will function to prevent growth of tissue into the lumen, and aid in proper placement of the proximal end of the catheter in the ventricle.

  • Patent number: 5084045
    Abstract: A surgical instrument consisting of three concentric tubes, with the outer and inner tubes made of electrical current conducting material which are in turn connected to a bipolar current generator. When the tips of such tubes are placed against tissue a current will flow therebetween and cauterize such tissue. To prevent short circuiting between the two conductive tips the third or middle tube constitutes an insulator. A suction tube equipped with a suction regulator is integral with the instrument and has open communication with the current conductive tips which are designed to be longitudinally separated by an open slot that allows continuous air flow therebetween and into the suction tube during the surgical procedure.

  • Patent number: 4548516
    Abstract: An apparatus for indicating the fluid flow through implanted shunts by temperature sensing. The sensor comprises a series of thermistors carried by a flexible substrate mounted on a rigid support. The sensors are placed in external proximity to a section of the implanted shunt and by varying the temperature of the fluid proceeding the test section, the apparatus will determine the rate of flow therethrough. Each thermistor is connected by conductors to scaling and amplification circuitry for input into a computer system.
