  • Patent number: 7149562
    Abstract: A needle with fiber optic capability for spectrophotometric analysis includes a needle assembly including a needle body having an open tip and side radiation ports. A fiber optic element is disposed in the needle assembly for carrying electromagnetic radiation to the open tip area for transmission to a target area. Fiber optic bundles in communication with the radiation ports are disposed in the needle body for transmitting backscattered radiation to a light detector or sensor for spectrophotometric analysis. The needle assembly may include barbs for anchoring the device in place.

  • Patent number: 6981969
    Abstract: An orthogonal arterial catheter preferably includes a hub and a cannula. The hub preferably protects the cannula from potential kinking and shearing forces because the cannula upon exiting a patient's body enters the hub. The hub preferably provides a passageway through which the hose travels to a connector piece. The connector piece preferably attaches the device to a fluid line such as an arterial line transducer. In addition, the hub preferably includes a port that provides a channel through which a guide wire or a needle may gain access to the cannula. The hub also may include appendages extending from it to suture to the patient.

  • Patent number: 6890322
    Abstract: A securing device for a catheter that preferably includes a guard that covers a patient's upper or lower teeth and a latch mounted on the guard for releasably immobilizing a catheter with respect to the guard. The guard preferably includes (or is attached to) a wedge, which contacts the patient's molars to prevent the guard from shifting in the patient's mouth and assists in keeping the patients teeth apart.

  • Publication number: 20040127776
    Abstract: This invention relates to diagnostic and monitoring devices. According to the invention, spectrophotometric devices preferably include a needle assembly having a hollow needle body with radiation ports. Preferably, disposed in the body are fiber optic bundles for carrying electromagnetic radiation, such as visible, infrared light, and/or ultraviolet light to a sample and for transmitting backscattered radiation to a light detector or sensor. The needle configuration preferably allows for insertion subcutaneously into muscle tissue and/or into other organs. It permits evaluation of difficult to access areas and facilitates securing the device in place. Barbs may be provided on the needle to anchor the device in place.
