  • Patent number: 4936842
    Abstract: A disposable bipolar electrosurgical probe which can be readily applied to the tissue to be treated, then discarded. The probe comprises an elongated substrate member having a peripheral surface of dielectric material and a longitudinal axis extending between a working end and an attachment end. At least a pair of electrically isolated electrodes extend continuously on the peripheral surface of the substrate member between an active region at the working end and an electrical terminal region at the attachment end for quick connection and/or disconnection, respectively, to opposite poles of an RF generator. A handle with a quick disconnect mechanism is provided to physically support the probe and enable it to be selectively energized. The probes can be of a fail safe construction so as to assure that only a proper probe can be used for a desired treatment.

  • Patent number: 4659195
    Abstract: An inspection system in which a fiber optic borescope has an elongated flexible body extending between a control head at a proximal end and an objective assembly at a distal end. The distal end is slidably inserted through a tubular elongated flexible guide member which has an operating head at a near end and a distal collar at a remote end capable of deflecting in four discrete directions. The objective assembly of the borescope is capable of deflecting in two discrete directions. A telescoping rigid support member connects the control head to the operating head and slidably receives the flexible body of the borescope. When the support member is retracted, the control head is proximate to the operating head and the objective assembly extends far beyond the distal collar. When the support member is extended, the control head is distant from the operating head and the objective assembly lies proximate to the distal collar.
