    Abstract: A heated fluid surgical instrument including a palm-sized handpiece having a cannula adapted to be inserted into a patient's body by way of a natural access (e.g., mouth) or a small incision. A channel is provided within the handpiece and the cannula for permitting the passage of a surgical accessory implement to the surgical site. Additional, channels are provided for passing fluid pumped into the handpiece from a remote fluid source to the surgical site. An irrigation control valve assembly on the handpiece permits a surgeon to selectively direct the flow of fluid through the handpiece and into one of two fluid flow paths. One of the paths heats the fluid and passes it to the surgical site to effect a therapeutic result. The other path sends the fluid directly to the surgical site.

    Abstract: A laser medical device for delivering energy to tissue to be treated. The device includes a laser energy transmitting conduit having a longitudinal axis, and has a proximal end for connection to a source of laser energy and a distal end from which laser energy transmitted by the conduit is emitted. A laser energy redirecting member is located adjacent the distal end of the conduit for redirecting the laser energy in a lateral direction with respect to the axis of the conduit, and a tissue contact member is provided adjacent the laser energy redirecting member. The tissue contact member has a transverse cross section of preselected shape and a longitudinal axis generally transverse to the axis of the conduit. The tissue contact member further has an input surface for receiving laser energy redirected by the laser energy redirecting member and transmitting the laser energy received from the laser energy redirecting member. The tissue contact member terminates in a tissue contact surface having a radius of curvature. The dimensions of the tissue contact member and the radius of curvature of the tissue contact surface are determined and structural such that laser energy is transmitted divergently therethrough and impinges upon the tissue contact surface in a substantially diffuse pattern.

    Abstract: A medical device has a flexible light guide having a light energy input end adapted for connection to a source of light energy and a light energy output end. The output end outputs a beam of light energy. The device includes a tip for contacting tissue to be treated by the device and irradiating the tissue with light energy. The tip consists essentially of light-transmissive material and has a working region for contacting and irradiating the tissue to be treated. The working region of the tip includes sidewalls. The tip has a bore therein for receiving the output end of the light guide. The output end of the light guide is at least partially surrounded by the light-transmissive material, and is positioned relative to the light-transmissive material so as to define an interface therebetween. The interface is in proximity to and in thermally-conductive relationship with the working region of the tip so that heat energy generated at the interface significantly raises the temperature of the tip's working region. The interface is sufficiently distant from the working region of the tip so as to allow at least a portion of the beam of light energy to strike the sidewalls at first locations, reflect back into the tip and exit the tip at second locations different from the first locations.

    Abstract: An apparatus for determining the usage of an optical conductor. The apparatus comprises a non-volatile memory operatively associated with the conductor for storing a cumulative usage value representative of the cumulative usage of the conductor. A device responsive to a parameter of use generates a signal representative of usage of the conductor. A circuit is provided which is responsive to the signal and is operatively associated with the memory for generating from the signal a usage value and then generating from the usage value and cumulative usage value stored in the memory an updated cumulative usage value representative of the total cumulative usage of the conductor, and for replacing the cumulative usage value in the memory with the updated cumulative usage value. The circuit may in addition compare the cumulative usage value to a predetermined value representative of maximum usage. Structure operatively associated with the circuit is provided for preventing further use of the conductor when the updated cumulative usage value reaches the predetermined value.

    Abstract: One or more sensors located on or surrounding a dangerous condition anticipate when an individual is approaching a hazard zone associated with the dangerous condition and then arms an alarm and activates an interactive protective system which protects an individual from exposure to the dangerous condition. The interactive system comprises a protective garment adapted to be worn by the individual. The protective garment includes a sensor for sensing when the protective garment is being worn and a signalling device responsive to the sensor for generating a signal indicating when the protective garment is being worn. A detector and control device responsive to the signal from the signalling device triggers an alarm sensible to the individual when it is activated by the motion sensor and does not sense the signal from the signalling device.

    Abstract: An apparatus for detecting a break in an optical fiber adapted for carrying optical energy such laser energy. The optical fiber has a core, a cladding concentric with and surrounding the core and a sheath concentric with and surrounding the cladding. A detector is located within the sheath and has a portion thereof contiguous with the cladding. The detector is adapted to detect both a break in the portion contiguous to cladding as a result of a break in the fiber and a change in transmission of optical energy resulting from a break in the fiber without a concomitant break in the contiguous portion, and to provide a signal indicative of a break in the fiber.

    Abstract: A low loss cladded halide fiber for transmission of infrared energy is provided, and a process for making the same by growing a single crystal ingot from a powder of a core halide, extruding or machining the ingot to provide a cylindrical billet core, assembling the billet core, preferably wrapped in a polymer film, within a sleeve member of a second halide of lower refractive index than the core, prepared in the same fashion as the core, and coaxially core drilled to accept the billet core. The assembled composite billet is covered with a polymer film, heated, and extruded to form a polymer coated fiber having a diameter in the range of 75 to 2,000 microns. The extruded fiber may be rapidly cooled as it leaves the extrusion die to minimize grain size and scattering loss and may be contained in a coaxial outer strength member.
