Abstract: Disclosed herein are medical devices for diagnosing and treating anomalous tissue and methods of use. One embodiment of the medical device can comprise an energy source configured to emit at least an excitation beam and a therapeutic beam, a probe coupled to the energy source and configured to propagate the excitation and therapeutic beams with the beams capable of contact with the tissue, a sensor coupled to the probe that detects at least one predefined attribute of radiation emanating from the tissue when the tissue is subjected to the excitation beam and a controller coupled to the energy source and the sensor and programmed to selectively alternatively actuate the energy source to emit the excitation beam and the therapeutic beam in response to the detection of the at least one predefined attribute by the sensor.

Abstract: A spacer block that provides for a method of rebuilding an electrically operated automatic transmission controller assembly is disclosed. The block allows for offsetting and stabilizing or securing a printed circuit (PC) board to a manifold block, in which several solenoid assemblies reside within the span of the spacer block. The spacer block includes a first means for connecting to the manifold block and a second means for connecting to the PC board. The rebuilt solenoid module preferably includes at least one new solenoid.

Abstract: An apparatus for determining intraocular pressure includes a transducer assembly containing an applanation tonometer for the determination of a cornea applanation pressure and an ultrasonic pachymeter to determine the thickness of the cornea at the site of applanation. The assembly has a tip end which includes an applanation surface and an ultrasonic coupler surface, and an end cap membrane holder is adapted to fit over the tip end of the transducer assembly and hold a thin film membrane stretched over the applanation and ultrasonic coupler surfaces. The transducer assembly also has a detector for detecting the presence or absence of the end cap membrane holder, the detector may generate a signal to disable movement of the transducer assembly if the end cap is not detected.

Abstract: An improved apparatus and method of intraocular pressure determination is disclosed in which applanation tonometery is done simultaneously with pachymetry. The method allows for increased accuracy of intraocular pressure determination based upon adjustments of applanation tonometry for corneal thickness. The device allows an untrained operator to quickly and easily determine the accurate intraocular pressure.

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: An interactive computer system responsive to a user's voluntary and autonomic nervous system responses. The interactive computer system includes a computer, a voluntary input device requiring intentional actuation by the use, a sensor to detect autonomic nervous system responses, an interface device, and an output device. The voluntary input devices and output devices communicate with the computer. The sensors detect autonomic nervous system signals of a user and generate signals representative of the responses. The interface device communicates with the sensors and the computer. The interface device conditions the signals generated by the sensors and transmits the signals to the computer. The computer is responsive to the signals and produces an output command which is in part dependent upon the signals. The output device responds appropriately to the output command produced by the computer.

Abstract: An apparatus and method for optically treating tissue by contact between the apparatus and the tissue. The apparatus includes a holder having a distal end having an opening in it, and a contact member for contacting tissue to be treated and for coupling optical energy from a source of optical energy into said tissue. The contact member is a curved lens mounted in and partially extending from the opening and freely rotatable about at least one axis relative to the holder. The holder has a single coolant flow channel proximal to the opening and the contact member for supplying a cooling fluid to the contact member. A gap is provided between the contact member and the opening for allowing the fluid to flow around substantially the entire outer surface of the contact member and out of the opening onto said tissue to cool the tissue.

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.

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.

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.
