Abstract: A system and method is provided to accurately treat sites on an eye's retina employing computer based image generation, processing and central control means in conjunction with diode laser sources and optical fibers. The system and method accurately determine geometry of a treatment zone of a specific eye's fundus and adjust a treatment beam to irradiate the treatment zone with minimal coverage of adjacent well tissue. The treatment zone or zone is accurately determined with digital processing of angiographic data and slit lamp image data. This information is integrated with information on the treatment beam characteristics to better match treatment beam coverage with minimal overlap with healthy areas of the fundus. Additionally preferred embodiments also have the ability to automatically track eye movement and switch the beam source depending on eye movement, adjusting the beam spot area in real time.

Abstract: An elbow terminator has a socket in which an electrical probe is disposed. The terminator is insertable onto an electrical bushing such that a tongue of the bushing is received in the socket of the terminator, and the probe of the terminator is electrically coupled to a contact sleeve disposed within the tongue. A latching mechanism produces positive latching between the tongue and socket when the tongue has been inserted to a predescribed depth within the socket. In order to enable an operator to visually observe that the tongue has been inserted to the prescribed depth, the bushing carries a color band which becomes completely disposed (invisible) in the socket when positive latching occurs. Alternatively, the bushing can be provided with gauge tabs which become aligned with a witness line formed on the terminator when positive latching occurs.

Abstract: Laser systems medical or cosmetic applications, comprising diode lasers or diode lasers with other solid state lasers which can deliver up to 30 cw or more, and which generally operate at more than wavelength within the range of 1000 to 1300 nm are presented. Individual emitter or emitter groups within the diode laser system can be powered independently. These laser systems provide maximum penetration depths for procedures such as Laser-induced Interstitial Tumor Therapy, alone or in conjunction with other therapies such as PhotoDynamic Therapy, chemotherapy, or radiation therapy. Where beneficial for the procedure, the operating wavelength of the system can be changed without interruption. In some variants, active tissue cooling at the distal end of the delivery fibers is incorporated as well as individual feedback loops to control and stabilize the temperature induced in the tissue.
