  • Publication number: 20070147730
    Abstract: An optical switch incorporated in a photomedical system, and a method of treating tissue using the optical switch for creating pulsed light. A light source generates an optical beam. An aperture element includes a light-transmitting portion and a light-blocking portion. An optical element such as a mirror, prism or lens directs the optical beam to the aperture element, wherein the optical element is movable for translating the optical beam across the light-transmitting and light-blocking portions of the aperture element, or changing its angle of incidence through the aperture to produce one or more pulses of light from the optical beam. A lens focuses the one or more pulses of the optical beam onto target tissue. A controller controls the movement of the optical element to produce the one or more pulses of light.

  • Publication number: 20070126985
    Abstract: A photomedical system and method for treating and/or diagnosing a patient's eye that includes a first light source for producing light, a scanning device for deflecting the light to produce a pattern of the light on the eye, a viewing element positioned to view the eye by a user or physician, and an alignment element aligned to the viewing element and the scanning device for optically indicating through the viewing element a location on the eye on which the pattern of the light will be located, but without projecting any alignment light onto the eye.

  • Publication number: 20070129775
    Abstract: System and method for generating patterns P of aiming and treatment light on target eye tissue (e.g. the retina) of a patient's eye. The system includes light sources for treatment and aiming light, a scanner for generating patterns of spots of the generated light, a controller, and a graphic user interface that allows the user to select one of several possible spot patterns, adjust the spot density and/or spot size, and apply patterns with fixed or varied density. The patterns can be formed of interlaced sub-patterns and/or scanned without adjacent spots being consecutively formed to reduce localized heating. Partially or fully enclosed exclusion zones within the patterns protect sensitive target tissue from exposure to the light.

  • Publication number: 20070129709
    Abstract: A system and method for treating ophthalmic target tissue in which a light source generates a beam of light, a scanner unit deflects the beam of light into a pattern, a beam delivery unit for delivering the pattern to ophthalmic target tissue. The light is either pulsed or moved across the target tissue such that the light pulses having a duration of, or the light dwells on any given point of target tissue for, between 30 ?s and 10 ms.

  • Publication number: 20070121069
    Abstract: A laser indirect ophthalmoscope (LIO) apparatus for photomedical treatment and/or diagnosis is presented. The LIO apparatus allows multiple spot ophthalmic surgery to be performed in a wider range of patient positions and less intrusively than currently available methods. The LIO apparatus utilizes a separate or integral beam multiplier that generates one or more optical beams via spatial and/or temporal separation, and an optical system that conditions and directs the one or more optical beams to a target to form a pattern. The LIO apparatus includes a headset, and is therefore wearable by the user (e.g., a physician).

  • Publication number: 20060195076
    Abstract: System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

  • Patent number: 7059503
    Abstract: A restraining and protection device for the protection and the restraint of neckstrap-suspended equipment used in the field, comprises a flexible cover of sufficient size to envelope most surfaces of the equipment. Attached to or associated with the cover is one strap that extend around the user's waist. A second strap is attached to the equipment so as to extend around the user's neck, or alternatively over one of the user's shoulder as desired. The ability to change the configuration of the straps is accomplished by providing an interconnection between the straps such that the waist strap can loop through the neck strap when the device is in a harness-type configuration and separated to change the device to an over-the-shoulder configuration with the equipment positioned proximate the user's hip.

  • Publication number: 20050286019
    Abstract: An apparatus and method for treating and/or diagnosing a patient's eye. A light source produces fixation light and procedure (treatment and/or diagnosis) light. A scanning device deflects the fixation light to produce a fixation pattern of the fixation light on the eye, and deflects the procedure light to produce a procedure pattern of the procedure light on the eye. A controller controls the scanning device such that the fixation and procedure patterns move relative to each other, and/or the fixation pattern dynamically changes.

  • Publication number: 20050288745
    Abstract: Optical scanning system and method for performing therapy on trabecular meshwork of a patient's eye, including a light source for producing alignment and therapeutic light, a scanning device for deflecting the alignment and therapeutic light to produce an alignment therapeutic patterns of the alignment and therapeutic light, and an ophthalmic lens assembly for placement over a patient's eye that includes a reflective optical element for reflecting the light patterns onto the trabecular meshwork of the patient's eye. The reflective optical element can be a continuous annular mirror (e.g. smooth or with multiple facets) to image the entire trabecular meshwork, or a reflective optical element that moves in coordination with the deflection of the beam. Visualization of the alignment and therapeutic patterns of light on the eye can be implemented by reflection thereof off a visualization mirror that transmits a portion of light emanating from the trabecular meshwork.

  • Patent number: 5320261
    Abstract: A restraining and protection device for the protection and the restraint of neckstrap-suspended equipment used in the field, comprising a flexible waterproof cover 10 of sufficient size to envelope most surfaces of the equipment. Attached to or part of the cover 10 is a length of elastomeric material 20 running along the edge of the cover 10. Attached to or associated with the edge of the cover are two attach tabs 40A and 40B, which enable attachment of the device 100 to the user or the user's clothing. As the restraining and protective device 100 is placed over the equipment and attached to the user or user's clothing, the elastic action of the cover 10 edge keeps the equipment protected, camouflaged, and restrained from swinging. This is accomplished by combining the actions of the elastomeric material along the cover 10 edge and the attachment means used to maintain the restraint and protection device's 100 position on the user or user's clothing.
