  • Patent number: 7791009
    Abstract: A system includes a plurality of scanning devices and light receivers, enabling a plurality of images of a site to be displayed using output signals produced in response to light from the light receivers. To avoid crosstalk caused by light receivers receiving light emitted by a plurality of scanning devices, different wavebands of light can be applied to different scanning devices, the received light can be filtered, or the light can be supplied to one scanning device at a time to multiplex either frame-by-frame, or pixel-by-pixel, or the light supplied to each scanning device can be modulated and the received light demodulated so that an image is produced in response to light from a single scanning device. Expensive components such as laser light sources, optical detectors, a controller, and processor can be shared by multiple imaging devices to minimize the cost of the imaging system.

  • Publication number: 20090137893
    Abstract: One or more scan illuminators and a plurality of light receivers are provided on the distal end of a tool or other component, so that a plurality of images of a site can be provided in response to output signals from the plurality of light receivers. The output signals from the plurality of light receivers are combined to produce an overall image of the site or a plurality of different images from disparate positions. The plurality of images can be viewed separately to produce a stereo or perspective view, or can be produced using different wavebands of light to provide enhanced information about the site that facilitates use of one or more tools or components at the site. The scan illuminator(s) and plurality of light receivers can be configured to be added to an existing tool or component.

  • Publication number: 20090028407
    Abstract: A scanning device for use in an endoscope or other applications can be driven to scan a region with one or more different scanning parameters during successive scanning frames. The scanning device, which can include an optical fiber or reflective surface driven by an actuator to move relative to one or more axes, can be provided with a drive signal that is different during successive scanning frames so that the scanning pattern can be caused to differ between the successive scanning frames by one or more of size, amplitude in at least one direction, depth, duration, shape, and resolution. Thus, different scanning frames can be employed for imaging, carrying out a diagnosis, rendering a therapy, and/or monitoring a site, using the appropriate scanning pattern, appropriate light source, and other parameters for each function that is carried out by the scanning device.

  • Publication number: 20090024191
    Abstract: A multi-cladding optical fiber includes a core that conveys visible light used by a scanner for imaging a site within a patient's body, and an inner cladding that conveys high-power light, such as infrared light, used for providing therapy to site. The distal end of multi-cladding optical fiber is driven to scan the site when imaging or rendering therapy using an actuator. High-power light is coupled into inner cladding at proximal end of optical fiber using several different techniques. Some techniques use an axicon to direct the high-power light into the inner cladding, while visible light is coupled directly into the core. Another technique uses a multimode optical fiber in a coupling relationship with the multi-cladding optical fiber, to transfer high-power light from a core of the multimode fiber into the inner cladding of the multi-cladding optical fiber.

  • Publication number: 20070299309
    Abstract: A scanning flexible endoscope includes a tether attached to a capsule. The tether controls a disposition of the capsule within a body lumen such as the esophagus. A scanning device in the capsule optically scans the adjacent tissue on the inside surface of the body lumen as the capsule is moved axially through the body lumen. A non-contact sensor responds to indicia on the tether to measure a relative position of the tether and the capsule in the body lumen. The indicia can be analog or digital in form and the sensor can be either magnetic, or optical. A wiper is optionally provided to remove bodily fluids from the tether when pulled from the body lumen past the sensor. A pulse of fluid can be delivered to the distal end of the tether to cause the body lumen to distend, facilitating free movement of the capsule in the lumen.

  • Publication number: 20070224395
    Abstract: Water-based adhesive compositions are improved by the incorporation of hollow polymeric microspheres having outer surfaces coated with one or more barrier materials such as calcium carbonate particles. The adhesive compositions exhibit enhanced rheology, sprayability, drying time, tack and storage stability as compared to analogous adhesives that are not modified with coated hollow polymeric microspheres. Such compositions are useful as both contact adhesives as well as wet bonding one-way adhesives.

  • Publication number: 20070129601
    Abstract: The present invention provides scanning beam devices that have one or more detectors positioned within a housing of the device. The detector(s) may be disposed anywhere within the housing to receive light reflected from the target area. In one embodiment, an optical assembly of the device transmits a first portion of the reflected light to a scanning element, and a second portion of the reflected light to the detectors. In another embodiment, the optical assembly is configured to transmit substantially all of the reflected light to the scanning element. In such embodiments, the scanning element will be adapted to allow the light to exit the scanning element and impinge on the detector(s) within the housing.

  • Publication number: 20070081168
    Abstract: Methods, systems, and devices can determine spatial relationships between a probe and a target surface. Specular reflections from the target surface vary dramatically with small changes in angle between the scanning beam and the target surface, and as the geometry of the beam scanner and light detector of the probe are often known, and as the angle of the light beam projected from a scanner for accurately generating an image, the pattern of spectral light reflected from the light beam directly back to the detector allows the distance between the probe and the target surface, and/or the angular relationship between the probe and the target surface, to be calculated.
