摘要： Endoscopes, multicore endoscope fibers and configuration and operation methods are provided. The fibers may have hundreds or thousands of cores and possibly incorporate working channel(s) and additional fibers. The fiber may be used at different optical configurations to capture images of tissue and objects at the distal tip and to enhance a wide range of optical characteristics of the images such as resolution, field of view, depth of field, wavelength ranges etc. Near-field imaging as well as far-field imaging may be implemented in the endoscopes and the respective optical features may be utilized to optimize imaging. Optical elements may be used at the distal fiber tip, or the distal fiber tip may be lens-less. Diagnostics and optical treatment feedback loops may be implemented and illumination may be adapted to yield full color images, depth estimation, enhanced field of views and/or depths of field, and additional diagnostic data.

摘要： A probe 3 includes an irradiation fiber 34, a light-collecting fiber 35, a covering member 37 that covers a side face of the fiber, a cap 40 that covers a distal end of the probe, a white plate 42 that is provided on a surface of the cap 40 facing the distal end of the fiber and that is used in calibration measurement by light emitted from the distal end of the fiber, and an adhesive member that adheres the cap 40 to the distal end of the probe 3 and is made of an adhesive member 43 having an adhesive strength with respect to the covering member 37, the adhesive strength decreasing by application of heat. In a light-irradiated portion of the white plate 42, heat is generated by being irradiated with light, and the adhesive 43 is melted by conduction of the generated heat from the white plate 42 to the adhesive 43.

摘要： 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.

摘要： This document discusses, among other things, a connector for an optical imaging probe that includes one or more optical fibers communicating light along the catheter. The device may use multiple sections for simpler manufacturing and ease of assembly during a medical or other procedure. Light energy to and from a distal minimally-invasive portion of the probe is coupled by the connector to external diagnostic or analytical instrumentation through an external instrumentation lead. Certain examples provide a self-aligning two-section optical catheter with beveled ends, which is formed by separating an optical cable assembly. Techniques for improving light coupling include using a lens between instrumentation lead and probe portions. Techniques for improving the mechanical alignment of a multi-optical fiber catheter include using a stop or a guide.
