摘要： A transparent illuminated infusion cannula is provided for illuminating an area during eye surgery. An optical fiber may be spaced a certain distance away from the cannula such that fluid flow around the distal end of the fiber and into the transparent cannula may occur with a much higher flow rate than what had previously been possible. The fiber cannula airspace may be optimized so that the cross-sectional area of the fluid conduit remains substantially constant in order to achieve a best compromise between high light transmittance and high fluid flow rate.

摘要： Embodiments of endo-illuminators and related methods are disclosed. One embodiment of an illuminator can comprise a cannula defining a passage, an optical element disposed at an end of the cannula, and an optical fiber running through the passage with the distal end of the optical fiber in contact with the optical element. The optical fiber includes at least a heat preconditioned distal portion that terminates in the distal end that is in contact with the optical element. One embodiment of a method can comprise inserting an optical fiber through a proximal portion of a cannula and optical element assembly until the distal end of the optical fiber contacts the optical element, heating a distal portion of the optical fiber to between a softening temperature and a melting temperature for a period of time to cause the distal portion to axially shrink and moving the optical element so that the optical element is in contact with the distal end of the optical fiber when the distal portion of the optical fiber has axially shrunk. Moving the optical element so that the optical element is in contact with the distal end of the optical fiber when the distal portion of the optical fiber has axially shrunk can comprise applying a force to the cannula and optical element assembly to maintain the optical element in continuous contact with the distal end of the optical fiber while the optical fiber axially shrinks.

摘要： In embodiments of the invention, a plastic optical fiber is bonded to a high temperature distal part to form a thermally robust illumination probe. The distal part is short in length, is made of a high temperature material(s), has a proper shape for guiding light in a desired application, and may be coated with a reflective coating to ensure that the light rays trapped within the part do not escape when the side of the part is in contact with high refractive index or absorptive materials. The distal part may be made of high temperature material(s) such as high temperature plastic rods, glass optical fibers, and so on. The distal end may be tapered or sculpted to a desired configuration. The plastic optical fiber and the high temperature distal part may be joined, using an optical adhesive, inside a steel cannula, a plastic hub, an optical connector, etc.
