    摘要： A device is provided for indicating when an intravenous needle has entered the vein through the use of a solid fiber optic mounted in the needle for showing visual instantaneous vein entry. The hub has a special light source connection to enhance the degree of light available for visualizing vein entry. The distal end of the fiber optic is polished to be the distal point of the needle. This polished distal end reflects color, such as red blood, immediately upon vein entry and exposure to blood, with the enhanced reflected light, to the magnifying system forming a part of the invention at the rear or proximal end of the fiber optic. The user observes immediate vein entry without any blood flow or exposure to blood.

    摘要： A light diffusing device for use in photodynamic therapy has a progressively distally increased exposed amount of core fiber defining a light emitting section. Excessive light energy emission is thus prevented access to proximal locations and provides an increased amount of available light energy at distal locations, thus permitting an even emission of light energy along the light emitting section.

    摘要： A method of manufacturing a medical instrument for diffusing light from an optical fiber is provided. The medical instrument includes an optical fiber having a proximal portion including a cladding layer surrounding the core and a distal portion having a diffuser tip comprising a protective coating made of acrylic or methylpentene surrounding the core, an optical coupling layer, and a sleeve. The protective coating strengthens the distal end of the optical fiber so that it can withstand a higher bending moment at failure than the uncladded core. At the same time, the protective layer has an index of refraction that is between the indices of refraction of the core and the optical coupling layer to direct light out of the core through to the optical coupling layer.

C. to destroy the cells of the endometrial lining while maintaining the average temperature of the myometrium at a temperature below approximately 42.degree. C. An apparatus for performing an endometrial ablation comprising an expandable membrane such as a balloon adapted to fit within the uterus and contact the endometrial lining when expanded. A web of light diffusing fiber-optic cables arranged on the outer surface the balloon such that the web contacts the endometrial lining of the uterus when the balloon is expanded. The fiber-optic web is connected to an array of high intensity lamps via a series of fiber-optic cables. The temperature of the endometrium is monitored by a of a series of temperature sensors arranged upon the surface of the balloon.

    摘要： As assembly is provided utilizing a combined catheter and introducer which cooperate to provide efficient infusion of drugs from the in-place assembly even on an intermittent basis with no return blood flow and without the need for any kind of involved valve assembly, or expensive heparin or saline blocks. The introducer is a short thin walled device which receives the catheter therein. The catheter has a plurality of very fine openings in the front end thereof with the openings having a dimension preventing blood backflow, but which allow passage of infusing medication for therapy because of the pressure imparted in the infusion flow of the drugs. The catheter is long enough so that the portion having the openings extends from the front end of the introducer. The front end of the catheter is blunt-ended to decrease trauma during insertion. The openings in the single lumen version extend around the entire circumference of the catheter to prevent the catheter tip from being blocked on one side and closed off. The assembly softens upon exposure to aqueous containing fluids. Moreover, the catheter swells upon insertion to extend to the internal walls of the introducer upon exposure to body fluids. The material of the assembly may include heparin, anti-infective ingredients and lubricants introduced into the polymer material forming the assembly. Finally, the assembly may be multi-lumen for infusing more than one medication through the assembly.

    摘要： An apparatus or method identifies and quantifies components of a sample medium filling a gap of an assembly of a transparent tube and a cylindrical float located substantially coaxially with the tube. This identification or quantification is made based on the high angle scatter and/or fluorescence of the medium. A polarized monochromatic or biochromatic light beam of the wavelength for which the tube is transparent projects through an optical focusing and/or scanning system to illuminate a section of the gap with a line of light positioned parallel to the longitudinal axis of the tube but displaced laterally therefrom. Means position and rotate the tube about its longitudinal axis producing a complete circumferential illumination of the sample medium sections in the gap. Light filtering and detecting means normal to the illumination axis detects high angle light scattering properties and/or fluorescence properties from the sample medium. Signal processing means analyzes the output from the detecting means to identify and quantify the sample medium.
