A cart or man-portable system and method for performing endoscopic procedures is provided. A portable display device, such as a laptop computer, is coupled to a handle comprising a miniature camera and fiber optic illumination subsystem. A sterile disposable portion is fitted over the illumination subsystem and inserted into a target area on a patient. Images of the target area are conveyed from the camera to the display device while an endoscopic procedure is performed, thus facilitating real-time diagnosis during the procedure.

Portable imaging system employing a miniature endoscope

One embodiment of the present invention is a unique system for measuring radiant energy in gas turbine engines, gas turbine engine components and gas turbine engine/component rigs. Another embodiment is a unique method for measuring radiant energy in gas turbine engines, gas turbine engine components and gas turbine engine/component rigs. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for measuring radiant energy. Further embodiments, forms, features, aspects, benefits, and advantages of the present application shall become apparent from the description and figures provided herewith.

System and method for measuring radiant energy in gas turbine engines, components and rigs

An endoscope has a fiber optic waveguide that transmits an image from a distal end to a proximal end, the waveguide having an outer diameter of less than 3 mm. A lens system is positioned at the distal end of the fiber optic waveguide. An imaging device is optically coupled to the proximal end of fiber optic waveguide. A disposable sheath extends about the fiber optic waveguide to provide a sterile barrier, and in a preferred embodiment the sheath includes an illumination channel. In a preferred embodiment, the lens system has a first lens element, a second lens element and an aperture stop.

Miniature endoscope with imaging fiber system

Disclosed is a method of forming an optical monitoring or transmitting light guide and a resulting apparatus that begins by bonding a bundle of optical fibers together using an epoxy and polishing the distal end of the bundle of optical fibers to create an optical aperture. The ratio of fiber size to binder particulate size of the epoxy used in the bonding process is sufficient to maintain the integrity of the bundle of optical fibers during the polishing of the distal end. The method positions the bundle of optical fibers into a protective sheath and a connector. The coefficient of thermal expansion of the epoxy used in the bonding process matches that of the connector. Once assembled, the invention positions the connector through the opening in the surface of a device, such that the distal end of the bundle of optical fibers is either recessed in, substantially flush with, or extends from the surface of the device through which the connector extends, depending on field-of-view requirements.

High temperature light guide

An apparatus including a handle; a first tubular body coupled to the handle and a second tubular body comprising a polymer material coupled to a distal end of the first tubular body and the distal end defining a guide face, wherein the first tubular body and the second tubular body are co-linearly aligned and collectively define a first lumen therethrough extending from an entry port to the guide face; wherein the second tubular body has a dimension adequate for insertion into a uterus of a human subject, and wherein the guide face comprises an outside diameter less than an outside diameter of the second tubular body. Also, a method of using a hysteroscope having a single operating channel.
