An illumination system for illuminating a lumen within a body of a patient comprising a tube having a proximal end and an opposed distal end and an internal chamber, the tube being configured for placement within a lumen of the body. The system also includes an illumination subsystem including an optical fiber that is sized and configured to seat within the internal chamber of the tube and a light source for generating light that is emitted by the fiber optic cable. The optical fiber, when mounted within the tube and when the light source generates light, emits light at the distal end of the tube so as to transilluminate the lumen and surrounding tissue so as to be able to locate the distal end of the tube within the lumen of the patient.

Positioning a tube in a lumen via transillumination

In one aspect, a light module is disclosed, which includes a housing providing a hollow chamber extending from a proximal end to a distal end, and a lens positioned in the hollow chamber, where the lens has a lens body comprising an input surface for receiving light from a light source and an output surface through which light exits the lens body, said lens further comprising a collar at least partially encircling said lens body. The light module further includes at least one shoulder on which the lens collar can be seated for positioning the lens within the housing. A light source, e.g., an LED, is coupled to the hollow chamber, e.g., at its proximal end, for providing light to the lens. In some embodiments, an optical window is disposed in the hollow chamber and is optically coupled to the output surface of the lens such that the light exiting the lens passes through the optical window before exiting the light module. In some embodiments, the shoulder can be formed as part of the housing. In other embodiments, the shoulder can be provided by a sleeve disposed in the module's housing.

Embeddable module for high output led

In one aspect, a handheld lighting system is disclosed, which comprises a handheld housing extending from a proximal end to a distal end, and a light module disposed at least partially in the housing. The handheld lighting system further includes a removable and replaceable power module that is coupled to the housing (e.g., it is at least partially disposed within the housing) and is electrically coupled to the light module, e.g., through a pair of electrical leads, for providing electrical power thereto. Light intensity from the light module may be controlled from a knob on the power module. Various adapters can allow the lighting system to attach to a multitude of medical, industrial, dental or veterinary endoscopes or other instruments.

Handheld mobile light source

An elliptical lens comprises a lens body having a proximal section and a distal section. The proximal section has at least one input surface for receiving light from a light source and the distal section has at least one output surface through which light exits the lens body. The proximal section further comprises a substantially elliptical peripheral surface receiving at least a portion of the light entering the lens body via the at least one input surface and directing at least some of the received light via total internal reflection to the distal section such that at least a portion of the light directed to the distal section exits the lens body through said at least one output surface. Optical assemblies having said elliptical lens may be embedded in medical devices such as endoscopes to provide efficient illumination.

The light module further includes at least one shoulder on which the lens collar can be seated for positioning the lens within the housing. A light source, e.g., an LED, is coupled to the hollow chamber, e.g., at its proximal end, for providing light to the lens.

Embeddable module for high output LED

A surgical headlight system includes an adjustable headband, a light assembly mounted to the headband, a motor assembly mounted to the headband and the light assembly, and electronic controller having a wireless transceiver therein, a power control circuit for varying electrical power delivered to a light source of the light assembly, a power source in electrical communication with the light assembly, the motor assembly, and the wireless transceiver, and a sterilizable wireless controller configured to transmit instructions to the wireless transceiver, the instructions causing the electronic controller to one or more of actuate at least one motor of the motor assembly to alter an orientation of the light assembly, adjust a diameter of an aperture of the light assembly, adjust a spacing between one or more condensing lenses and an objective lens, or operate the power control circuit to increase or decrease electrical power delivered to the light source.

Surgical headlight systems and methods for use

Wireless surgical headlight

A speaking valve for management of a patient's airway comprising a body rotatably and removably attachable to a tracheotomy tube, the body having a first end communicable with the tracheotomy tube and a second end distal from the first end, an offset opening formed in the second end, a ramp disposed within the body, a ball having a diameter disposed within the chamber, the ball being adapted to be guided up and down the ramp and able to partially close the opening in the second end of the body, and the body and hence the chamber therein, at the option and control of the patient, wherein the ball is adapted to move up and down the ramp opening and partially closing the opening in the second end of the body and, as selected, exhalation by the patient proceeds through the patient's upper respiratory system and facilitates speaking by the patient.

Adjustable and biased-open unidirectional speaking valve

Provided herein are water-tight, portable endoscopes that include the light and power source incorporated into a sealed compartment (also referred to herein as sealed canister) within the endoscope handle. The description also features water-tight, endoscope handles that include the light and power source incorporated into a sealed canister within the handle. In some embodiments, the sealed compartment contains all of the electronic components of the endoscope.

Portable endoscope

A compact, high-efficiency, high-power, solid state light source, comprising a high-power solid state light-emitting device, a light guide having a proximal light-receiving end proximate the light-emitting device and a distal light-transmitting end spaced farther from the light-emitting device, and a mechanical light guide fixing device coupled to the light guide near its proximal end, to hold the proximal end of the light guide in position near the light-emitting device.

Compact, high efficiency, high power solid state light source using a single solid state light-emitting device
