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

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.

Embeddable module for high output LED

A flexible infrared delivery apparatus useful for endoscopic infrared coagulating of human or animal blood and tissue or for other uses employs a source of infrared radiation which is not a laser and an elongated flexible fiber optic member which transmits radiation from the source to a contact portion at a distal end of the member and to a material such as human or animal tissue proximate the contact portion. The elongated member has an outer diameter which enables it to be inserted into and through an accessory channel of an endoscope to view the human or animal tissue or material to be treated with infrared radiation. A connector on the proximal end of the member allows the elongated member to be quickly connected to and disconnected from the apparatus where the member is aligned for receiving infrared radiation from the source. The contact portion defines a size, direction and shape of a radiation delivery area from the member to the human or animal tissue or material proximate the contact portion.
