Abstract: Methods and systems for a catheter access port cleaning, disinfection or sterilization device are disclosed. The catheter access port cleaning, disinfection or sterilization device may comprise, a first housing having a power source and control circuit; a second housing shaped to mate with a catheter and having a first ultra-violet light source mounted therein, the first housing wired to the second housing to power the light source. When activated, the ultra-violet light source emits ultra-violet radiation that is transmitted from the second housing to the catheter attached to a patient. In this way, the device provides an efficient system for cleaning, disinfecting or sterilizing an access port in the second housing while reducing patient infections.

Abstract: Various embodiments are described herein for a device, system, and method for identifying a location of an ingestible device within a gastrointestinal tract of a body. In some embodiments, the ingestible device includes a sensing unit with an axial optical sensing sub-unit located proximal to at least one end of the device, and a radial optical sensing sub-unit located proximal to a radial wall of the device, and may autonomously identify a location within the gastrointestinal tract. In some embodiments, the ingestible device includes optical illumination sources and detectors that operate at a plurality of different wavelengths, and may discern regions of a gastrointestinal tract by using the reflection properties of organ tissue and occasional particulates. In some embodiments, the ingestible device may sample fluid or release medicament based on a detected device location.

Abstract: Methods and systems are provided for sterilization. In one example, a device may include a body with a flexible tether and a receiving aperture having a central axis, the body forming an internal cavity, the cavity housing at least one circular battery with a central axis perpendicular to the central axis of the aperture; and a UV source positioned at an end of the receiving aperture. Various other additional features and alternative configurations are included.

Abstract: The present invention relates to light applicators, systems comprising light applicators, and methods for their use. One aspect of the invention provides a light applicator configured for contacting a portion of a subject's body surface and controllably applying light irradiation thereto. The light applicator comprises a housing, the housing comprising a treatment plate for contacting the portion of the subject's body surface and having one or more windows. One or more light emitters are disposed inside the light applicator and projecting toward the corresponding one or more windows of the treatment plate. A heat spreader plate is disposed inside the light applicator. One or more heat conducting members thermally connect the treatment plate to the heat spreader plate.

Abstract: Devices and methods for automatically maintaining disinfection of access sites of medical devices using ultraviolet light are disclosed. In one example approach, a device comprises a controller and an ultraviolet light source incorporated into a chamber of an enclosure which is closeable over access ports. In response to an adjustment of the enclosure from an open position to a closed position, the controller illuminates the ultraviolet light source for a predetermined first duration while the enclosure is maintained in the closed position. Following illumination of the ultraviolet light source for the first duration, the controller illuminates the ultraviolet light source for a predetermined second duration at predetermined time intervals while the enclosure is maintained in the closed position.
