Abstract: Disclosed are apparatus and a method for sterilizing an internal surface of a lumen in a medical instrument, e.g., an endoscope. The apparatus is in the form of an elongated UVC light guide, e.g., an optic fiber, having a central longitudinal axis and which is configured to be extended down the lumen in the instrument, and a housing including a source of UVC light. The UVC light guide includes a distal end portion and is configured to carry UVC light internally from the source of UVC light to the distal end portion. The distal end portion includes a reflective surface for directing the UVC light radially outward with respect to the central longitudinal axis, whereupon when the UVC light guide is extended into the lumen in the medical instrument the radially directed UVC light impinges the internal surface of the lumen to sterilize it.

Abstract: Disclosed are a device and a method for irrigating a urinary catheter connected to a drainage bag. The device is configured to be selectively operated in any one of a drainage state, an irrigation state, and a disposal state without requiring its disconnection from the drainage bag. The device includes a port for receipt of a syringe holding an irrigation fluid. When in the drainage state the device enables fluid from the patient to passively drain into the bag. When in the irrigation state the device isolates the catheter from the bag and enables the irrigation liquid to be introduced from the syringe into the catheter and the patient's bladder to produce a contaminated fluid and also enables the contaminated fluid to be withdrawn back into the syringe. In the disposal state the device isolates the catheter from the drainage bag and enables the contaminated fluid to be introduced into the discharge bag.
