1. A catheter sterilization system, comprising:
a linearly extending connector sized for insertion into the lumen of a catheter having inner sidewalls;
a sterilization head connected to the linearly extending connector, the sterilization head comprising:
at least one semiconductor LED emitter configured to emit UV light, the at least one semiconductor LED emitter comprising a light emission surface, the light emission surface arranged to be substantially parallel to a long axis of the catheter, and
forward and rear UV blocking caps, the at least one semiconductor LED emitter positioned between the forward and rear UV blocking caps, the forward and rear UV blocking caps extending above the light emission surface of the at least one semiconductor LED emitter to at least partially block the UV light emitted by the at least one semiconductor LED emitter from traveling along the long axis of the catheter.
