Abstract: An intravenous port and method of sterilizing an intravenous port via an ultraviolet (UV) light source are provided. The port comprises a catheter capable of being inserted into a blood vessel and an access head having a signal receptor, such as an antenna, and ultraviolet light source such as for example a light emitting diode (LED). A transmitter is further provided for delivering an electrical signal from a power source to the UV light source. The light source is suitable for directing UV light of a predetermined wavelength through the lumen of the catheter in a manner that incapacitates microorganisms residing in the catheter. The UV light is transmitted through the lumen of the catheter through a sterile solution that can be inserted into the port.
