  • Patent number: 4614514
    Abstract: A microwave sterilizer for sterilizing a connector or coupling that interconnects a first conduit from a source of liquid to be infused into a living body to a second conduit implanted in the body. The apparatus of the invention comprises a housing having first and second members forming a guided wave structure adapted to be removably closed around the coupling or connector and further including first and second clamping means. The clamping means are adapted to clamp respective conduits and are operable to isolate a charge of the liquid within the connector. A microwave source is used to generate energy which in turn is coupled to the guided wave structure to cause heating of the liquid charge to a temperature level to cause sterilization so as to destroy substantially all form of bacteria therein. After a predetermined heating sequence, the apparatus is released and the bag side clamping means is first released so as to pass the sterilized charge of liquid into the source or bag.

  • Patent number: 4583556
    Abstract: A microwave applicator for applying microwave energy to living tissue for providing uniform heating without hot spots. The applicator includes a first electrical conductor and a second electrical conductor substantially shielding the first conductor in a transmission line configuration capable of propagating microwave energy in a frequency band suitable for heating living tissue. The first conductor has an unshielded portion extending a distance beyond the second conductor and there is additionally provided a coil as a third electrical conductor surrounding the extending portion of the first conductor and connected between the ends of the first and second conductors. The applicator is preferably configured for insertion through an opening into the body and includes a substantially smooth dielectric sleeve covering the coil of the third conductor.
