Title: X-ray probe sheath apparatus

Abstract: The invention is directed toward an X-ray treatment kit to be used in anX-ray treatment apparatus. The X-ray treatment kit includes at least oneof an improved biocompatible sheath or an improved probe, wherein anairflow path is maintained between the sheath and probe to allow airpresent within a void region of the sheath to escape as the probe isinserted therein. In various embodiments, the sheath includes a securingassembly which removably secures the sheath to the probe and provides anairflow path, e.g. an internally disposed annular ring with air shunts.Such a sheath may be used with a typical smooth probe to form an X-raytreatment kit. In other embodiments, an improved probe includes an airchannel formed substantially along its length. In such a case, theimproved probe may be used with a typical sheath, i.e., a sheath having asolid annular ring at its open end, to form an X-ray treatment kit.
