Abstract: An apparatus is provided to fix a thermoplastic mask to a patient. The apparatus includes a member formed to be positioned adjacent a cranio facial bone, a fixation member coupled to the member, and a fastener plate. The fastener plate couples the mask to the fixation member so that the member is in a fixed position relative to the mask.

Abstract: An apparatus for use in optimizing radiation dose distributions to a rectum and a bladder of a patient during the treatment of malignancies of female genitalia is provided in accordance with the present invention. The apparatus includes a colpostat intracavitary implant including a housing portion adapted to receive a radiation source therein and a jacket. The jacket defines a cavity sized to receive the housing portion. The jacket is configured to selectively expand in volumetric size to move the rectum and the bladder away from the radiation source.

Abstract: A system of a subcutaneous venous access device or injection port and needle, wherein the port includes a self-closing septum for repeatedly and periodically receiving a predetermined section of an injection needle, and which septum covers an injection-receiving chamber in communication with a vein. The needle has a non-coring (e.g., "Huber" or removable stylet) point and means for providing a locking configuration such as increased diameter but smooth outer surface of the needle port-received section, which, when properly inserted, is within the septum or chamber, so as to more securely affix the needle within the port and prevent or decrease the incidence of accidental partial or total removal and the resulting undesirable subcutaneous infiltration of chemicals during infusion.
