Abstract: A patient restraint member is provided for medical procedures, such as radiation therapy. The restraint member is formed from a sheet of thermoplastic material that can be softened upon heating so as to be formable into a shape corresponding to a patient's body part to be restricted and setting upon cooling to retain the shape. The sheet includes spaced apart groups of perforations which minimize shrinkage during the formation process. The sheet also includes solid bands extending between the groups of perforation to provide rigidity and strength to the formed sheet.

Abstract: A motor assisted swivel is disclosed which aids in proper rotation of a swivel in a tether system for animal testing. The swivel may have any number of fluid conduits or electrical or optical leads. A switching mechanism determines a direction of rotation of the tether and activates a motor to rotate the swivel in the direction of rotation. When rotation of the tether stops, further rotation of the swivel causes the switching mechanism to deactivate the motor. The switching mechanism may include a hinged connector with magnets on each side and reed switches to sense movement of the connector about its hinge.

Abstract: A large capacity seed cartridge is provided for a radiation therapy seed applicator. The seed cartridge is adapted for use with the Mick applicator, or other conventional applicators. The cartridge includes a housing with a seed drum mounted therein. A seed track extends around the seed drum. A spring operatively urges the seed in the track towards a discharge opening in the seed drum. A seed pusher rod in the applicator pushes each seed out of the opening and into the needle which is positioned in the patient, such that the seed is implanted into the body of a patient. The seed cartridge can be quickly and easily installed in the applicator and holds 120 radioactive seeds, or more.

Abstract: A radiation table insert comprises a perimeter frame having at least one open side and a radiation transparent rigid grid mounted within said perimeter frame, to provide an oblique lateral treatment port along the open side of said frame. The open side of the carbon fiber grid is provided with a down-turned flange grid that provides the structural support to help prevent sag and to provide a radiotranslucent window that eliminates potential radiation build-up. This design is particularly important in meeting the challenges of arch or rational therapy programs that require later oblique treatment angles.
