Abstract: A device, system, or method to aid in conducting brain activity analysis on an animal. The device may include a headrest for receiving at least part of the head of the animal, and a tube connected to the headrest for passing a treat to the animal through the tube so the animal is trained to position his or her head on the headrest and to maintain his or her head on the headrest for the time it takes to carry out the brain activity analysis. The animal is trained by the treat being passed to the animal through the tube. The device may be used with a replica to further train the animal prior to the device being used with a machine that may carry out brain activity analysis. The device may allow for the presence of stimuli and distractions as part of the training of the animal.

Abstract: A needle assembly particularly suitable for prostate brachytherapy anesthesia and biopsy anesthesia procedure. The needle assembly has a cannula with a tapered distal end and a hub attached to a proximal end of the cannula. The cannula is provided with a plurality of spaced-apart openings extending through a wall of the cannula between the proximal end and the distal end for creating a pre-determined pattern of distribution in variable cylindrical patterns along the needle tract.

Abstract: A radiotherapy stent device has a flexible, collapsible mesh body that can be expanded in a blood vessel of a patient to deliver radiation to the tissue surrounding the site of stent implantation. One or more hollow sleeves are secured on the body. The sleeves are loaded with radioactive material immediately prior to positioning of the stent in the vascular structure. As a result, the shelf life of the stent is substantially increased, and dosage of the radiation can be more precisely controlled.

Abstract: A device for installing a catheter in a patient's body for use in delivery of a radioactive source to and from the site of a tumor so that it may be shrunk. The device includes a catheter and apparatus for implanting the catheter through the tumor site so that the distal end of the catheter extends beyond the site, with the proximal end exposed externally of the body to permit entry and withdrawal of the radioactive source. A selectively deployable anchor at the distal end of the catheter is adapted to penetrate body tissue at the distal end beyond the tumor site when the anchor is deployed. Consequently, the distal end of the catheter will be securely anchored to maintain a substantially constant lineal depth from the proximal end of the catheter to the tumor site. The radioactive source can then be driven through the catheter to the tumor site to irradiate the tumor for a prescribed period, and then withdrawn.

Abstract: Remote controlled afterloader apparatus and method positions high activity radioactive sources through a catheter within a human body for treatment of cancerous tissue. The afterloader including an operating console and a remotely located wire driver. The wire driver includes active and dummy source wires and channels for the storage of such wires. Stepper motors precisely position the wires in response to computer control and data from wire position encoders. An emergency dc motor retraction system is provided for the active wire. A non-computerized cross-check interlock and emergency retraction system provides a high degree of safety against system malfunction. A turret is provided with safety locking and cross-checking systems to permit use of multiple catheters. The dummy wire is inserted into each catheter to verify catheter integrity prior to insertion of the active wire.

Abstract: A new and distinct cultivar of Euonymus plant named ‘Hayman’, characterized by its compact, upright and mounding plant habit; relatively rapid growth rate; freely branching habit; relatively small and fine leaves; and attractive autumn leaf color.
