Methods and apparatus are provided for improved administration of brachytherapy in the treatment of prostate disease. More particularly, a prostate visualization device is provided comprising a disk-shaped bladder neck balloon that sealing engages and defines an enclosed space within a proximal region of a patients bladder. The device is preferably coupled to a catheter for injection of echo-contrast agent into the enclosed space to facilitate imaging of the patients bladder/prostate junction with an ultrasound system. The device may alternatively be radiopaque. Apparatus for selectively stiffening the catheter is also provided.

Methods and apparatus are provided for brachytherapy treatment of prostate disease. The apparatus comprises a housing, a plunger, a needle, and a lock. The plunger is rigidly affixed to the housing. The lock selectively restricts motion of the needle relative to the plunger. The needle comprises a screw thread that engages the housing or plunger. Rotation of the needle with respect to the housing/plunger causes distal advancement or proximal retraction of the needle with respect to the plunger, providing improved control over delivery of radioactive seeds to a diseased portion of a prostate.

Apparatus and methods for depositing radioactive seeds into a patients prostate are provided that include impedance measuring circuitry for detecting whether the distal end of an elongated needle extends into a patients bladder. The elongated needle includes two conductive traces and a lumen adapted to receive a column of radioactive seeds and spacers. The impedance measuring circuitry is coupled to the conductive traces of the elongated needle and provides a display indicative of the monitored impedance.

Methods and apparatus are provided for loading therapeutic materials into brachytherapy needles. The apparatus comprises an apparatus with chambers, and radioactive seed and spacer cartridges received therein. The apparatus may be used in conjunction with a standard brachytherapy needle coupled to the distal end of the apparatus. The plunger dislodges seeds and spacers from the cartridge chambers to load the needle with a predetermined packing arrangement.
