Publication number: 20040220444Abstract: Methods and apparatus are provided for improved brachytherapy treatment of prostate disease. The apparatus provides for angular reorientation of a needle template with respect to an ultrasound probe during brachytherapy administration. Angular reorientation is expected to beneficially overcome anatomical constraints, such as skeletal structures, that may limit a medical practitioner's ability to deliver radioactive brachytherapy seeds into a prostate in proper alignment.Type: ApplicationFiled: May 28, 2004Publication date: November 4, 2004Applicant: NeoSeed Technology LLC.Inventors: Michael Hogendijk, Ryan P. Boucher

Publication number: 20040087828Abstract: Methods and apparatus are provided for loading therapeutic materials into brachytherapy needles. The apparatus comprises a loading tube with a lumen and two transverse slots, and radioactive seed and spacer cartridges slidably received within the transverse slots. The apparatus may be used in conjunction with a standard brachytherapy plunger and needle coupled to, respectively, the proximal and distal ends of the loading tube. The plunger dislodges seeds and spacers from the cartridge chambers to load the needle with a predetermined packing arrangement.Type: ApplicationFiled: October 23, 2003Publication date: May 6, 2004Applicant: NeoSeed Technology LLCInventors: Thomas C.

Patent number: 6422997Abstract: 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 patient's bladder. The device is preferably coupled to a catheter for injection of echo-contrast agent into the enclosed space to facilitate imaging of the patient's bladder/prostate junction with an ultrasound system. The device may alternatively be radiopaque. Apparatus for selectively stiffening the catheter is also provided.Type: GrantFiled: August 25, 2000Date of Patent: July 23, 2002Assignee: Neoseed Technology LLCInventors: Thomas C. Green, Michael J.

Patent number: 6398711Abstract: Methods and apparatus are provided for improved brachytherapy treatment of prostate disease. The apparatus comprises a needle template mount for use with standard brachytherapy apparatus. The mount provides for angular reorientation of a needle template with respect to an ultrasound probe during brachytherapy administration. Angular reorientation is expected to beneficially overcome anatomical constraints, such as skeletal structures, that may limit a medical practitioner's ability to deliver radioactive brachytherapy seeds into a prostate in proper alignment. The mount comprises an arc slot in which the template may translate to achieve angular reorientation. A guide tube is also provided to ensure straight advancement of brachytherapy needles.Type: GrantFiled: August 25, 2000Date of Patent: June 4, 2002Assignee: Neoseed Technology LLCInventors: Thomas C.

Patent number: 6361487Abstract: 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.Type: GrantFiled: March 9, 2000Date of Patent: March 26, 2002Assignee: Neoseed Technology LLCInventors: Thomas C.
