The Burdette Medical Systems, Inc. Interplant™ system is used in planning and performing a prostate brachytherapy implant procedure to provide ultrasound probe alignment and radioactive seed implantation. The Interplant™ device will use standard 125-Iodine (125 I) or 103-Paladium (103 Pd) isotope permanent implant radiation seeds for the treatment of prostate cancer. The system will allow volume measurement and dose calculation, relevant prostate anatomy and dose visualization, and post-treatment seed localization.

The Interplant™ system for brachytherapy was developed to address the need for a comprehensive system and procedure for prostate seed implants. The Interplant in system compresses the requirement for separate multiple procedures into one online setting, This product integrates all of the delivery system components (needles, template guide, probe stepper) with the dose planning system for 125-Iodine (125 I) and 103-Paladium (103 Pd) implants. The system is designed for real-time dose planning in the Operating Room (OR) and for performing post-implant seed localization assessment. Real time ultrasound image plane acquisition with automatic probe position determination makes it possible to complete the image acquisition needed for dose planning within about a minute. The interplant™ system provides the needed components for seed implant procedures except the seeds themselves and uses existing ultrasound imaging equipment. This will enable the physician to focus on the procedure, providing immediate feedback for improved quality assurance. The Real-Time Brachytherapy Radiation Seed Implant Program and System includes all technology, computer software, and hardware, and methods associated with the implant of radioactive "seeds" or pellets in the prostate. System elements include the user interface, real-time image acquisition, image contouring, dose calculation and display software, dose volume histograms, isodose surface contours, post-implant seed localization, and the patient scheduling spreadsheet software. The System consists of a two-dimensional and three-dimensional image visualization and brachytherapy dose system employing 2D ultrasound imaging for use in radioactive seed implants of the prostate. The software for the brachytherapy seed implant and dose calculation system was developed on a Pentium-based processor with supporting graphics and digitizing hardware.
