  • Patent number: 8560052
    Abstract: Echogenic medical devices, methods of fabrication and methods of use are disclosed. The device can be adapted to be inserted into a patient. The echogenic construction can be incorporated into the device at the time of fabrication providing acoustic impedance different from that of the surrounding biological tissue or fluid. The medical device is designed for use with an ultrasound imaging system to provide real-time location of the insertion and guidance at the time the device is implanted in a patient, such as in brachytherapy. Following placement of the device the position can be evaluated over time to insure the device remains in proper alignment and functional. Furthermore, the device is designed to incorporate a spacer element at one or both ends to provide separation between radioactive elements.

  • Patent number: 8298129
    Abstract: A selectively loadable/sealable bioresorbable carrier assembly for retaining and positioning elements used in brachytherapy procedures comprises a bioresorbable tube having a closed distal end and a proximal open end. The bioresorbable tube is loaded with a selectable arrangement of elements, including at least one radioactive seed, through the proximal open end. After the bioresorbable tube is selectably loaded, the bioresorbable tube is heat sealed at a sealing position adjacent a proximalmost element. Once sealed, the bioresorbable tube maintains the arrangement of elements throughout the treatment duration.

  • Patent number: 7959548
    Abstract: An automated implantation system assists the implantation of low dose radioisotope seeds in a patient as part of a brachytherapy procedure. A Z-axis automated motion control system and an X-Y axis automated motion control system control a needle assembly. The X-Y axis automated motion control system positions an insertion axis of the needle assembly relative to the patient. The Z-axis automated motion control system selectively moves the needle assembly along the insertion axis to implant at least one radioisotope seed. This process is repeated for a plurality of locations on a base plane perpendicular to the insertion axis. Preferably, the radioisotope seeds are contained in a replaceable cartridge and the needle assembly is also replaceable.

  • Publication number: 20100056842
    Abstract: A brachytherapy multiple needle loading device and method are provided. The device allows multiple implantation devices to be loaded at the same time and has a gating retention mechanism that allows the user to load sources into implantation devices at a desired rate. A packaging unit of the device has a two part configuration that allows removal of implantation devices that have been loaded with sources. The packaging unit may be opaque or translucent to allow visual inspection of the sources.
