| 20090099402 | IMPLANTS FOR USE IN BRACHYTHERAPY AND OTHER RADIATION THERAPY THAT RESIST MIGRATION AND ROTATION - In an embodiment a therapeutic member includes a solitary radioactive seed. The seed includes a metallic housing with radioactive material contained within the metallic housing. The metallic housing has a first longitudinal end and a second longitudinal end and a longitudinal length between the first and second longitudinal ends. A polymeric material is molded to completely and monolithically encapsulate the metallic housing of the solitary radioactive seed. The implantable therapeutic member is adapted to be implanted into patient tissue using a hollow needle. A portion of the molded polymeric material extends from one of the first and second longitudinal ends of the metallic housing to reduce a tendency of the seed to migrate and rotate within a patient's body after implantation of the member. The portion of the molded polymeric material, that extends from one of the first and second longitudinal ends of the metallic housing, causes the implantable therapeutic member to have a longitudinal length that is greater than the longitudinal length of the metallic housing. | 04-16-2009 |
| 20090149692 | IMPLANTS FOR USE IN BRACHYTHERAPY AND OTHER RADIATION THERAPY THAT RESIST MIGRATION AND ROTATION - In an embodiment a therapeutic member includes a single radioactive seed and is adapted to be implanted into patient tissue using a hollow needle. The seed includes a metallic housing with radioactive material contained within the metallic housing. A polymeric bio-adherent and/or bio-adhesive material surrounds at least a portion the housing of the single radioactive seed. The polymeric bio-adherent and/or bio-adhesive material reduces a tendency of the member to migrate and rotate within a patient's body after implantation of the member. | 06-11-2009 |
| 20090203953 | THERAPEUTIC MEMBER INCLUDING A RAIL TO RESIST MOVEMENT WITHIN A NEEDLE USED IN BRACHYTHERAPY AND OTHER RADIATION THERAPY - A therapeutic member for use in brachytherapy deliverable to an implant site by way of a needle comprises a single radioactive source encapsulated by a bio-absorbable material having an outer surface including one or more ribs encircling the single radioactive source, a leading edge endcap rib and a trailing edge endcap rib. The one or more ribs reduces a tendency of the member to migrate and rotate within a patient's body after implantation. The encapsulating material further includes a first rail formed from the bio-absorbable material extending at least from opposite sides of the outer surface of the encapsulating material along the longitudinal axis of the therapeutic member, and a second rail formed from the bio-absorbable material extending at least from opposite sides of the outer surface of the encapsulating material along the longitudinal axis of the therapeutic member, the second rail arranged in a plane substantially perpendicular to a plane in which the first rail is arranged. | 08-13-2009 |
| 20090312594 | DEVICES TO RESIST MIGRATION AND ROTATION OF IMPLANTS USED IN BRACHYTHERAPY AND OTHER RADIATION THERAPY - A therapeutic member for use in brachytherapy deliverable to an implant site by way of a needle comprises a single radioactive source encapsulated by a bio-absorbable material having an outer surface including one or more ribs encircling the single radioactive source, a leading edge endcap rib and a trailing edge endcap rib. The one or more ribs reduces a tendency of the member to migrate and rotate within a patient's body after implantation. The encapsulating material further includes a first rail formed from the bio-absorbable material extending at least from opposite sides of the outer surface of the encapsulating material along the longitudinal axis of the therapeutic member, and a second rail formed from the bio-absorbable material extending at least from opposite sides of the outer surface of the encapsulating material along the longitudinal axis of the therapeutic member, the second rail arranged in a plane substantially perpendicular to a plane in which the first rail is arranged. Another embodiment includes wings that selectively extend from an implant preventing movement of the implant. | 12-17-2009 |
| 20110263923 | SPACERS FOR USE IN BRACHYTHERAPY, RADIOTHERAPY, AND OTHER MEDICAL THERAPY - Spacers for use in brachytherapy, radiotherapy, and other medical therapy, which can be used to improve a patient's outcome, assist in treating difficult cases and/or combine multiple modalities that are currently performed separately into a single procedure. In accordance with an embodiment, a spacer is formed of an encapsulating material in a generally cylindrical or elongated shape. One or more regions are formed within the spacer for receiving and retaining therapeutic loads, such as radiation sources and/or pharmaceutical therapeutic loads, and/or any other substances that a physician might select to treat a patient, such as drug liquids, powder or particles (e.g., microparticles or nanoparticles), with the particles or powders combined with binders, such as polyacrylamide, that are selected to retain and gradually disperse the powder or particles at a desired rate. Such regions can be formed at various locations within the spacer, and can have various shapes depending on the particular design and intended usage, including, for example, bores, end cavities, wells, ports, slots and/or pockets. The outer surface of the encapsulating material can optionally include one or more fins, ribs or other physical protuberances or features that improve the fixity of the spacer when implanted within a patient's body. When implanted into the body, the spacer helps provide proper placement and spacing such as symmetrical and/or asymmetrical placement and spacing of the radiation sources and/or pharmaceutical therapeutic loads. | 10-27-2011 |
| 20120016176 | IMPLANTS FOR USE IN BRACHYTHERAPY AND OTHER RADIATION THERAPY THAT RESIST MIGRATION AND ROTATION - A therapeutic strand implant, for use in brachytherapy and deliverable to an implant site by way of a needle, includes a plurality of radioactive sources, and a polymeric material molded to encapsulate the radioactive sources. A space is defined by the polymeric material between each adjacent pair of the radioactive sources. A plurality of protrusions is defined by an outer surface of the encapsulating polymeric material. | 01-19-2012 |
