| 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 |
| 20090124894 | MARKERS FOR USE IN BRACHYTHERAPY AND OTHER RADIATION THERAPY THAT RESIST MIGRATION AND ROTATION - In an embodiment, an implantable marker, which is adapted to be implanted into patient tissue using a hollow needle, includes a marker body including a radiopaque material and a polymeric material that encapsulates at least a portion of the marker body. In an embodiment, an outer surface of the encapsulating material includes one or more protrusions to reduce a tendency of the marker to migrate and rotate within a patient's body after implantation. | 05-14-2009 |
| 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 |
| 20100210892 | IMPLANTS INCLUDING SPACERS FOR USE IN BRACHYTHERAPY AND OTHER RADIATION THERAPY THAT RESIST MIGRATION AND ROTATION - A brachytherapy implant includes a plurality of protrusions to reduce a tendency of the implant to migrate and rotate within a patient's body after implantation. Embodiments of the present invention are directed to spacers that resist migration and rotation. This abstract is not intended to be a complete description of the invention. | 08-19-2010 |

| 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 |
| 20090216063 | BIO-ABSORBABLE BRACHYTHERAPY STRANDS - Provided herein are bio-absorbable strands for use in brachytherapy. In an embodiment, a plurality of discrete hollow bio-absorbable segments spaced apart from one another and encapsulated using a bio-absorbable material to form an elongated member configured to be implantable in patient tissue using a hollow needle. Each hollow bio-absorbable segment has a length, an outer periphery and an inner channel. Radioactive material is within at least a portion of the inner channel or coating at least a portion of the outer periphery of each hollow bio-absorbable segment. Contrast material is within at least a portion of the inner channel or coating at least a portion of the outer periphery of each hollow bio-absorbable segment. | 08-27-2009 |
| 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 |
