| 20080269540 | SEED CARTRIDGE ADAPTOR AND METHODS FOR USE THEREWITH - Provided herein are adaptors that enable a seed cartridge that is configured to be used with a first type of needle having a locking hub to instead be used with a second type of needle having a cylindrical hub. Such a seed cartridge has a hub at its distal end that is configured to attach to the locking hub of the first type of needle. The adaptor includes a proximal portion configured to removably attach (and in specific embodiments lock) to the hub at the distal end of the seed cartridge. The adaptor also includes a distal portion configured to removably attach to the cylindrical hub of the second type of needle. A central portion of the adaptor connects the proximal and distal portions of the adaptor. A bore extends through the adaptor and allows seeds and optional spacers to be transferred from the seed cartridge into a hollow cannula of the second type of needle. Also provided herein are methods for using such adaptors. | 10-30-2008 |
| 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 |
| 20090124846 | ANCHOR SEED CARTRIDGE FOR USE WITH BRACHYTHERAPY APPLICATOR - In an embodiment, a brachytherapy device includes a cartridge adapted for use with a brachytherapy applicator. A plurality of anchor seeds are stacked parallel to one another within the cartridge. Each anchor seed includes a radioactive seed that is at least partially encapsulated by a polymeric material. Additionally, each anchor seed can include at least one protrusion on an outer surface of the encapsulating polymeric material to a reduce a tendency for the anchor seed to migrate and rotate within a patient's body after the anchor seed is implanted. | 05-14-2009 |
| 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 |
| 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 |
| 20100121130 | DELIVERY SYSTEM AND METHOD FOR INTERSTITIAL RADIATION THERAPY - A prescription method of treating tissue comprises the steps of accepting a prescription tissue treatment plan for the tissue to be treated, positioning seeds relative to each other per the prescription tissue treatment plan such that the positions of seeds relative to each other is only established by the prescription tissue treatment plan, and creating a treatment strand by heating and cooling a material to position the plurality of treatment seeds in the material. The prescription tissue treatment plan specifies a number and a spacing of the seeds to be provided in the treatment strand, the spacing of the treatment seeds being unrestricted by any use of spacers and independently set by and according to the prescription tissue treatment plan. | 05-13-2010 |
