摘要:
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 patients 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.
