Therapeutic member including a rail used in brachytherapy and other radiation therapy
First Claim
1. A therapeutic member for use in brachytherapy deliverable to an implant site by way of a needle, comprising:
- a radioactive source;
an outer structure encapsulating at least a portion of said radioactive source;
said outer structure including a plurality of protrusions that reduce a tendency of the therapeutic member to migrate and rotate within a body of a patient after implantation;
said protrusions including first and second radial ribs encircling said radioactive source and spaced apart from one another along at least a portion of a longitudinal axis of said radioactive source; and
said outer structure also including one or more longitudinal rails;
wherein at least a portion of each said longitudinal rail extends between and thereby ties together said first and second radial ribs.

Abstract
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.

16. A therapeutic member for use in brachytherapy deliverable to an implant site by way of a needle, comprising:
-
a radioactive source; an outer structure molded to encapsulate the radioactive source and including (a) a first end cap rib located at a first longitudinal end of said outer structure; (b) a second end cap rib located at a second longitudinal end of said outer structure; (c) one or more radial ribs encircling said radioactive source between said first end cap rib and said second end cap rib; and (d) one or more longitudinal rails that tie together said first end cap rib, said one or more radial ribs encircling said radioactive source, and said second end cap rib. - View Dependent Claims (17, 18, 19)

20. A therapeutic member for use in brachytherapy deliverable to an implant site by way of a needle, comprising:
-
a radioactive source; and a polymeric material molded to encapsulate said radioactive source; wherein an outer surface of said polymeric material defines at least two radial ribs spaced apart from on another and encircling said radioactive source and one or more longitudinal rails that tie together said at least two radial ribs; and wherein a thickness of the encapsulating polymeric material varies such that the thickness is greater where there is at least one of a said radial rib and a said longitudinal rail than where there is not at least one of a said radial rib and a said longitudinal rail. - View Dependent Claims (21)
