Patent ID: 8795146

Claim:
An implant configured and adapted to be implanted in a patient at least one of between radioactive seeds and containing one or more radioactive seeds, comprising: a polymeric cylindrical body with a longitudinal axis, wherein a first bullet shaped polymeric rounded end and a second bullet shaped polymeric rounded end extend from said polymeric cylindrical body, said first bullet shaped polymeric rounded end including a first inwardly facing sidewall which is perpendicular to the longitudinal axis, said second bullet shaped polymeric rounded end including a second inwardly facing sidewall which is perpendicular to the longitudinal axis, with the first inwardly facing sidewall facing said second inwardly facing sidewall; a first polymeric rib and a second polymeric rib completely encircling said polymeric cylindrical body and with said first and second polymeric ribs located between the first inwardly facing sidewall and the second inwardly facing sidewall, with said first polymeric rib spaced from said first bullet shaped polymeric rounded end, and said second polymeric rib spaced from said first polymeric rib, and said second bullet shaped polymeric rounded end spaced from said second polymeric rib; wherein said first bullet shaped polymeric rounded end, said second bullet shaped polymeric rounded end, said first polymeric rib and said second polymeric rib all have the same circumference; said first polymeric rib including third and fourth sidewalls that are perpendicular to said longitudinal axis; said second polymeric rib including fifth and sixth sidewalls that are perpendicular to said longitudinal axis; wherein said implant is adapted to be urged out of a needle to be implanted in a patient and wherein said implant is adapted to receive tissue between the first inwardly facing sidewall and said third sidewall, between said fourth sidewall and said fifth sidewall, and between said sixth sidewall and said second inwardly facing sidewall, when the implant is implanted in a patient in order to reduce the tendency of the implant to migrate within the patient's body.
