Radioactive therapeutic device

A brachytherapy source delivery device comprising:

• a first tissue-piercing leg having proximal and distal ends;
• a second tissue-piercing leg having proximal and distal ends, wherein the proximal ends of the first and second tissue-piercing legs are joined at a span section in a first angular orientation with respect to each other;
• and
• a carrier element formed at, or attached to, the span section, the carrier element configured to support a radioactive brachytherapy source;
• each of said first and second tissue-piercing legs comprising a straight and longitudinally extending leg each having at the distal end thereof a barb, and wherein the respective barbs extend in a direction toward each other;
• said span section comprising only an arcuate span section having respective ends that are contiguous with the respective proximal ends of the first and second tissue-piercing legs;
• wherein each of the first and second tissue-piercing legs have a like straight length that is greater than an arcuate length of the arcuate span section.
