US 11,957,932 B1 · Radioactive therapeutic device

Abstract

A brachytherapy source delivery device includes 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. The distal ends of the first and second legs can be curved inward toward each other to pierce a tissue when engaged toward each other into a closed position. The first and second tissue-piercing legs can be formed of a wire having a circular cross-sectional or non-circular cross-sectional shape. The carrier element can be tangentially attached to the span section. Each of the legs have a length that is greater than the length of the span section.

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 the first and second tissue-piercing legs including a straight distal leg section and a contiguous straight proximal leg section;
the contiguous straight distal leg section and straight proximal leg section of each tissue-piercing leg joined so as to form respective and facing obtuse angles therebetween;
wherein the distal ends of the first and second legs are curved inward toward each other to form respective barbs to pierce a tissue when engaged toward each other into a closed position;
and
wherein for each tissue-piercing leg the proximal leg section is shorter in length than the distal leg section.
