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.
Claims20
A medical clip comprising:
- a pair of longitudinally extending legs that each have a tissue piercing distal end;
- an interconnecting span section that connects proximal ends of the respective pair of longitudinally extending legs;
- the pair of longitudinally extending legs disposed about a longitudinal axis;
- a carrier element supporting a radio-active source;
- said interconnecting span section comprising a helical coil structure of multiple successive coil loops having a longitudinal axis and forming a cylindrical inner cavity in which the carrier element is supported;
- the longitudinal axis of the helical coil structure extending substantially orthogonal to the longitudinal axis defined between the pair of longitudinally extending legs.
