Abstract
For implanting a therapeutic element, this needle assembly includes a cannula having a sharpened distal end, a line of elements in the cannula extending rearward from the distal end. A yieldable positioner including an absorbable plug positions the element more proximate the distal end a predetermined distance from the distal end. The positioner may be in various forms including an end plug, a tab in the cannula. The needle assembly may also be pre-loaded with the line of elements and be sterile and a distortion of the wall of the cannula. A stylet is reciprocable in the cannula and engages the end of the line of elements more remote from the distal end of the cannula.
