Abstract
A seeding needle lumen is adapted to receive a string of seeds and spacers. A dimple is formed in the seeding needle near its distal end and a protuberance formed by the dimple extends into the lumen. A hollow housing formed of a bio-absorbable, flexible and resilient material is positioned within the lumen in abutting relation to a trailing end of the protuberance. The hollow housing has an external diameter slightly less than a diameter of the lumen so that the hollow housing cannot slide past the protuberance and an internal diameter adapted to slidingly receive a seed or spacer positioned at a leading end of a string. The flexible and resilient material is momentarily deformable so that the hollow housing may squeeze past said protuberance when a stylet is maintained in a fixed position in abutting relation to a trailing end of the seeds and spacers when the seeding needle is withdrawn.
