Abstract

A delivery system and method for interstitial radiation therapy uses a seed strand composed of a plurality of radioactive seeds (12) having projections (13) or indentations connected by a polymer. The seed strand is axially stiff and radially flexible and is bioabsorbablely in living tissue.
