ABSTRACT:
A delivery system and method for interstitial radiation therapy uses a seed strand composed of a plurality of tubular shaped, hollow radioactive seeds with a bore. The seed strand as assembled with a material provided in the bore and between the spaced seeds is axially stiff and radially flexible and is bioabsorbable in living tissue.
