Delivery system and method for interstitial radiation therapy using seed strands constructed with preformed strand housing

A device to be used with therapeutic seeds in order to assembly a therapeutic element, which device comprises:

• a first elongated half-shell having a half-bore adapted for receiving the therapeutic seeds;
• a second elongated half-shell having a half-bore which can mate with the first elongated half-shell in order together to define a full bore that is adapted to contain the therapeutic seeds;
• and
• wherein said first and second elongated half-shells are made of a biocompatable, and bioabsorbable material.

A device to be used with therapeutic seeds in order to assembly a therapeutic element, which device comprises:

• a first elongated half-shell having indentations adapted for receiving the therapeutic seeds;
• a second elongated half-shell which can mate with the first elongated half-shell in order together to contain the therapeutic seeds;
• and
• wherein said first and second elongated half-shells are made of a biocompatable, and bioabsorbable material.

A therapeutic element comprising:

• first and second elongate half-shell members made of polymeric material;
• a plurality of therapeutic seed elements;
• wherein
• said plurality of therapeutic seed elements are placed between said first and second half-shell members, and
• said first and second elongate half-shell members are joined and form an elongated member by encapsulating said plurality of radioactive seed elements.
