Abstract
Permanent brachytherapy seed implants in which the seeds are enclosed within a stiff, braided, absorbable suture material promise faster preparation and less seed migration than alternating loose seeds and spacers. The first commercial product of this sort, I-125 Rapid Strand™ by Amersham Healthcare, often jams in the implant needles when moisture from body fluids softens and swells the suture material. This problem is eliminated by sealing the tips of the implant needles with a durable, moisture-resistant plug formed by dipping the needles into molten Anusol-HC® suppositories. There have been no instances of jammed needles in using this technique in 30 patients and no noticeable side effects from the residual sealing material.
