BIO-ABSORBABLE BRACHYTHERAPY STRANDS

摘要

Provided herein are bio-absorbable strands for use in brachytherapy. In an embodiment, a plurality of discrete hollow bio-absorbable segments spaced apart from one another and encapsulated using a bio-absorbable material to form an elongated member configured to be implantable in patient tissue using a hollow needle. Each hollow bio-absorbable segment has a length, an outer periphery and an inner channel. Radioactive material is within at least a portion of the inner channel or coating at least a portion of the outer periphery of each hollow bio-absorbable segment. Contrast material is within at least a portion of the inner channel or coating at least a portion of the outer periphery of each hollow bio-absorbable segment.
