Abstract
A flexible, continuous, axially elastic interstitial brachytherapy source is capable of elongating, shrinking and/or flexing in response to changes in the size and/or shape of a tumor, tumor bed, lesion or other tissue with which the source is in contact. In one embodiment, the source is in the form of a wire coil. The flexible and expandable/contractible nature of the source allows it to provide therapeutically effective treatment to dynamic tissue as it swells, shrinks and/or changes in shape.
