ABSTRACT:
An ultra-thin iridium source is used for the treatment of cancerous tissue, particularly in areas of the human body, such as the brain, where minimization of trauma to adjacent tissue is a high priority. The source is formed of a relatively pure iridium seed encapsulated in the end region of a relatively pure unitary platinum delivery wire. The relatively pure iridium source is irradiated to a high activity level (e.g. 10 curie) even though having a short overall length (e.g. 10 millimeter) and ultra-thin diameter (e.g. about 1/8 millimeter ). The platinum delivery wire defines a substantially uniform ultra-thin cross section of approximately 0.5 millimeter diameter. The iridium source is formed within the unitary platinum delivery wire without resort to welding or other inherently unreliable attachment systems. Delivery of the high activity pure iridium source to treatment area is achieved using remote afterloader equipment.
