<p>A delivery device (10) provides for the attachment of a special intravascular radiation therapy catheter (not shown), through which a drive mechanism (48) extends, and retracts a ribbon (38). In the unlikely event this mechanism (48) fails during retrieval, stranding the radioactive elements (not shown) outside the containment area (44), A back-up method of retrieving the ribbon (38) is available.</p> |
