Abstract
A brachytherapy device includes a radiation source and a multi-cannula delivery system for implantation of the radiation source into a body tissue site. The radiation source may be, for example, a substantially straight round wire, a substantially straight flat wire, a detented wire, an embossed wire, a bristled wire, a shaped resilient wire, a twisted round wire, a twisted flat wire, or a coil with or without an inner core, and is adapted for implantation into a body tissue site and for delivery of radiation to the body tissue site. The multi-cannula delivery system includes an outer cannula, an outer stylet, an inner cannula, and an inner stylet. Different configurations of the radiation source according to embodiments of the invention improve distribution of the radiation field in the longitudinal direction and resistance to migration of the radiation source inside a patient's body. The multi-cannula delivery system provides for faster and more accurate placement of the radiation source.
