Abstract
A system for brachytherapy is provided. The system includes an implantation device having a tubular member, a radioactive source within the member, and a socket at opposing ends of the tubular member. A plurality of implantation devices may be joined into an assembly by use of a spacer positioned within the sockets of adjoining devices. The device may be deployed at an implantation site by use of a delivery mechanism, such as needle. The presence of the tubular members and spacers minimizes movement of the radioactive source subsequent to deployment, so as not to alter dose distribution for subsequent irradiation.
