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