The deployment system (100) generally includes a deployment device configured to deploy at least one of a plurality of preloaded fiducials (102) to a target site within a patient via a rotational deployment mechanism (140). Each fiducial (102) generally includes a pellet-like body (104) having a groove (110) helically formed along an outer surface thereof and the deployment device includes a deployment catheter (120) having an internally threaded lumen (124) configured to engage the helical groove (110) of each fiducial (102) so as to allow rotational loading and deployment of each fiducial (102).
