摘要：
Embodiments include a fiducial deployment system with a handle configured for actuation of same. A fiducial may include one or more protuberances configured to engage one or more slots in a needle of the system. The needle may be configured to deliver a plurality of fiducials to a target location in serial fashion, one at a time. In certain embodiments, echogenic placement of fiducials may present certain advantages. The handle includes a clutched-gear actuation mechanism configured for incrementally or otherwise controlled deploying one or more fiducials at a time by advancing a stylet through and/or retracting the body of a slotted needle in which fiducials are disposed with a fiducial protrusion extending into the needle slot, which also includes retaining structures that do not impede the needle lumen.
