Abstract:
1. A fiducial deployment needle system comprising: an outer sheath having a longitudinal outer sheath lumen; an elongate fiducial-carrying member disposed coaxially through the outer sheath lumen; a plurality of fiducials disposed along a distal portion of the fiducial-carrying member, where each of the fiducials includes a central aperture engaged around the fiducial-carrying member; and a movable structure configured to advance the fiducials distally relative to the fiducial-carrying member; wherein the fiducial-carrying member is configured as a delivery cannula, and the movable structure is configured as a flexible elongate deployment member including a first length disposed along an external surface of the delivery cannula and a second length, continuous with the first length, extending around a distal end of the delivery cannula into the delivery cannula lumen, wherein the flexible elongate deployment member includes at least one engagement structure proximally located relative to at least one of the plurality of fiducials such that distal-ward advancement of the first length and proximal-ward movement of the second length will distally advance, in conveyor-like fashion, the at least one of the plurality of fiducials.
