Patent ID: 8855747

Claim:
A fiducial deployment system comprising: a needle including a generally tubular cannula body defining a needle lumen disposed through at least a lengthwise portion of the cannula body and a distal needle region that includes a distal region aperture opening to the needle lumen, which aperture is configured to allow passage therethrough of a fiducial; and a plurality of fiducials including: at least one first fiducial and at least one second fiducial, where the at least one first fiducial is engaged with the at least one second fiducial; where the at least one first fiducial and the at least one second fiducial are disposed along a common collinear axis; and where the distal region aperture, the at least one first fiducial, and the at least one second fiducial are configured such that advancing the at least one first fiducial through the distal region aperture will facilitate complete disengagement of the at least one first fiducial from the at least one second fiducial, such that the second fiducial is separately and independently located apart from the first fiducial; where engagement of the at least one first fiducial with the at least one second fiducial comprises attachment of the at least one first fiducial to the at least one second fiducial by a non-elastic material, different than the material comprising the at least one first fiducial and the at least one second fiducial, wherein said non-elastic material will separatingly break and disengage the at least one first fiducial away from the at least one second fiducial when the at least one first fiducial is angularly offset from the common collinear axis.
