摘要:
Methods, apparatuses and systems are described for implanting a plurality offiducial markers into a tissue. Systems include a needle, a stylet sized toslide within a lumen of theneedle, and a multi-stop stylet spacer having stopping features configured toengage with the styletto stop the distal end of the stylet at one or more predetermined distancesfrom the distal end ofthe needle. Methods for implanting a plurality of fiducial markers into atissue are described andinclude inserting a needle preloaded with fiducial markers into a tissue,adjusting a multi-stop styletspacer from a safety position to a first deployment position, deploying afirst fiducial marker into thetissue, adjusting the stylet spacer from the first deployment position to asecond deploymentposition, and deploying a second fiducial marker into the tissue.
