Abstract
A needle biopsy system for marking a sampling site is described.
Claims28
A needle biopsy system, comprising:
- a sampling portion locatable inside the body and including a stylet having a sampling region, a cannula, and a marker lumen extending from a proximal end of the stylet to a marker exit opening, the stylet and cannula being relatively moveable along the stylet axis to position the cannula over the sampling region, and
- a sample marker locatable in and releasable from the sampling portion;
- wherein the marker lumen is between the stylet and cannula.
A method of biopsy treatment, comprising:
- providing a needle biopsy device including a sampling portion with a stylet having a sampling region, a cannula, and a marker lumen extending from a proximal end of the stylet to a marker exit opening, the stylet and the cannula being relatively moveable to position the stylet over the sampling region, wherein the marker lumen is between the stylet and cannula,
- inserting the stylet into a tissue mass,
- causing relative motion between the stylet and the cannula to locate the cannula over the sampling region, and
- while removing the stylet from the tissue, delivering a marker from the sampling portion into the tissue.
