Abstract:
1. A method for obtaining a tissue sample with a biopsy device, wherein the biopsy device comprises a probe portion, wherein the probe portion comprises a cannula and a cutter, wherein the cannula comprises a first lumen, a second lumen, and a lateral tissue receiving feature in communication with the first lumen, wherein the cutter is moveable within the first lumen, wherein the method comprises the steps of: (a) actuating the cutter to a first proximal position within the first lumen of the cannula such that at least a portion of the lateral tissue receiving feature is blocked by the cutter, to thereby provide a partially blocked lateral tissue receiving feature; (b) applying a vacuum to the second lumen to prolapse tissue through the lateral tissue receiving feature after the at least a portion of the lateral tissue receiving feature is blocked; and (c) actuating the cutter from the first proximal position to a distal position within the first lumen of the cannula to sever the prolapsed tissue within the partially blocked lateral tissue receiving feature.
