1. A combination introducer and stylet, the combination comprising: an elongated substantially tubular introducer extending along a longitudinal axis from a proximal end to a sharpened distal end, the introducer including at least one window positioned at a predefined location along the longitudinal axis from a distal tip, the introducer including a lumen adapted to receive a biopsy device and wherein the lumen extends from the proximal end to the distal end of the introducer such that the biopsy device can access tissue through the at least one window, and wherein the introducer includes one or more radio-opaque portions marking an extent of the at least one window; and an elongated stylet extending along a longitudinal axis from a proximal end to a distal end, the stylet being adapted to be received in the lumen of the tubular introducer, wherein the proximal end of the introducer is adapted to releasably engage with the proximal end of the stylet when the stylet is placed in the lumen of the introducer and wherein when the proximal end of the stylet is engaged with the proximal end of the stylet the distal end of the stylet extends into the distal end of the introducer to support and stabilize the introducer during insertion.
