Claim Text:
1. A biopsy system, comprising: a support structure; an elongate cannula coupled to and extending from the support structure, the cannula having a distal portion with a tissue receiving aperture in a side wall thereof; an elongate hollow introducer sized and configured to be mounted to the support structure over the cannula, wherein the support structure and a proximal portion of the introducer are respectively configured for providing releasable attachment of the introducer to the support structure over the cannula in a first attachment configuration, in which the distal portion of the cannula extends out an open distal end of the introducer with the tissue receiving aperture unobscured by the introducer, and in a second attachment configuration, in which the distal portion of the cannula extends out the open distal end of the introducer with the tissue receiving aperture partially obscured by the introducer; and an axially oscillating cutter disposed in an axial lumen of the cannula, wherein an oscillation stroke length of the cutter when the introducer is attached to the support structure in the first attachment configuration is greater than an oscillation stroke length of the cutter when the introducer is attached to the support structure in the second attachment configuration.
