The invention is directed to tissue cutting members and biopsy devices with suchtissue cutting member for separating a tissue specimen from a patient'sbody at a target site. The tissue cutting member is slidably disposed within aninner lumen of an elongated probe member of the biopsy device to cut a tissue specimendrawn into the interior of an outer cannula of the biopsy device through a tissuereceiving aperture in the probe. The tissue cutting member has a tubular distalportion with a distal tip having an outer tissue cutting edge, an inner tissuereceiving aperture, and a longitudinally oriented opening with a closed proximalend and open distal end which opens to the inner tissue receiving aperture to facilitateflaring of the distal tubular portion. The cutting member has at least one openingin a wall of the tubular portion to maintain a vacuum during use.
