Abstract:
1. A method for collecting and washing one or more tissue specimens from a target site within a patient, comprising: a. providing a biopsy device having: b. advancing the probe component at least partially into or adjacent to tissue at the target site; c. rotating the tubular section about its longitudinal axis to provide a desired aperture orientation; d. drawing tissue at the tissue site through the aperture of the tubular section into the interior thereof; e. advancing the tissue cutting member longitudinally within the tubular section to cut a tissue specimen from the tissue extending into the tubular section; f. transporting a cut tissue specimen through the inner lumen of the tissue cutting member and discharging the cut tissue specimen from the proximal end of the tissue cutting member; g. collecting the transported cut tissue specimen on the tissue retaining member within the interior of the tissue collector; h. applying fluid to the collected cut tissue specimen through the discharge port in the separate fluid delivery conduit to wash blood or debris from the collected cut tissue specimen while retaining the collected cut tissue specimen on the tissue retaining member; i. applying a vacuum from the vacuum port to withdraw fluid or debris within the inner chamber through the wall with openings of the tissue retaining member while retaining the collected cut tissue on the tissue retaining member within the interior chamber of the tissue collector; and j. removing the tissue retaining member with the one or more retained tissue specimens from the tissue collector.
