Abstract:
1. A method for separating a tissue specimen from an intracorporeal site of a patient, comprising a. providing an elongated probe assembly for a biopsy or other tissue cutting device comprising: b. advancing the probe assembly within the patient until the tissue receiving aperture in the wall of the outer cannula is in a desired intracorporeal site within the patient and the tissue penetrating distal tip is distal to the desired intracorporeal site; c. aspirating tissue at the desired intracorporeal site into the outer cannula through the tissue receiving aperture in the wall of the outer cannula; and d. advancing the inner tissue cutting member distally within the outer cannula with the leading outer tissue cutting edge of the inner tissue cutting member engaging the inner tissue cutting edge of the outer cannula so as to sever a tissue specimen from tissue extending through the tissue receiving aperture of the outer cannula while maintaining a vacuum in the outer cannula through the second opening.
