摘要： A method for extracting a tissue sample includes altering the pressure inside the lumen of a cannula to facilitate extraction of a tissue sample from the cannula. One aspect of the invention includes a biopsy apparatus comprising a valve for controlling the pressure inside the lumen of the cannula. In one variation, the pressure/vacuum generating device is connected to a cannula with a closed distal end and an orifice located on a circumferential surface of said cannula. A cutting sheath is slidably disposed over said cannula. The valve may be provided between the pressure/vacuum generating device and the cannula to control the pressure within the lumen of the cannula.
