Abstract
A biopsy apparatus includes a cannula, a cutting sheath, and a pressure generating device. The cannula has a lumen, a proximal portion, a closed distal end, and an orifice located on a circumferential surface of the cannula. The orifice is configured to receive a tissue sample into the lumen of the cannula. The cutting sheath is coaxially disposed with the cannula. The cutting sheath is configured to be movable relative to the cannula to selectively cover the orifice. The pressure generating device is coupled to the proximal portion of the cannula. A bifurcated valve assembly is interposed between the cannula and the pressure generating device. The bifurcated valve assembly has a first valve configured to release pressure into the lumen of the cannula and has a second valve configured to facilitate an inflow of air into the pressure chamber of the pressure generating device.
