Abstract
A biopsy assembly includes a biopsy device, a vacuum source, and a valve assembly. The biopsy device includes a body, a needle extending distally from the body, and a cutter translatable relative to the needle. The needle includes a lateral tissue receiving aperture. The cutter is translatable to selectively close the lateral tissue receiving aperture of the needle. The valve assembly is in fluid communication with the needle. The valve assembly includes a first valve, a second valve, and tubular member. Each of the first valve and the second valve selectively provide atmospheric venting or vacuum to the needle. The tubular member is coupled with the vacuum source and includes a first and second connector extending transversely from the tubular member. The first and second connectors couple to the first and second valves to provide vacuum to the first and second valves.
