Abstract
A biopsy device includes a cannula that defines a tissue chamber configured to receive a tissue sample from a patient. A pressure chamber includes a body having a distal end and a proximal end. The proximal end has an inlet coupled in fluid communication with the cannula. The body has a first recessed area proximate the proximal end, wherein the first recessed area is configured to release positive pressure within the pressure chamber. The body has a second recessed area proximate the distal end, wherein the second recessed area is configured to release negative pressure within the pressure chamber. A piston is movably received in the body and configured to move over the first recessed area to release the positive pressure and configured to move over the second recessed area to release the negative pressure.
