摘要:
A tissue removal device includes a rigid aspiration cannula, a valve communicating with the aspiration cannula in a fluid-sealed manner, and a pneumatically-driven actuator configured for moving the valve between an open position and a closed position, wherein at the open position the valve defines an aspiration path through the aspiration cannula and the valve, and at the closed position the valve prevents vacuum from being applied at the distal tip.
