Abstract
A hand-held aspiration device is provided which has a relatively small suction volume along a suction path to improve responsiveness of the aspiration device when the device is activated. The device may be manually powered and may be provided without electronic controls. The device has a suction path which may be purged into a disposal enclosure to reduce the volume of material under the influence of the suction pressure during the procedure. The suction source may also be part of the hand-held unit to further reduce the suction path and suction volume.
