Abstract
A surgical hand piece is described that maintains a vacuum pressure within the hand piece at a selected level. A check valve is provided substantially near an inlet of an integrated aspirating pump. The check valve opens to introduce fluid into the hand piece to maintain the vacuum pressure within the hand piece at or above the selected level so as to prevent or substantially reduce post-occlusion flow.
