Abstract
The method of aspirating body tissue and blood from a surgical site along a suction passage having a suction port at an ultrasonically vibrated end of a tool for fragmenting the tissue at the surgical site is improved by introducing an anti-coagulant fluid into the suction passage independently of the suction port.
