Partial or total occlusions of fluid passages within the human body are removed by positioning an array of optical fibers in the passage and directing treatment radiation pulses along the fibers, one at a time, to generate a shock wave and hydrodynamic flows that strike and emulsify the occlusions. A preferred application is the removal of blood clots (thrombi and emboli) from small cerebral vessels to reverse the effects of an ischemic stroke. The operating parameters and techniques are chosen to minimize the amount of heating of the fragile cerebral vessel walls occurring during this photoacoustic treatment. One such technique is the optical monitoring of the existence of hydrodynamic flow generating vapor bubbles when they are expected to occur and stopping the heat generating pulses propagated along an optical fiber that is not generating such bubbles.

A method of controlling an engine having an intake manifold and an exhaust manifold, wherein an exhaust gas recirculation path having a valve is provided between the intake and exhaust manifolds, and the engine has a turbocharger ; the method comprising increasing the opening of the exhaust gas recirculation valve when there is at least one condition of reduced engine output; and adjusting exhaust gas expansion through the turbocharger turbine to reduce expansion through the turbocharger. Reducing turbocharger expansion will reduce the power input to the compressor and slow down the compressor. At the same time, the pressure differential between the intake and exhaust manifolds increases due to the reduced pressure on the exhaust manifold side (because of the reduced expansion). Therefore, more airflow from the intake side can flow into the exhaust side for efficient exhaust to the intake manifold. As a result, the pressure at the outlet of the compressor is further reduced. Thus, such manipulation can reduce the likelihood of surge through the synergistic effect of the two actions.
