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.

Macrophages sequester and aggregate ultrasmall superparamagnetic iron oxide nanoparticles (USPIO) in their lysosomes. The amount of USPIO loading of macrophages depends upon the route and dose of administration, and the pharmacokinetics of accumulation and removal. Both fixed macrophages and activated macrophages associated with inflammatory diseases and cancer phagocytize USPIOs, and the loaded macrophages can serve to identify the extent of a macrophage-dependent disease as well as to direct treatment options. Furthermore, the absorption of energy from incident electromagnetic waves by the aggregated nanoparticles can be used for conformal thermotherapy. The USPIOs can further be used to carry drugs to the same activated macrophages. The co-administered drugs can be bound to the USPIO by condition-dependent releasing links that are responsive to local pH or heating.
