Zusammenfassung:A method and system for affecting a thrombus after ischemic stroke. The method may include injecting a plurality of magnetic particles into a bloodstream and moving or distorting a thrombus formed or lodged in the bloodstream using a magnetic force to manipulate the magnetic particles. The method may include conjugating ferromagnetic particles, paramagnetic particles, or superparamagnetic particles to a thrombus-specific attachment agent such as an anti-fibrin antibody, and injecting the conjugated particles into the bloodstream. Thereafter, the thrombus may be agitated, broken apart, or dissolved using a magnetic field to exert a magnetic force on the conjugated particles. The method may also include injecting a thrombolytic agent into the bloodstream to interact with and further dissolve the thrombus.
