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.Type: GrantFiled: March 12, 2009Date of Patent: October 23, 2012Assignee: Palo Alto Research Center IncorporatedInventors: David Eric Schwartz, Scott A. Elrod, Richard H. Bruce, Daniel L. Larner
