Patent ID: 8550089

Claim:
A method of delivering therapeutic agent to a target location in a body comprising: positioning an angioplasty catheter at an obstruction in a coronary artery for performing an angioplasty procedure, the angioplasty catheter having a perfusion lumen; conducting the angioplasty procedure at the obstruction in the coronary artery; infusing a plurality of magnetic particles through the perfusion lumen of the angioplasty catheter into the coronary artery upstream from the target location, each magnetic particle carrying a therapeutic agent, wherein the infusing step is performed simultaneously or nearly simultaneously with the angioplasty procedure; placing a magnetic device in a position to attract the magnetic particles to the target location, the target location being an area of ischemic myocardium; and allowing the magnetic particles to infuse the target location by the attraction of the magnetic particles to the magnetic device.
