Magnetically controlled medical devices for interventional medical procedures and methods of making and controlling the same

A method of making magnetically controllable devices for interventional medical procedures comprising the steps of:

• manufacturing a medical device for interventional medical procedures having magnetic materials which are without permanent magnetization, wherein the medical device is one of a wire, guidewire, catheter, radio-frequency wire, micro-catheter, braid, coil, lumen, thrombectomy system, stent, aspiration tool, drug-delivery tool, aneurysm-filling coil, electrical lead, and embolization system;
• and
• establishing permanent magnetization within the magnetic materials subsequent to manufacturing, wherein the permanent magnetization allows the medical device to be magnetically controllable;
• wherein establishing permanent magnetization comprises using a magnet array to magnetize individual segments of the medical device;
• and
• wherein the individual segments have different magnetic orientations, strengths, and magnetization angles.
