Abstract: A magnetically controllable linkage based medical device for interventional medical procedures includes a magnetic tip subassembly including magnet elements thereon; a plurality of linkage body elements connected in sequence, a distal linkage body element coupled to the magnetic tip subassembly, wherein each linkage body element is configured for deflection in at least one deflection direction; a linkage base element coupled to a proximal linkage body element; a support body connected to the linkage base element; at least one pair of control wires passing to the magnetic tip subassembly; wherein the device is configured such that an externally-generated magnetic field deflects the magnetically-controlled linkage-based device in at least one deflection direction, and wherein selectively tensioning the control wires can hold the magnetically-controlled linkage-based device in a desired orientation.

Abstract: A method of making magnetically controllable devices for interventional medical procedures comprises the steps of: Manufacturing a medical device for interventional medical procedures having magnetic materials which are without permanent magnetization; and establishing permanent magnetization within the magnetic materials subsequent to manufacturing, wherein the permanent magnetization allows the medical device to be magnetically controllable. The method may further including the step of packaging and sterilizing the medical device, wherein establishing permanent magnetization occurs after packaging and sterilization. The establishing permanent magnetization within the magnetic materials may include providing different magnetic orientations to distinct portions of the magnetic materials. The magnetic material includes one of a platinum alloy or a palladium alloy.

Abstract: A system and method for therapeutic agent conveyance using configurable magnetic field includes a field generating workstation. The workstation includes at least one, generally a pair of, magnet subassemblies. Each subassembly is rotationally mounted on a rotation axis to orientate the subassembly poles. A rotatable yoke supports each subassembly and the yoke axis is offset from each subassembly rotation axis. Yoke rotation configures a collective system magnetic field.
