Abstract
A device for treating cells is disclosed. The device includes a plurality of permanent magnets arranged in a side-by-side relationship with the magnetic north pole and the magnetic south pole of each permanent magnet being adjacent the magnetic north pole and magnetic south pole of an adjacent permanent magnet, respectively, the plurality of permanent magnets forming a ring of permanent magnets. The device further includes an electrically conductive wire wound substantially around the ring of permanent magnets, and tubing wrapped around the ring of permanent magnets between windings of the wire. A cooling device introduces a flow of coolant through the tubing so as to substantially cool the device. The device further includes a control circuit, connected to the wire, for selectively generating a coil current for passing through the wire. The current has an AC component and a DC component. The frequency of the AC component is programmable and is set to substantially match a resonant frequency associated with the cells to be treated. The coil current creates an electromagnetic field that interacts with a magnetic field generated by the ring of permanent magnets to generate a complex …
