1. A system for wirelessly transferring energy to an implanted medical device, the system comprising:
a wireless power transmitting device, the wireless power transmitting device including:
a first transmitting coil having at least one conductor winding, a first radius and a first diameter;a second transmitting coil having at least one conductor winding, a second radius, and a second diameter and arranged to extend along a common axis with the first transmitting coil, wherein the first diameter and the second diameter are substantially equal;a gap arranged between the first transmitting coil and the second transmitting coil and extending along the common axis a distance equal to the first radius of the first transmitting coil;a first plurality of capacitors connected in series along the at least one conductor winding of the first transmitting coil to divide the coil conductor winding into a first plurality of coil segments;a second plurality of capacitors connected in series along the at least one conductor winding of the second transmitting coil to divide the coil conductor winding into a second plurality of coil segments; andan input connection electrically coupled to the first transmitting coil and the second transmitting coil to deliver an excitation voltage to the first transmitting coil and the second transmitting coil substantially equal to a theoretical excitation voltage required to produce a substantially uniform magnetic field between the first transmitting coil and the second transmitting coil divided by a sum of the first plurality of coil segments and the second plurality of coil segments. |
