ALIGNMENT OF EXTERNAL DEVICE RELATIVE TO IMPLANTED DEVICE
The alignment, and positioning of an external device (116) relative to an internal device (128) are indicated on a display (110), and/or by an acoustical signal. In the disclosed application, the external device (116) trans-cutaneously transmits electromagnetic energy to an internal receiver (128) t...

| description | The alignment, and positioning of an external device (116) relative to an internal device (128) are indicated on a display (110), and/or by an acoustical signal. In the disclosed application, the external device (116) trans-cutaneously transmits electromagnetic energy to an internal receiver (128) to provide electrical power for an implanted medical device (128). To ensure optimal coupling between the external transmitter (116) and the internal receiver (128), two permanent magnets (125, 126) are disposed at spaced apart positions on the internal receiver (128). The magnetic field strength of the permanent magnets (125, 126) is sensed by a pair of correspondingly spaced apart Hall effect sensors (120, 121) on the external transmitter (116). As the external transmitter (116) is moved about over the internal receiver (128), the signals produced by the Hall effect sensors (120, 121) drive a display (110) of light emitting diodes (LEDs) (112) that indicates when the maximum magnetic field strength is achieved, i.e., when the Hall effect sensors (120, 121) on the external transmitter (116) are each positioned directly opposite the corresponding permanent magnets (125, 126) on the internal receiver (128). |
