DEVICES AND METHODS FOR DETECTION OF SLIPPAGE OF MAGNETIC COUPLING IN IMPLANTABLE MEDICAL DEVICES |
| 摘要 |
A device for the detection of slippage of magnetic coupling between an implanted medical device having a magnet and an externally applied magnetic field includes at least one external magnet configured to apply the externally applied magnetic field, an induction coil disposed external to the subject and between the at least one external magnet and the implanted medical device, and a detection circuit operatively coupled to the induction coil and configured to detect slippage between the rotational orientation of the magnet of the implanted device and the externally applied magnetic field based at least in part on the varying frequency components of the voltage waveform across the induction coil. |

1. A device for the detection of slippage of magnetic coupling between an implanted medical device having a magnet and an externally applied magnetic field comprising:
at least one external magnet configured to apply the externally applied magnetic field; an induction coil disposed external to the subject and between the at least one external magnet and the implanted medical device; and a detection circuit operatively coupled to the induction coil and configured to detect slippage between the rotational orientation of the magnet of the implanted device and the externally applied magnetic field based at least in part on the varying frequency components of the voltage waveform across the induction coil. |
