Method And System For Powering Implantable Devices |
摘要 |
A ventricular assist device (VAD) system includes one or more external subsystems including an amplifier energizing a drive loop with alternating current, and a Tx resonator inductively coupled to the drive loop. An implanted subsystem includes a VAD, an Rx resonator that forms a magnetically coupled resonator with the Tx resonator, and a load loop for providing power to the VAD that is inductively coupled to the Rx resonator. A sensor monitors the drive loop and a controller uses the sensor data to adjust a system parameter to optimize energy transfer performance. Distributing a plurality of the external subsystems throughout a defined space provides a patient with freedom of movement within the defined space. |

1. A method for powering a medical device implanted in a subject, comprising:
transmitting radio frequency energy from a power source to an external drive loop that is inductively coupled to an external transmitter resonator; and magnetically coupling the external transmitter resonator to an implanted receiver resonator that is coupled to a medical device implanted in a subject, such that power is transferred to the implanted medical device. |
