Implantable cardiac therapy device with dual chamber can to isolate high-frequency circuitry

摘要

An implantable cardiac therapy device is constructed with a housing that defines first and second chambers. The first chamber holds cardiac therapy circuitry, such as sensing and/or stimulation circuitry The second chamber holds high-frequency circuitry that transmits and receives high-frequency signals used in communication with external devices. The dual-chamber housing allows the implantable cardiac therapy device to handle high-frequency signals in an isolated environment, thereby enabling longer range telemetry, without interfering with the cardiac therapy circuitry. The implantable cardiac therapy device can be linked to a cardiac network of knowledge workers that evaluate the data generated by the device and provide instructions to remotely program the device.
