I assume they meant code directly funded (i.e. written by a subsidiary of) the NHS, not proprietary purchases. Seems that's not the case here though, the device is proprietary.
See my comment above. The NHS are implanting devices / software created by an American company, and use the supplied telemetry systems to get medical data. I have no evidence that the data is also sent back to the US company, especially given that the NHS are paying for the bandwidth.
