The problem is that he wants real-time access to raw data from the device. The manufacturer records data about his heart and proprietary data about how the device is functioning. Very interesting dilema from a software development standpoint. The manufacturer needs to develop a solution for patients, but that will increase production costs.
Having worked med devices the last 12 years I can definitively state that it will cost a minor amount of investment to provide a limited access hook to allow his data without the proprietary device info as both are currently already hooked. Say one engineer for 2 weeks at most (and he/she would spend most time on other projects anyway).
Production cost would not be impacted since it would be a matter of the firmware version being uploaded being swapped out.
Bigger issue would be for those already implanted where firmware can’t be “swapped”. In that case they fall back on - sorry real time access isn’t currently available, but here is the access for your data once it has been downloaded and interpreted. Doctor’s notes aren’t required to be provided with a patients records as I understand so the mfgrs info would not be covered either and can be removed, and patient records aren’t required to be provided real time - only ‘within a reasonably alloted time’. So.... While he has a right to the data he doesn’t have a right to real time data if it wasn’t a feature originally in the device. He doesn’t get MRI pics, blood results, or othe r such items same day so,,,
just wait until people find out how much their DNA is being used without compensation to the DNA owner.
