Instead of selectively evaluating whether a jamming device is in the public interest (to, say, protect us from the malicious), the FCC generally blocks all such devices from the market.

FORBES: New Jamming Tech Could Protect Pacemakers from Hack Attacks

The idea is to use probes similar to those used in GAARDIAN, but interconnected in such a way that the position of a jamming device can be determined by triangulation.

ECONOMIST: GPS jamming

It works by jamming all nearby transmissions at the operating frequency of the medical device, except for those signals that were authorized to use the device.
