Having worked in the medical industry and other highly regulated industries, I don't believe that there are, nor will there ever be, projects for libre medical equipment.
In regulated industries, the products have to comply with certain norms in order to be allowed to be brought to the market. Those norms exist to ensure the product is as safe as it can be (while still doing its job) and they cover everything from design to manufacturing. Those norms also make it impossible to disclaim liabilities..
If you create a medical device, it has to conform to the relevant norms. And if you claim that your product conforms to those norms, you better prove that it does, because you are liable if it later turns out that your product contains a flaw.
With libre medical devices, there are two parties that could be held liable if an incident occurs: The person who built the device and the person/organization who provided the designs. For both of those, the risk imposed by the liability and being unable to control the other party means that creating libre medical devices is a sure way to bankruptcy.
