Hahaha, like the Ventricular Assist Devices.

They bore a one-inch diameter hole in the heart, suture a BLDC impeller motor (VAD) on, then cut into the aorta or whatever, suture fancy material stuff to a tube that then redirects the blood flow through the motor. And a fancy cable that exits your abdomen and connects to the electronics.

It was the single most disturbing thing I’ve ever had the displeasure of working with. I really wish I didn’t know how it worked.
