Marvel: 10 Most Underused Technologies In The MCU

During the attack on the HYDRA research base in Avengers: Age of Ultron, Hawkeye was critically wounded and the Avengers called in Dr. Helen Cho to use her experimental new technology, the Regeneration Cradle to heal him. The procedure was a total success, completely regenerating Clint's damaged tissue.

This machine is so impressive that it was even able to create an entire body for Vision using vibranium. The possibilities for medical care are limitless! You could easily repair burns and cuts, maybe even regenerate eye tissue and restore sight. It's even possible (though not confirmed) that this device could regenerate lost limbs or other body parts if experimented further.

Though, despite all of this, we never see the Avengers, or anyone for that matter, use this device again after this initial introduction. One would think that with the amount of injuries happening to the Avengers on a regular basis, they would all have a Regeneration Cradle installed in their homes but no, during Hawkeye, despite being saved by this tech in the past, Clint decides to let his wounds heal the old-fashioned way.
