From Mind-controlled exoskeleton allows paralysed patient to move again on Dezeen:

Researchers at the Clinatec laboratory in Grenoble have created an exoskeleton, which paralysed users can control with their mind in order to help them move both their arms and legs.

This marks the first time that a prosthetic exoskeleton was successfully used to help a quadriplegic patient move all four of their immobilised limbs.

and

The major innovation behind it is not the exoskeleton itself, but an implant called the Wimagine, designed by microelectronics experts at the CEA research institute, which can record and wirelessly transmit the patient's brain activity.

and

The Wimagines were implanted in his brain in June 2017 and in the 27 months since, he has had to train in order to be able to use the exoskeleton – first by controlling an avatar in a virtual environment and finally by moving the shell itself.

Dezeen has great pictures of both the brain-computer interface and the exoskeleton.
