Neurally controlled patient ambulation system

An ambulation system for a patient comprising:

• a biological interface apparatus comprising:
• a sensor adapted to be implanted into a brain of a patient, wherein the sensor comprises a plurality of electrodes for detecting multicellular signals emanating from one or more living cells of the patient, wherein the multicellular signals comprise electrical brain signals;
• a processing unit configured to receive the multicellular signals from the sensor, process the multicellular signals to produce a processed signal, and transmit the processed signal to a controlled device;
• and
• the controlled device configured to receive the processed signal, and an ambulation assist apparatus comprising
• a rigid structure configured to provide support between a portion of the patient's body and a surface, and
• at least a second sensor for detecting data relating to the ambulation assist apparatus
• wherein the data is transferred from the ambulation assist apparatus to the biological interface apparatus.
