Brief Summary

This study aims to evaluate the safety of a wireless implantable neurodevice microsystem in tetraplegic patients, as well as the efficacy of the electrodes for long-term recording of neural activities and the successful control of an external device.

Conditions

Tetraplegia; Tetraplegia/Tetraparesis; Spinal Cord Injuries; Amyotrophic Lateral Sclerosis; Motor Neuron Disease; Locked-in Syndrome; Muscular Dystrophies

Outcome Measures

Primary Outcomes (1)

• The number of serious adverse events (SAEs) and adverse events (AEs) reported per patient 12 months post-implantation.

  The primary objective of this study is to determine the safety of the device. This will be assessed based on the number of SAEs and AEs reported for each patient during the 12 months post-implantation evaluation. This measure will considered a success if the device is not removed for safety reasons within 12-months after implantation.

  6 months post-implant

Secondary Outcomes (4)

• The signal quality of the electrodes for long-term recording of neural signals.

  Day 1 to Day 365 post-implant

• Decoding accuracy per training session.

  Day 1 to Day 365 post-implant

• Number of successful trials per session

  Day 1 to Day 365 post-implant

• Time taken to complete each trial per session

  Day 1 to Day 365 post-implant

Study Arms (1)

EXPERIMENTAL

Wireless Implantable Neurodevice Microsystem

Device: BrainConnexion

Interventions

BrainConnexion DEVICE

A 4.4mm by 4.2mm electrode array is placed onto the surface of the motor cortex which is then connected to a miniaturized neural recording microsystem that transmits signals wirelessly to control an external assistive device. Neural signals are recorded at least once every week for 12 months or longer.

Also known as: Neurodevice, NeuroPort

Eligibility Criteria

• Age: 21 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• years old and older
• Tetraparesis
• Written informed consent obtained from the patient or legal representative (in the event where the patient is unable to provide consent) prior to entry into the study in accordance with local EC/IRB regulations and/or other application regulations for surrogate consent.
• Able to perform the pre-operation Brain Computer Interface training as judged by the research team.

You may not qualify if:

• Significant medical co-morbidities e.g. cardiac disease
• Bleeding disorders
• Any contraindication to surgery
• Other concomitant intracranial pathologies
• History of seizures or epilepsy disorder
• Complications of coagulopathy
• Surgically unfit
• Significant psychological issues e.g. Depression
• Poor psychological support
• Pregnancy
• No means of communication
• Any disease, in the opinion of the Investigator, that is unstable or which could jeopardise the safety of the patient
• If applicable, psychological assessment may be performed prior to selection as the implantation process will be a long a stressful event, requiring a significant degree of patient cooperation and resilience.
