Wireless Implantable Neurodevice Microsystem
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.
- The number of serious adverse events (SAEs) and adverse events (AEs) reported per patient 12 months post-implantation. [ Time Frame: 12 months post-implant ]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.
- The signal quality of the electrodes for long-term recording of neural signals. [ Time Frame: Day 1 to Day 365 post-implant ]Signal quality will be measured by the number of channels with identifiable single units tracked across each day for 12 months.
- Decoding accuracy per training session. [ Time Frame: Day 1 to Day 365 post-implant ]Decoding accuracy will be measured in percentage (%).
- Number of successful trials per session [ Time Frame: Day 1 to Day 365 post-implant ]The number of successful trials per training session will be measured in percentage (%).
- Time taken to complete each trial per session [ Time Frame: Day 1 to Day 365 post-implant ]This will be measured in seconds (s).
