During the first 12 months of the project, BrainProtect advanced from a clinical-grade prototype to a finalised, validated system ready for multicentre clinical investigation, with all technical work packages for this period completed.
During this period, the company's quality management system also achieved ISO 13485 certification, confirming that BrainProtect's development, manufacturing, and clinical preparation activities meet the international quality standard for medical devices.
On the algorithm and software side, the project optimised the core signal-processing and artificial intelligence algorithms underlying cerebral autoregulation and intracranial pressure waveform detection. Multiple AI architectures, feature engineering approaches, and signal-processing techniques were systematically evaluated, leading to improved artifact filtering, more robust signal quality assessment, and refined trend classification. These improvements were consolidated into a final algorithm specification, implementing the system's core autoregulation indices and a closed-loop blood flow modulation and telemetry architecture. Performance validation testing, combining technical verification in laboratory conditions with clinical-environment testing, confirmed that safety, usability,and operational performance requirements were met, and that AI-assisted monitoring performance aligned with clinical expectations.
On the hardware and manufacturing side, the BrainProtect system components, including the Archimedes 02 sensor units, contact modules, and the BrainProtect Plugin, successfully passed all in-process and final quality inspections, with no non-conformances identified. Five complete BrainProtect system sets were assembled, verified, and formally released for deployment to clinical investigation sites, with full traceability established through Device History Records within the company's quality management system.
In parallel, the project completed the documentation required to prepare for clinical investigation: training materials for clinical trial staff covering device setup, signal verification, safety procedures, and incident reporting; and a clinical trial protocol defining patient inclusion and exclusion criteria, safety monitoring, informed consent procedures, and adverse event reporting, developed in line with ISO 14155 and Good Clinical Practice principles, GDPR and relevant medical device data standards.
Underpinning all technical activities, a comprehensive risk management framework was completed in accordance with ISO 14971, through which all risks initially assessed as high were reduced to acceptable residual levels, supporting an overall favourable benefit-risk assessment for the system ahead of clinical investigation.
Together, these achievements mark the transition of BrainProtect from technical development into active clinical evaluation, with the system, documentation, and trained personnel now in place to support the ongoing multicentre clinical investigation.
