Intracranial pressure monitoring animal and Codman comparative experimental data

All procedures strictly followed aseptic surgical protocols and animal welfare ethical requirements.Two monitoring probes were sequentially implanted at adjacent sites on the same side within the same surgical area. First, the calibrated Codman invasive ICP monitoring probe (Codman microsensor 826631, Integra Life Sciences Production Corporation) was implanted as the gold standard reference.

Subsequently, the calibrated wireless ICP monitoring probe developed in this study was implanted, ensuring that the sensing elements of both probes were positioned at the predetermined intracranial monitoring level, guaranteeing monitoring position consistency and data comparability.
