NON-INVASIVE MONITORING OF INTRACRANIAL PRESSURE USING TRANSCRANIAL DOPPLER ULTRASONOGRAPHY
Intracranial pressure (ICP) is an important monitoring modality in the clinical management of several neurological diseases carrying the risk of fatal intracranial hypertension. However, this parameter is not always considered due to its invasive assessment. In this scenario, a non-invasive …

Market application of a novel stent-based patency monitor to the management of ischemic vascular disease
… and continuing vascular deterioration. A phenomenon called stent restenosis post procedure exists which puts patients at a relatively high risk for vessel stenosis and occlusion. Stent restenosis may eventually lead to clinical symptoms such as myocardial infarction, stroke or limb loss, and if …

Non-invasive Optoacoustic Monitoring of Neonatal Cerebral Venous Oxygen Saturation
… to diagnose cerebral hypoxia prior to treatment. Invasive internal jugular (IJ) catheters can provide an assessment of cerebral hypoxia with poor clinical outcomes seen once saturation is below 50%, but this method of assessment is not practical for routine screening use in a neonate due to risks …
