Miethke M.scio intracranial pressure monitoring device

M.scio is an intracranial pressure (ICP) monitoring device designed for long-term implantation. It is designed to provide an option for managing hydrocephalus, a chronic, neurological condition where CSF accumulates and builds up in the brain and can affect people of all ages, from newborns to older Australians. The M.scio is a coin-sized device implanted along the shunt tubing at the burr hole site. A compressible silicone membrane responds to changes in CSF pressure, which is detected by a measuring cell and transmitted telemetrically to a hand-held receiver for real-time ICP monitoring.

Primarily used in patients with complex hydrocephalus, M.scio is intended to support management of shunt-related complications, CSF disturbances and ICP control. It is designed to enable precise, non-invasive monitoring without zeroing or complex set-ups, and with a 44 Hz sampling rate that provides detailed pressure curves and clinically relevant ICP morphologies for both acute and long-term care. Readings remain stable with minimal drift (<2 mmHg) for up to four years, ensuring consistent accuracy.

Two variants of M.scio are now available in Australia: M.scio Flat (provided with or without catheter) is intended for use in the treatment of patients with hydrocephalus (including subarachnoid haemorrhage induced hydrocephalus) by measuring intracranial pressure; and M.scio Dome (provided with or without catheter) is intended for use in the treatment of patients with hydrocephalus (including subarachnoid haemorrhage induced hydrocephalus) by measuring intracranial pressure, enabling hypodermic infusion or injection of therapeutic substances, and facilitating cerebrospinal fluid drainage.
