New intracranial pressure monitoring device for home use

Helmbrechts – Medical technology manufacturer Raumedic introduces an intracranial pressure monitoring device for home use – just in time for Medica. Wherever a patient may be – with the help of an implanted telemetric catheter, the handy device called Raumed Home ICP measures pressure inside the cranium – the intracranial pressure, or ICP. The product that has recently received CE marking was developed primarily for people who suffer from hydrocephalus. Hydrocephalus is the buildup of cerebral fluid that increases the size of cavities in the brain. Raumed Home ICP is intended to facilitate the diagnosis of this and similar clinical pictures and to provide indications for therapy. 

Neuromonitoring regardless of location 

The neuromonitoring requires an approximately 20-minute procedure in which the neurosurgeon fully implants a catheter under the patient’s scalp. To register and store the intracranial pressure data, the circular reader antenna of the device is then simply placed above the catheter. Subsequently, the patient is free to move about in his or her home environment. While doing so, the patient can use the control element to select certain activities and events occurring during measurement, such as sleeping, eating, headache, nausea or sports. 

Ingo Bartels, head of the neuromonitoring department at Raumedic, is proud of the innovation: “What used to only be possible at the clinic can now be carried out at home. While patients are taking care of their daily activities, the Raumed Home ICP is continuously monitoring their intracranial pressure.” Scientists believe it is precisely these active phases and specific events that give neurosurgeons better insights for therapy, explains Bartels. 

At the same time, he points out that the values obtained with the Raumedic intracranial pressure monitoring device still have to be reconciled with other established diagnostic methods: “The data taken by self-measurement – together with information from additional treatments – give physicians a sound basis for decisions and for initiating suitable therapeutic measures.”

Market-oriented product development 

Raumedic strongly focused its product development on the needs of the patient and the treating physician. Prior experience from the Raumedic telemetric system already established in the market was helpful, as Ingo Bartels explains: “As we have been active in microchip technology since 1996 and maintain close contact with clinics worldwide, we were able to produce a market-driven design for Raumed Home ICP.”

After about a four-year development period, he believes a product has now been created that combines an easy-to-handle design with simple operation, yet above all delivers realistic measurement data. “Our telemetric catheter measures the absolute parenchymatous pressure. Therefore, it can rule out sources of error and problems from conventional systems, such as extensive flushing of catheters, imprecise zero-point adjustment or artifacts from catheter and patient movement. We are confident that the Raumed Home ICP gives physicians and patients an innovative tool for non-stationary, wireless neuromonitoring.”

Raumedic neuromonitoring solutions 

In close collaboration with research institutions and physicians from major clinical centers, Raumedic has developed microchip catheters and data display devices for multimodal neuromonitoring since 1996. The medical devices are used in neurosurgery for diagnostic and therapy purposes. The devices can measure intracranial pressure (ICP), intracranial temperature (ICT) and oxygen partial pressure (ptiO2), either individually or simultaneously. The medical technology manufacturer also produces catheters used in traumatology that measure intramuscular tissue pressure (IMP). 

Since 2010, Raumedic has distributed the first CE-marked telemetric system for stationary use in clinics. In 2019, the manufacturer expanded its telemetry portfolio to include the Raumed Home ICP, an intracranial pressure monitoring device for home use. At the upcoming Medica, this innovation can be found at booth G42 in hall 11. 

Please note: Raumed Home ICP is not commercially available in all countries, in particular not in the USA. Therefore, this press release is not intended for publication in the USA.

At 230 grams, Raumed Home ICP is lightweight, about as big as a smartphone, and is intended to give hydrocephalus patients a more active life, among other things.

The precision pressure catheter Neurovent-P-tel is fully implanted under the scalp and measures intracranial pressure directly in the parenchyma of the brain.

During measurement, the patient can select and store certain activities or events, such as headaches, with the touch of a button.
