Indications for Use

The RAUMEDIC® - PTO-Monitoring-System measures intracranial pressure, temperature and oxygen and is intended as an adjunct monitor of trends in these parameters, indicating the perfusion status of cerebral tissue local to sensor placement. RAUMEDIC® - PTO-Monitoring-System values are relative within an individual, and should not be used as the sole basis for decisions as to diagnosis or therapy. It is intended to provide data additional to that obtained by current clinical practice, in cases where hypoxia or ischemia is a concern. Use of the parenchymal intracranial pressure monitoring kit with bolt is indicated for children who are at least one year old.

Device Story

The RAUMEDIC PTO-Monitoring-System is a multi-parameter intracranial monitoring device used in clinical settings by neurosurgeons. It utilizes implanted catheters (NEUROVENT series) containing piezoresistive pressure sensors for ICP, thermistors for temperature, and luminescence optical fiber sensors for ptiO2. The system includes a user interface unit (EASY logO) that processes signals from the catheters via dedicated cables (PTO and LWL). The EASY logO displays real-time measurements of ICP (including pulsatile ICPA), temperature, and oxygen, and provides technical alarms. Data can be exported to external patient monitoring units via specialized cables. The system provides trend data to assist clinicians in assessing cerebral perfusion status; it is not intended as the sole basis for diagnosis or therapy. Benefits include continuous, localized monitoring of physiological parameters in patients at risk of cerebral hypoxia or ischemia.

Clinical Evidence

Bench testing only. Performance evaluated against ANSI/AAMI NS 28:1988/(R) 2006 for ICP monitoring and ASTM E1112-00 (2006) for temperature. Oxygen sensor performance compared to predicate (K980380) regarding drift, accuracy, and response time. Biocompatibility testing conducted per ISO 10993-1, -5, and -18.

Technological Characteristics

System comprises intracranial catheters (piezoresistive pressure sensor, thermistor, luminescence optical fiber), cranial bolt kits, and EASY logO interface. Materials comply with ISO 10993. Connectivity via dedicated cables to external patient monitors. Sterilization via Ethylene Oxide. ICP sensor: Wheatstone bridge/piezoresistive. Temperature sensor: thermistor. Oxygen sensor: fiber optic quenching.

Indications for Use

Indicated for children (≥1 year) and adults requiring adjunct monitoring of intracranial pressure, temperature, and interstitial fluid oxygen partial pressure (ptiO2) to assess cerebral tissue perfusion status in cases where hypoxia or ischemia is a concern.

Regulatory Classification

Identification

Device Classification Name: Classification Panel: CFR Section: Device Class: Product Code: Device, Monitoring, Intracranial Pressure, Temperature and Oxygen Neurology 21 CFR §882.1620 Class II GWM #### 5. Device Description The RAUMEDIC® -PTO-Monitoring-System determines the level and change in intracranial pressure (ICP) by using semi-conductor pressure sensors, in temperature using thermistors, and in partial oxygen pressure ptiO2 using a luminescence optical sensor fibre. The PTO-Monitoring-System consists of intracranial catheters, a cranial bolt kit, the user interface unit (EASY logO), cables to connect the catheters to the EASY logO and cables for the EASY logO to send the measurements to specific patient monitoring units. Three intracranial catheters are provided: NEUROVENT®-PTO, NEUROVENT® TO and NEUROVENT® PTO 2L. The NEUROVENT®-PTO measures three physiological parameters - ICP, temperature and partial oxygen pressure. The application has to be made with a single lumen Bolt (BOLT-KIT PTO). The NEUROVENT -PTO 2L also measures these three parameters, but has to be placed with a multi lumen Bolt (BOLT KIT PTO 2L) or via tunneling process. The NEUROVENT® TO measures two physiological parameters – temperature and partial oxygen pressure. The application has to be made with a single lumen Bolt (BOLT-KIT PTO). The NEUROVENT®-PTO or the NEUROVENT®-TO is implanted in the parenchyma using a BOLT KIT PTO. The NEUROVENT®-PTO 2L is implanted in the parenchyma using a BOLT KIT PTO 2L or using a RAUMEDIC® spliceable tunnelling sleeve CH8 (already cleared for market under 510(k) K112017). Device #: {2}------------------------------------------------ Image /page/2/Picture/0 description: The image shows the logo for RAUMEDIC. The logo consists of a circular graphic on the left, followed by the word "RAUMEDIC" in bold, sans-serif font. Below the word is the tagline "Lifeline to Health" in a smaller, italicized font, flanked by horizontal lines. For connecting the catheters to the EASY logO two cables – cable PTO and cable LWL - are needed. The cable PTO transfers the electrical signal for ICP and temperature. The cable LWL transfers the optical signal for oxygen pressure. The EASY logO is the user interface that displays the measurements and alerts the user to the status of the intracranial catheters. The EASY logO displays: oxygen partial pressure pO2, intracranial pressure ICP, pulse amplitude ICPA and temperature T. ICP is a pulsatile signal that consists of the ICP average value and a pulsatile ICPA component, which is superimposed over the ICP average value. DATALOGGER cables allows the EASY logO to send the measurements to specific patient monitoring units. #### 6. Indications of Use The RAUMEDIC® - PTO-Monitoring-System measures intracranial pressure, temperature and oxygen and is intended as an adjunct monitor of trends in these parameters, indicating the perfusion status of cerebral tissue local to sensor placement. RAUMEDIC® - PTO-Monitoring-System values are relative within an individual, and should not be used as the sole basis for decisions as to diagnosis or therapy. It is intended to provide data additional to that obtained by current clinical practice, in cases where hypoxia or ischemia is a concern. Use of the parenchymal intracranial pressure monitoring kit with bolt is indicated for children who are at least one year old. #### 7.
