| Submission Type | Traditional |
| Regulation | 21 CFR 882.1620 |
| Device Class | Class 2 |
Indications for Use
The LICOX PMO Brain Oxygen Monitoring System measures intracranial oxygen and temperature and is intended as an adjunct monitor of trends of these parameters, indicating the perfusion status of cerebral tissue local to sensor placement. LICOX 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 are a concern.
Device Story
LICOX PMO Brain Oxygen Monitoring System monitors intracranial oxygen (PbtO2) and temperature; utilizes combined oxygen/temperature sensing probe (CC1.P1) inserted into brain parenchyma via introducer/bolt kit. System consists of disposable probe, PMO Interface Device, and cables. Operates via analog signal transmission; no microprocessor or screen on interface device; powered by battery or bedside monitor excitation voltage. Clinicians use output to track perfusion trends in patients with head trauma or post-craniotomy. Data serves as adjunct to clinical practice to identify potential hypoxia or ischemia; not for sole diagnostic or therapeutic decision-making. Benefits include early detection of secondary neurological insults.
Clinical Evidence
Bench testing only. Biocompatibility testing conducted per FDA G95-1 and ISO 10993. Performance testing confirmed probe design and system safety.
Technological Characteristics
Materials: Polyethylene (tissue-contacting). Sensing: Clark cell (O2), Type K thermocouple (temperature). Form factor: 0.65-1.3 mm diameter probe. Power: Battery or bedside monitor excitation. Connectivity: Analog output to bedside monitor. Sterilization: Sterile, single-use.
Indications for Use
Indicated for patients with head trauma or undergoing craniotomy who are at risk for cerebral hypoxia or ischemia. Used as an adjunct monitor for intracranial oxygen and temperature trends.
Regulatory Classification
Identification
An intracranial pressure monitoring device is a device used for short-term monitoring and recording of intracranial pressures and pressure trends. The device includes the transducer, monitor, and interconnecting hardware.
