The B4C System is intended for the monitoring of variation in intracranial pressure in patients with suspected alteration of intracranial pressure (ICP) or change in intracranial compliance, by providing surrogate ICP waveforms and associated parameters (estimated P2/P1 ratio, normalized Time-to-Peak, derived useful ICP pulses and cardiac pulses) for interpretation.

The B4C System is a non-invasive device intended for the monitoring of variation in intracranial pressure, including patients with suspected alteration of intracranial pressure (ICP) or change in intracranial compliance. It consists of a sensor with Bluetooth wireless module, headband, mobile device software application, receiver, external battery pack and charger, as well as processing and analytical software. The sensor contains four strain gauges situated on a metal bar that detects variations in skull deformation through tension and compression of the metal bar in response to changes in intracranial pressure. These resistance measures are converted to a digital signal using a high-resolution ADC (Analog to Digital Converter) in the sensor that is transmitted to software components for viewing, processing and analysis. The proposed device does not measure absolute intracranial pressure values, but produces surrogate waveform morphology, its trend, and associated parameters reflecting changes in ICP. The B4C System and surrogate waveform and associated outputs do not substitute ICP monitoring methods when measurement of the absolute value of ICP is required to make a clinical decision.

The BcSs-PICNI-2000 Sensor is intended for the monitoring of variation in intracranial pressure in patients with suspected alteration of intracranial pressure (ICP) or change in brain compliance, by providing ICP waveforms for interpretation.

The BcSs-PICNI-2000 Sensor ("the Braincare Sensor") is a non-invasive device intended for the monitoring of variation in intracranial pressure, including patients with suspected alteration of intracranial pressure (ICP) or change in brain compliance. It consists of a sensor, headband, and adapter cable. The sensor contains four strain gauges situated on a metal bar that detects variations in skull deformation through tension and compression of the metal bar in response to changes in intracranial pressure. The proposed device does not measure absolute intracranial pressure values, but produces waveform morphology and its trend reflecting changes in ICP. The BcSs-PICNI-2000 Sensor and waveform output do not substitute ICP monitoring methods when measurement of the absolute value of ICP is required to make a clinical decision. The sensor component is supported on a plastic headband worn by the patient, such that the sensor is in contact with the scalp and is perpendicularly positioned in the temporoparietal transition, 2 inches (5-6 cm) above the entrance of the external auditory canal on the coronal plane. Slight pressure is applied so that the sensor pin maintains contact with the scalp throughout the monitoring session. The sensor continuously records and transfers acquired signals through an adapter cable to a compatible multi-parameter monitor that has piezoresistive pressure transducer sensitivities of 5uV/Vex/mmHg or greater and automatic amplitude window adjustment capability. The multi-parameter monitor's inherent software interprets the signal received from the BcSs-PICNI-2000 Sensor and displays a waveform that allows for assessment of suspected intracranial hypertension or changes in brain compliance based on the characteristic Percussion (P1), Tidal (P2), and Dicrotic (P3) peaks of the ICP waveform morphology. The BcSs-PICNI-2000 Sensor is not intended to be a standalone diagnostic tool. The waveform output does not replace a comprehensive clinical evaluation, but only provides an element for preliminary assessment. The clinician is responsible for determining the additional clinical information that may be required to make a diagnosis.
