III. **Predicate Device:**

Primary Predicate Device:
The HemoSphere Advanced Monitoring Platform (K243781 cleared July 23, 2025) is being utilized as the primary predicate for substantial equivalence to the inherent use and basic device functionality of non-invasive hemodynamic monitoring, the principle of operation of core ClearSight technology, the hemodynamic parameters measured, and compatible finger cuffs. The indications for use relative to non-invasive blood pressure hemodynamic monitoring are also equivalent between the subject device and primary predicate.

IV. Device Description:

Device Description: The HemoSphere Nano Monitor is a hand-held monitoring device that measures the arterial pressure waveform collected from a connected non-invasive finger cuff and displays blood pressure and derived hemodynamic parameters. These parameters are continuously displayed for up to a period of 10 minutes, serving as a series of spot-check or point-in-time measurements. As such, the device does not feature any physiological alarms. It is compatible for use with the single use Acumen IQ Plus finger cuff (AIQCA2; cleared via K243781).

The HemoSphere Nano Monitor utilizes the same principle of operation, algorithms, and mechanism for non-invasive monitoring hemodynamic parameters as the primary predicate, HemoSphere Advanced Monitoring Platform (K243781). When compared to the primary predicate, the subject device introduces a new hardware configuration with a smaller form factor. This new hardware configuration is powered by a rechargeable battery and features a smaller display to enable the product to be handheld. Contrary to the predicate which incorporates a modular approach, the subject integrates all existing non-invasive technology (i.e., the ClearSight Module and Pressure Controller) into the HemoSphere Nano Monitor body itself to provide a unified and compact solution for non-invasive hemodynamic monitoring.

V. Indications for Use:

Indications for Use: The HemoSphere Nano™ Monitor when used with a compatible non-invasive finger cuff is indicated for adult patients (≥ 18 years of age) in whom cardiac function parameters need to be evaluated as part of a patient assessment. The HemoSphere Nano™ Monitor and compatible finger cuffs noninvasively measure blood pressure and associated hemodynamic parameters.

Intended Use: The HemoSphere Nano™ Monitor is intended to be used in a setting where healthcare is administered by qualified personnel or trained clinicians. The HemoSphere Nano™ Monitor is intended for use with compatible non-invasive finger cuff for noninvasive measurement of blood pressure and associated hemodynamic parameters.

VI. Comparison with predicate device(s):

Comparison of indications
The HemoSphere Nano Monitor (subject) and HemoSphere Advanced Monitoring Platform (predicate) have the following similarities:
- Subject and predicate have the same intended use, i.e., non-invasive measurement of blood pressure and associated hemodynamic parameters. No new functionality is being added as a result of this submission.
- Subject and predicate have the same indications as they are intended for use in adult patients (≥ 18 years of age) in whom cardiac function parameters need to be evaluated for patient assessment.
- Both subject and predicate devices are prescription use (Rx) devices that are intended for use by healthcare professionals only.

Comparison of technological characteristics
The ClearSight continuous non-invasive blood pressure monitoring principle based on volume-clamp methodology is the fundamental technological principle for both subject and predicate devices.

At a high-level, the HemoSphere Nano Monitor (subject) and HemoSphere Advanced Monitoring Platform (predicate) have the following similarities:
- Subject and predicate have the same principle of operation and technological characteristics relative to non-invasive blood pressure measurement.
- The subject utilizes the same existing CNIBP Technology (i.e., same volume-clamp principle of operation and cleared algorithms) to measure arterial blood pressure.
- Subject provides the same derived hemodynamic parameters for display as the predicate. No new parameters are being added as a result of this submission. The performance requirements and specifications are equivalent between the subject and predicate device.
- Subject and predicate both use the same accessories i.e., Acumen IQ Plus finger cuffs.

{7}

The HemoSphere Nano Monitor (subject) and HemoSphere Advanced Monitor (predicate) have the following differences:

- The predicate HemoSphere Advanced Monitoring Platform is modular and supports hemodynamic monitoring via invasive, minimally invasive and non-invasive modalities, whereas the subject only utilizes a subset of the overall functionality of the predicate (i.e., non-invasive hemodynamic monitoring).
- The subject has a streamlined GUI for display of CNIBP parameters only (i.e., subset of the GUI features of the predicate).
- The subject has a smaller form factor that integrates the CNIBP machinery (i.e., pump and manifold) into the monitor body to enable the device to be hand-held. This difference in size does not change the overall intended purpose as it does not have an impact on the CNIBP functionality or the associated performance specifications. Testing was performed to show the same performance specifications are met.
- Unlike the predicate which is intended for short-term continuous hemodynamic monitoring with alarms, the real-time data available on the subject is meant for transient use and spot-checking without physiological alarms in healthcare settings. These differences do not change the overall intended purpose as both have the purpose of non-invasive blood pressure monitoring. Additionally, both the subject and predicate devices are prescription use (Rx) devices that are intended for use by healthcare professionals only.
