Intended Use
The Embrace is a prescription only device that is indicated for use as an adjunct to seizure monitoring of adults in home or healthcare facilities during periods of rest. The device is worn on the wrist, and senses Electrodermal Activity (EDA) and motion data to detect patterns that may be associated with generalized tonic seizures in patients with epilepsy or at risk of having epilepsy. When a seizure event is detected, Embrace sends a command to a paired wireless device that is programmed to initiate an alert to a designated caregiver. The System records and stores data from Accelerometers, EDA, and Temperature for subsequent review by a trained healthcare professional.
Device Description
The Embrace is a wearable biosensor device that can capture, store, and wirelessly transmit sensor data via Bluetooth to a paired remote device. Embrace runs an on-board algorithm to continuously process sensor data and make a decision about whether the data might indicate a generalized tonic clonic seizure (GTC). The algorithm has been validated on data, labeled using the gold-standard video-Electroencephalogram (EEG) methodology designed by a group of epileptologists at a top level 4 epilepsy center, from epilepsy patients experiencing GTCs in hospital Epilepsy Monitoring Units. When a likely GTC is detected, the Embrace sends a message to the Alert smartphone application, which initiates calls and texts to summon the attention of designated caregivers.
More Information

Unknown
The summary mentions an "on-board algorithm" that processes sensor data and makes decisions, and that this algorithm was "validated on data". While this suggests a data-driven approach, the term "algorithm" is too general to definitively confirm the use of AI/ML. The summary does not explicitly mention AI, ML, or related terms like neural networks or deep learning.

No.

The device is indicated for use as an adjunct to seizure monitoring and detection; it does not directly treat or prevent a disease or condition.

Yes

The device "senses Electrodermal Activity (EDA) and motion data to detect patterns that may be associated with generalized tonic seizures" and "runs an on-board algorithm to continuously process sensor data and make a decision about whether the data might indicate a generalized tonic clonic seizure (GTC)." This indicates it is used to identify a medical condition (seizures), which is the definition of a diagnostic device. While it also initiates an alert, its primary function described is the detection of specific physiological patterns for medical assessment.

No

The device description explicitly states "The Embrace is a wearable biosensor device" and mentions capturing, storing, and transmitting sensor data via Bluetooth. This indicates the presence of hardware components beyond just software.

Based on the provided information, the Embrace device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs analyze samples taken from the human body. The Embrace device is a wearable biosensor that senses physiological data (Electrodermal Activity and motion) directly from the patient's wrist. It does not analyze blood, urine, tissue, or any other sample taken from the body.
  • The intended use is for monitoring and alerting. The device is used to detect patterns associated with seizures and send alerts to caregivers. It is not used to diagnose a condition by analyzing a biological sample.

The Embrace device falls under the category of a medical device that monitors physiological signals. Its function is to detect and alert based on these signals, not to perform a diagnostic test on a biological specimen.

Description of the training set, sample size, data source, and annotation protocol

The algorithm has been validated on data, labeled using the gold-standard video-Electroencephalogram (EEG) methodology designed by a group of epileptologists at a top level 4 epilepsy center, from epilepsy patients experiencing GTCs in hospital Epilepsy Monitoring Units.

Description of the test set, sample size, data source, and annotation protocol

135 patients diagnosed with epilepsy were admitted to the Epilepsy Monitoring Unit (EMU) for standard care were enrolled in the studies: 76 children (39 males), ages 5 months -17 years, median: 10.5 years; 59 adults (23 males), ages: 18-63 years, median: 37 years. 22 EMU patients experienced a total of 40 generalized tonic clonic seizures (GTCSs) while 113 EMU patients didn't experience any seizure. The 40 recorded GTCSs included 10 primarily generalized tonic-clonic seizures and 30 secondarily generalized tonic-clonic seizures. Every recorded seizure was classified as epileptic. Seizures other than GTCSs were discarded from the analysis. 135 patients provided overall 272.1 days (6,530.0 hours), with a median of 34.5 hours of data per patient (min-max range = 3 - 386.8 hours) of ACM and EDA measurements.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Clinical Testing was performed to demonstrate the ability of the Embrace to function as an assessment aid for monitoring for seizure related activity in the intended population and for the intended use setting.
135 patients were enrolled.
Positive percent agreement (PPA) was found to be 1.0 (corrected PPA=0.9334), with a 95% confidence interval of [0.9213, 0.9424], relative to a panel of three readers, and false alarm rate (FAR) was found to be 0.4286 false alarms per 24 hours with a 95% confidence interval of [0.3425, 0.7002], corresponding to a mean FAR (average of FARs across patients) of 0.5894.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

Positive percent agreement (PPA) = 1.0 (corrected PPA=0.9334)
False alarm rate (FAR) = 0.4286 false alarms per 24 hours (mean FAR = 0.5894)

Performance Testing:

Performance testing demonstrates that Embrace complies with IEC 60601-1:2005+AMD1:2012, IEC 60601-1-2:2014, ISO 10993-5:2009, and ISO 10993-10:2010

Clinical Testing:

Clinical testing was performed to demonstrate the ability of the Embrace to function as an assessment aid for monitoring for seizure related activity in the intended population and for the intended use setting.

Patients:

135 patients diagnosed with epilepsy were admitted to the Epilepsy Monitoring Unit (EMU) for standard care were enrolled in the studies: 76 children (39 males), ages 5 months -17 years, median: 10.5 years; 59 adults (23 males), ages: 18-63 years, median: 37 years.

Observed GTCS:

22 EMU patients experienced a total of 40 generalized tonic clonic seizures (GTCSs) while 113 EMU patients didn't experience any seizure. The 40 recorded GTCSs included 10 primarily generalized tonic-clonic seizures and 30 secondarily generalized tonic-clonic seizures. Every recorded seizure was classified as epileptic. Seizures other than GTCSs were discarded from the analysis.

Recorded data:

135 patients provided overall 272.1 days (6,530.0 hours), with a median of 34.5 hours of data per patient (min-max range = 3 - 386.8 hours) of ACM and EDA measurements.

Performance:

Positive percent agreement (PPA) was found to be 1.0 (corrected PPA=0.9334), with a 95% confidence interval of [0.9213, 0.9424], relative to a panel of three readers, and false alarm rate (FAR) was found to be 0.4286 false alarms per 24 hours with a 95% confidence interval of [0.3425, 0.7002], corresponding to a mean FAR (average of FARs across patients) of 0.5894.

Conclusion:

The subject device has the same intended use as the predicate device, and differences in technological characteristics do not raise different questions of safety and effectiveness. On this basis, Embrace is substantially equivalent to the legally marketed predicate device.
