The System is indicated for those patients who require monitoring for the detection of non-lethal cardiac arrhythmias. The NUVANT System model monitors, derives and displays: • ECG • Heart Rate The System may also monitor, derive and display: • Activity • Posture • Respiration rate (including RR variability) • Body fluid status • Heart rate variability Description of the System The NUVANT System includes: a) PiiX™ - an adherent patient-worn device containing multiple sensors used to track a suite of physiological parameters. The PiiX can also be activated to associate patient symptoms with ECG data using a Patient Trigger Magnet. PiiX can collect approximately 500 ECG episodes. However, PiiX must be replaced after 7.5 days of use or when the end of life indicator appears. An end of life indicator as shown below, will light up when the PiiX needs to be replaced. b) zLink™- a device that receives data from the PiiX and transmits to the Server. c) zLink Charger – a charger for the zLink. d) zLink Holster – a wearable holder for the zLink. e) Prep wipes – wipes used for cleaning the skin prior to applying the PiiX. The NUVANT System enables remote monitoring in ambulatory patients to: a) Detect, store and transmit ECGs and other physiological data. b) Assist physicians/health practitioners in the diagnosis and identification of various clinical conditions/events/trends through web services and patient reports. Based on the indications, the NUVANT System may be used for: a) Patients who require monitoring for known, non-life threatening arrhythmias. b) Patients with symptoms such as chest pain, syncope, lightheadedness or near syncope, vertigo, dizziness, fall, palpitations, transient ischemic episodes, dyspnea (shortness of breath) that might be due to cardiac arrhythmias. c) Patients with cardiac arrhythmia associated with co-morbid conditions. d) Obtaining correlation of rhythm with symptoms when symptoms have unknown etiology. e) Evaluating possible arrhythmias in a) patients recovering from cardiovascular or thoracic surgery; b) survivors of myocardial infarction; c) patients with diagnosed sleep disorder breathing. f) Evaluating benefits after initiating or discontinuation of anti-arrhythmic drug therapy. g) Assessing the results of an ablation procedure for an arrhythmia. Contraindications 1. Patients with known allergies or hypersensitivities to adhesives or hydrogel. 2. Patients with potentially life-threatening arrhythmias, or who require inpatient / hospital monitoring. Precautions 1. PiiX should not be used on patients with implantable devices with active minute ventilation sensors. 2. Patient trigger magnet should not be used in patients who have implanted devices with active magnet features in the vicinity of the PiiX. 3. PiiX should be removed prior to external defibrillation or an MRI scan. 4. PiiX may cause mild discomfort, skin irritation, redness, itching, rash or contact dermatitis in some individuals. The device should be removed if any pain or discomfort occurs. If skin irritation or redness persists after the device has been removed, a topical anti-inflammatory cream may be applied to the area (in consultation with your health care provider). 5. PiiX is intended for single patient use. 6. PiiX should not be applied to broken, damaged or irritated skin.

Replace the PiiX if it peels off; do not reapply the PiiX. 10. Replace the PiiX if it appears damaged. 11. No creams or lotions should be applied immediately prior to use of PiiX. 12. Store PiiX in a cool, dry location. The device is designed to withstand environmental temperature fluctuations between 0° to 40°C. The NUVANT System is not intended to replace direct communication with your healthcare provider. The system data should not be used alone, but should be used along with all other clinical data and exams to come to a diagnosis. The system is not intended to alarm or alert physicians, and will not summon emergency response in the event you need help. Talk to your healthcare provider immediately if you have any concerns, or if your condition changes. Step-by-step Operating Instructions – NUVANT MCT System No specific training is needed for the use of this system. The zLink should be set-up first prior to the PiiX application. zLink Set-up 1. Remove the zLink from the box. 2. Connect the charger connector with the zLink 3. Plug the charger into an electrical outlet. zLink will begin charging immediately. If the lights on the zLink do not display, push the round Power button located below the lights to turn on the zLink. The zLink should be kept connected to the charger until the Power light is blue. zLink Lights Power Light: BLUE ON: Full charge confirmed AMBER ON: Low charge warning AMBER Flashing: Battery capacity less than 10%. Full charge may take up to 4 hours Cell Light: BLUE: Adequate cell coverage AMBER: No cell coverage. Move zLink to another location Other lights on zLink are utilized only if troubleshooting is necessary. Refer to these lights only if asked by a Corventis Customer Service representative. zLink may also be turned ON and OFF manually. To turn zLink ON when zLink is not connected to the charger, press the round Power button located below the lights. All lights will come on, confirming zLink is ON. To turn zLink OFF, press the round Power button for several seconds until all the lights turn off. 4. To initiate use, charge the zLink for a minimum of 4 hours. Keep zLink connected to the charger overnight, every night. With a full charge, the zLink will remain charged for up to 12 hours. Preferably, the zLink should be kept within 30 feet (9 meters) of the patient as much as possible to ensure data transmission.

Use prep wipe provided with PiiX to clean the skin where the device is intended to be applied. Allow the skin to dry. 3. Remove the PiiX from the foil pouch by tearing at the notch and apply immediately. 4. Remove the covers from the underside of the PiiX. 5. Handle the PiiX on the edges until the PiiX is placed on the skin. 6. Place the PiiX in a diagonal position only, oriented with Corventis at the top. Noting the picture below, place the device in the chest region, to the left of the sternum and starting at the clavicle (or collarbone) referred to as the ‘left quadrant’. Avoid moles and pimples. FRONT Note: Apply the PiiX in the position as directed above. The reviewers of the ECG waveform data will not be aware if the user applies PiiX in a location / orientation other than diagonal position in upper left quadrant area of chest. 7. The PiiX must be in direct contact with the skin. Once applied, press the edges firmly against the skin. 8. It is recommended that the PiiX be placed at least ½ inch away from any tight-fitting undergarment to prevent rubbing or chafing. 9. If you experience cardiac symptoms, position the Patient Trigger Magnet just on the surface of the PiiX and move it along the entire length of the PiiX. This will initiate storage of an ECG for subsequent transmission. Look for these indicators to appear on the PiiX display: ECG storage and transmission: Position the Patient Trigger Magnet just on the surface of the PiiX and move it along the entire length of the PiiX. An ECG will be stored and transmitted and subsequently displayed at the secure Corventis website where your physician can review it. PiiX Removal 1. Peel back the edge of the PiiX. Slowly and gently push the skin away from the PiiX as it is removed. Rapid removal can cause skin irritation. 2. If the PiiX does not peel easily, soak the device with water to assist in softening the adhesive. 3. If skin irritation persists, leave the area exposed or under light clothing. Consult your healthcare provider for any topical treatment options. Light behind the filled circle symbol indicates the PiiX is successfully activated. This light will appear when skin contact is made and may blink. Lights behind the circle with crossed line symbol indicate it is necessary to remove your PiiX and replace it with a new PiiX (unless your prescription has ended).

The RR intervals are then used to calculate beat-to-beat heart rate values, which are then aggregated into 5-minute and 24-hour averages for display. The pause algorithm monitors the time between successive R-wave peaks. A timer is reset upon each R-wave peak detection, and a pause trigger is activated if the timer advances to 3 seconds without an R-wave detection. The arrhythmia detection algorithm of the NUVANT MCT System was tested according to ANSI/AAMI EC57 (Testing and reporting performance results of cardiac rhythm and ST segment measurement algorithms) for ventricular tachycardia and ventricular fibrillation and determined to have an average sensitivity of 96.9% and an average positive predictive value (PPV) of 85.3%.
