Intended Use
The intended use of Nautilus DeltaTM is to support navigation and tip positioning of central venous access devices. Nautilus DeltaTM can be used as an alternative method to fluoroscopy and chest X-ray for central venous catheter tip placement confirmation.
Device Story
Nautilus Delta system facilitates real-time central venous access device (CVAD) tip positioning. System inputs: patient cardiac electrical activity (ECG) via sterile extension cable connected to catheter stylet/guidewire. Patient module acquires/processes ECG data; transmits wirelessly (Bluetooth) to mobile medical application. Application displays surface ECG, R-peak markers, heart rate, and navigation signal to guide catheter from access point to cavo-atrial junction (CAJ). Used in clinical settings by healthcare providers; replaces/augments traditional fluoroscopy or chest X-ray. Provides visual feedback on graphical user interface; assists clinicians in accurate tip placement; reduces radiation exposure by minimizing need for imaging.
Clinical Evidence
Clinical data from European post-market use in hundreds of patients across multiple hospitals. No adverse events reported. Side-by-side clinical comparisons with predicate devices demonstrated substantial equivalence. Bench testing confirmed compliance with standards including ES60601-1, IEC 60601-1-2, IEC 60601-2-27, IEC 62304, IEC 62366, ISO 11737-1, ISO 11135-1, ISO 11135-2, EN 55022, and EN 300328.
Technological Characteristics
System includes sterile ECG extension cable, non-sterile ECG cable, patient module, and mobile application. Uses Bluetooth for wireless data transmission. Features include real-time ECG acquisition, R-peak detection, heart rate calculation, and navigation signal computation. Complies with IEC 60601-1 (safety), IEC 60601-1-2 (EMC), IEC 60601-2-27 (ECG monitoring), IEC 62304 (software), and ISO 11135 (sterilization).
Indications for Use
Indicated for navigation/positioning of CVADs (≥3 Fr) using cardiac electrical activity as alternative to X-ray/fluoroscopy. Population: Adults/adolescents (>12-21y) with PICCs, CVCs, ports, hemodialysis catheters; children (>2-12y) with PICCs/CICCs; infants (>1mo-2y) and neonates (birth-1mo) with CICCs. Contraindicated/limited in patients with altered cardiac rhythm (atrial fibrillation, flutter, severe tachycardia, pacemaker-driven rhythm); additional confirmation method required for these patients.
Regulatory Classification

## Indications for Use
510(k) Number (if known) K141634
Device Name Nautilus Delta
#### Indications for Use (Describe)
Nautilus Delta is indicated for navigation and positioning of central venous access devices (CVADs) of at least 3 Fr in size. Nautilus Delta provides real-time catheter tip location by using the patient's cardiac electrical activity and is indicated for use as an alternative method to chest X-ray and fluoroscopy for CVAD tip placement confirmation. In adult patients and in adolescents (greater than 12 through 21 years of age), Nautilus Delta can be used with CVADs such as peripherally inserted central catheters (PICCs), central venous catheters (CVCs), implantable ports, and hemodialysis catheters; in children (greater than 2 to 12 years of age), Nautilus Delta can be used with centrally inserted central catheters (CICCs); in infants (greater than 1 month to 2 years of age) and in neonates (from birth to 1 month of age), Nautilus Delta can be used with CICCs. In each specific age group, the CVAD type and size must be chosen and the CVAD must be used according to the CVAD's indications for use. Limiting but not contraindicated situations for this method are in patients where alterations of cardiac rhythm change the presentation of the P wave as in atrial fibrillation, atrial flutter, severe tachycardia, and pacemaker driven rhythm. In such patients, who are easily identifiable prior to central venous catheter insertion, the use of an additional method is required to confirm catheter tip location.

| Classification Panel: | General Hospital |
| Predicate devices: | Epidural Catheter Connector (K973371)<br>Sherlock 3CG Tip Confirmation System (K113808) |
| Device Description: | The Nautilus Delta™ system consists of the following elements:<br>single use sterile ECG extension cable (also known as Nautilus<br>Electrical Adaptor also known as NautilusE), non-sterile ECG<br>cable, patient module (ECG data acquisition and processing and<br>integrated remote control), and mobile medical application<br>running on any mobile platform which complies with the minimum<br>requirements. Nautilus Delta™ provides real-time catheter tip<br>location information by using the patient's cardiac electrical<br>activity (ECG). This information can be used to position any<br>central venous access devices (CVADs) at or around the cavo-<br>atrial junction (CAJ). Nautilus Delta supports navigation of central<br>venous catheters from the vascular access point towards the CAJ<br>by computing and displaying a navigation signal. Nautilus Delta<br>also displays on its graphical user interface the surface (skin) ECG<br>signal, a marker identifying the R-peak, and the patient's heart<br>rate. In order to obtain intravascular ECG information at the tip<br>(distal end) of a catheter, a stylet or a guidewire inserted in the<br>catheter can be connected to Nautilus Delta patient module via the<br>sterile Nautilus Delta ECG extension cable. Nautilus Delta and<br>NautilusE do not have any direct or indirect contact with the<br>patient. |
| Intended Use: | The intended use of Nautilus DeltaTM is to support navigation and<br>tip positioning of central venous access devices. Nautilus DeltaTM<br>can be used as an alternative method to fluoroscopy and chest X-<br>ray for central venous catheter tip placement confirmation. |

| Summary of Technological<br>Characteristics compared<br>to Predicate Devices: | Nautilus Delta has features, materials and technological<br>characteristics which are similar to the ones of the predicate<br>devices. The most notable differences are:<br>a) Nautilus Delta uses wireless technology (Bluetooth) instead of<br>an USB cable for the ECG data transmission between the<br>Patient and the Operator modules.<br>b) Nautilus Delta uses a mobile platform instead of a netbook PC.<br>c) Nautilus Delta provides a Bluetooth remote control integrated<br>in the Patient Module instead of a standalone Bluetooth remote<br>control.<br>d) Nautilus Delta provides an additional optional navigation<br>signal to support catheter tip navigation from the vascular<br>access point towards the cavo-atrial junction.<br>e) Nautilus Delta displays the patient's heart rate and markers to<br>identify the R-peak of the QRS complex of the ECG<br>waveform. |

Summary of Romedex has performed extensive testing in order to demonstrate Performance Testing: that the new characteristics do not affect safety and effectiveness when compared to the predicate devices and to demonstrate compliance with the following standards: ES60601-1, IEC 60601-1-2, IEC 60601-2-27, IEC 62304, IEC 62366, ISO 11737-1, ISO 11135-1, ISO 11135-2, EN 55022, and EN 300328. Summary of Since obtaining the CE mark, Nautilus Delta also known as Handy Nautilus was successfully used in Europe in hundreds of patients in Clinical Data: several hospitals in several countries by many different users of different backgrounds and experience levels. No adverse events were reported. Side-by-side comparisons with legally marketed similar devices, including the predicate devices, were performed in clinical settings to demonstrated substantial equivalence of Nautilus Delta with the predicate devices. Summary of Based on the analysis of the indications for use, intended use, Substantial Equivalence: technological characteristics, performance tests, and post-market clinical experience, Romedex International has concluded that the new characteristics of the subject device do not affect the safety or effectiveness of the subject device as compared to the predicate devices. Romedex International considers that the new device Nautilus Delta is substantially equivalent to the predicate devices K973371 and K113808.
