The summary describes the device as using the patient's cardiac electrical activity (ECG) to determine catheter tip location and compute a navigation signal. There is no mention of AI, ML, or any complex learning algorithms being used for this processing. The description focuses on standard ECG data acquisition and processing.
No.
This device is designed for navigation and positioning of central venous access devices (CVADs), providing real-time catheter tip location. It functions as a diagnostic and positioning aid, not a therapeutic intervention itself.
Yes
This device is used to confirm the tip placement of central venous access devices, and this confirmation is a form of diagnosis, as it determines the location of the catheter.
No
The device description explicitly states that the system consists of hardware components including a single-use sterile ECG extension cable, a non-sterile ECG cable, and a patient module, in addition to the mobile medical application.
Based on the provided information, the Nautilus Delta device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the body (like blood, urine, tissue) to provide information about a patient's health. The Nautilus Delta system works by using the patient's cardiac electrical activity (ECG) to guide the placement of a catheter within the body.
- The device description explicitly states: "Nautilus Delta and NautilusE do not have any direct or indirect contact with the patient." While the ECG extension cable connects to a stylet or guidewire inserted in the catheter, the device itself is not analyzing a biological sample.
- The intended use is for navigation and positioning of medical devices within the body. This is a procedural guidance tool, not a diagnostic test performed on a sample.
Therefore, the Nautilus Delta is a medical device used for guiding a procedure, not an IVD.

Intended Use / Indications for 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.
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 information 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 PICCs and 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 and instructions 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.

Device Description
The Nautilus Delta™ system consists of the following elements: single use sterile ECG extension cable (also known as Nautilus Electrical Adaptor also known as NautilusE), non-sterile ECG cable, patient module (ECG data acquisition and processing and integrated remote control), and mobile medical application running on any mobile platform which complies with the minimum requirements. Nautilus Delta™ provides real-time catheter tip location information by using the patient's cardiac electrical activity (ECG). This information can be used to position any central venous access devices (CVADs) at or around the cavo-atrial junction (CAJ). Nautilus Delta supports navigation of central venous catheters from the vascular access point towards the CAJ by computing and displaying a navigation signal. Nautilus Delta also displays on its graphical user interface the surface (skin) ECG signal, a marker identifying the R-peak, and the patient's heart rate. In order to obtain intravascular ECG information at the tip (distal end) of a catheter, a stylet or a guidewire inserted in the catheter can be connected to Nautilus Delta patient module via the sterile Nautilus Delta ECG extension cable. Nautilus Delta and NautilusE do not have any direct or indirect contact with the patient.

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.
