No
The description focuses on the physical design, electrode array, location sensing technology (magnetic field), and mechanical manipulation of the catheter. There is no mention of AI or ML being used for data analysis, interpretation, or navigation.
No.
The device is indicated for electrophysiological mapping of cardiac structures (recording and stimulation) and providing catheter tip location information. While it aids in diagnosis, it does not directly treat a disease or condition.
Yes
The device is indicated for "electrophysiological mapping of cardiac structures i.e., recording and stimulation." Electrophysiological mapping involves recording electrical signals to diagnose cardiac conditions, thus qualifying it as a diagnostic device. The predicate device "NAVISTAR diagnostic catheter" further supports its diagnostic intended use.
No
The device description clearly details a physical catheter with electrodes, a location sensor, a deflectable tip, and a hand piece, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is for electrophysiological mapping of cardiac structures, which involves recording and stimulating electrical signals within the body. This is an in vivo procedure.
- Device Description: The device is a catheter designed to be inserted into the heart to interact directly with cardiac tissue.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue samples, etc.) outside of the body, which is the defining characteristic of an IVD.
Therefore, the CS REFSTAR Catheter is an in vivo medical device, not an IVD.

Device Description
The Biosense Webster CS REFSTAR Catheter has been designed to be used with the CARTO 3 EP Navigation System (a magnetic field location technology) to facilitate electrophysiological mapping of the heart.
The CS REFSTAR Catheters have a high-torque 7 Fr shaft with a deflectable tip section containing an array of ten platinum/iridium electrodes that can be used for stimulation and recording of cardiac electrical signals. In addition, there is a single eleventh electrode located on the shaft. This Porterfield type electrode is designed to be positioned in the Vena Cava during use where it will perform as a reference unipolar electrode. The catheter has a location sensor embedded in the tip section that transmits location information to the CARTO 3 EP Navigation System. The shaft has a working length of 115 cm.
The CS REFSTAR Catheter tip deflection is controlled by a proximal hand piece that features a thumb operated sliding piston and is offered in two curve types. D and F. The plane of the curved tip can be rotated during use.
The CS REFSTAR Catheter interfaces with standard recording equipment and the CARTO 3 EP Navigation System via interface cables with the appropriate connectors.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The CS REFSTAR Catheter underwent extensive bench (mechanical, electrical and simulated use) testing. The catheter passed all testing in accordance with appropriate test criteria and standards. The catheter was also subjected to animal testing which demonstrated that the catheter was safe for use in the coronary sinus and that it is capable of functioning within the CARTO 3 EP Navigation System.

§ 870.1220 Electrode recording catheter or electrode recording probe.
(a)
Identification. An electrode recording catheter or an electrode recording probe is a device used to detect an intracardiac electrocardiogram, or to detect cardiac output or left-to-right heart shunts. The device may be unipolar or multipolar for electrocardiogram detection, or may be a platinum-tipped catheter which senses the presence of a special indicator for cardiac output or left-to-right heart shunt determinations.(b)
Classification. Class II (performance standards).
