Regulatory Classification

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.

Dear Oliver Buttleman:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

## 4. Device Description

The Viking Fixed Curve Diagnostic Catheters (also referred to as Viking Catheters) are intended for use in electrophysiology procedures to record, stimulate and pace in the diagnosis of cardiac arrhythmias.

The Viking Catheters receive electrical signals from the cardiac tissue, which are transmitted via the electrode wiring through the connector and cable to an amplifier, where the signals are displayed on an EP recording system for the physician to view and interpret in diagnosing cardiac arrhythmias. The physician inserts the diagnostic catheter into the vasculature percutaneously. To reach the right side of the heart, either the internal jugular vein, the subclavian veins, or the femoral veins can be accessed. To reach the left ventricle, the retrograde approach via the femoral artery can be used. In some cases, the radial artery may be used to access the targeted cardiac chamber. Using fluoroscopic guidance, the physician then navigates the diagnostic catheter to the target site using the catheter steering mechanism, as confirmed by the intracardiac electrograms and/or pacing threshold, confirming electrode to endocardium interface.

Viking Catheters are radiopaque, flexible, insulated catheters. The catheters have a polymer shaft that houses the electrical wiring that connects the electrodes to a connector at the proximal end of the catheter; each electrode wire is soldered into this connector. When the catheter is used, the connector is attached to a sterile cable that connects to the hospital recording and pacing equipment.

The Viking Catheters are offered pre-packaged sterile and are a single use product not to be reused, reprocessed, or resterilized. The method of sterilization is ethylene oxide (EO).

## 5. Intended Use & Indications for Use

The Viking Fixed Curve Diagnostic Catheter is intended for temporary intracardiac sensing, recording, stimulation, and temporary pacing during the evaluation of cardiac arrhythmias. The device is intended for use in adult (not pediatric) patients, with the exclusion of pregnant and/or nursing patients.

### Indications for Use

The VIKING Fixed Curve Diagnostic Catheter is indicated for use to diagnose cardiac arrhythmias.

## 6. Comparison of Technological Characteristics with the Predicate Device

technology, manufacturing processes, sterilization process and intended use as those featured in the predicate device. The difference between the subject and predicate devices is minor modifications to certain design requirements and test methods to align with current standards and Boston Scientific’s quality system.

## 7. Performance Data

The proposed labeling modifications of the Viking Catheters do not impact the device's substantial equivalence to the previously cleared version of this device. The device is as safe, as effective, and performs as well as the predicate device. The indications for use, intended use, classification, product functions, materials, configuration, and sterility are substantially equivalent to the predicate device.

The following performance data were provided in support of the substantial equivalence:

## Bioburden Testing

Bioburden testing, per ISO 11737-1, Microbiological Methods – Part 1: Determination of a Population of Microorganisms on Products, was performed to confirm bioburden levels of the devices were not adversely affected.

## Design Verification Testing

Design verification testing was performed on the Viking Catheters to demonstrate that the devices, as manufactured, packaged and 2x EO sterilized, adhere to the requirements set forth in accordance with the applicable product specifications.

Testing was conducted at baseline (T=0) and 25 months (761 days) accelerated aging to support the labeled shelf life.

## Packaging Verification Testing

The Packaging Design Verification testing provides evidence that the catheter packaging configurations meet the predetermined design input specification and maintain sterility in conformance with ISO 11607-1.

## 8. Conclusion

The subject Viking Fixed Curve Diagnostic Catheters are substantially equivalent in indications for use, design, product function, materials, and sterility to the predicate Viking Diagnostic Electrode Catheters. The performance data supports that the subject catheters are substantially equivalent to the predicate device.
