Intended Use
The Wattson™ temporary pacing guidewire is intended to introduce and position catheters and other interventional devices within the chambers of the heart, including those used within transcatheter aortic valve replacement (TAVR) procedures and balloon aortic valvuloplasty (BAV), while transmitting an electrical signal from an external pulse generator to the heart. The temporary pacing guidewire is not intended to remain in place following the clinical procedure.
Device Description
The Wattson temporary pacing guidewire is a dual-purpose 0.035" guidewire designed for the delivery of devices and for temporary rapid pacing of the heart. The distal end of the device has an atraumatic pigtail shape. The shaft of the device has a silicone lubricant applied to the outer surface. Rapid pacing is achieved through a bipolar electrode configuration integrated in the shaft of the guidewire. The electrodes terminate in a single positive electrode at the distal tip of the device and three discrete negative electrodes located proximal to the tip within the pigtail section. The entire device is visible using standard fluoroscopic methods. The device is packaged with a proprietary adapter that locks on to the proximal end of the guidewire and converts it to discrete positive and negative terminal pins. The terminal pins of the adapter are compatible with standard external pulse generators. The Wattson temporary pacing guidewire is sterilized with ethylene oxide.
More Information

Not Found

No
The description focuses on the mechanical and electrical properties of a guidewire for pacing and device delivery. There is no mention of data processing, algorithms, or learning capabilities.

Yes
The device is described as a "temporary pacing guidewire" that transmits an "electrical signal from an external pulse generator to the heart," directly indicating a therapeutic function of delivering electrical therapy.

No

The device is designed to introduce and position catheters and other interventional devices within the heart and transmit an electrical signal for temporary rapid pacing, not to identify or monitor a disease state.

No

The device description clearly outlines a physical guidewire with integrated electrodes, a silicone lubricant, and a proprietary adapter. It is a hardware device used for both device delivery and temporary pacing.

Based on the provided information, the Wattson™ temporary pacing guidewire is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use clearly states that the device is for introducing and positioning catheters and other interventional devices within the heart and for transmitting an electrical signal for temporary pacing. This is a direct interaction with the patient's body for a therapeutic and procedural purpose.
  • Device Description: The description details a physical guidewire with electrodes designed to be inserted into the heart.
  • Lack of In Vitro Activity: There is no mention of the device being used to examine specimens (like blood, tissue, or urine) outside of the body to provide information about a physiological state, health, or disease.

IVD devices are used to perform tests on samples taken from the body to diagnose, monitor, or screen for diseases or conditions. The Wattson temporary pacing guidewire does not perform this function. It is an invasive medical device used directly within the patient's circulatory system for procedural support and temporary pacing.

Dear Nancy Frame:

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 (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.

DEVICE DESCRIPTION

The Wattson temporary pacing guidewire is a dual-purpose 0.035" guidewire designed for the delivery of devices and for temporary rapid pacing of the heart. The distal end of the device has an atraumatic pigtail shape. The shaft of the device has a silicone lubricant applied to the outer surface.

Rapid pacing is achieved through a bipolar electrode configuration integrated in the shaft of the guidewire. The electrodes terminate in a single positive electrode at the distal tip of the device and three discrete negative electrodes located proximal to the tip within the pigtail section. The entire device is visible using standard fluoroscopic methods.

The device is packaged with a proprietary adapter that locks on to the proximal end of the guidewire and converts it to discrete positive and negative terminal pins. The terminal pins of the adapter are compatible with standard external pulse generators.

The Wattson temporary pacing guidewire is sterilized with ethylene oxide.

INDICATIONS FOR USE

The Wattson temporary pacing guidewire is intended to introduce and position catheters and other interventional devices within the chambers of the heart, including those used within transcatheter aortic valve replacement (TAVR) procedures and balloon aortic valvuloplasty (BAV), while transmitting an electrical signal from an external pulse generator to the heart. The temporary pacing guidewire is not intended to remain in place following the clinical procedure.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICES

This submission is seeking the clearance of the Wattson temporary pacing guidewire which has similar uses, fundamental technologies, principals of operation and performance as the identified predicate devices. The Wattson temporary pacing guidewire is similar to the Confida Brecker wire in that it is used to introduce and position catheters during diagnostic and interventional procedures within the chambers of the heart. It is similar to the Bard Temporary Pacing catheter in that it is used to transmit an electrical signal from an external pulse generator to the heart. Where there are technological differences, results of bench and animal tests confirm that the Wattson temporary pacing guidewire is substantially equivalent to the predicate devices. A comparison of the technological characteristics for the Wattson temporary pacing guidewire against the predicate devices is as follows:

Biocompatibility Testing

The biocompatibility evaluation for the Wattson temporary pacing guidewire was conducted in accordance with the International Standard ISO 10993-1 "Biological Evaluation of Medical Devices -Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The Wattson temporary pacing guidewire is considered an externally communicating device in contact with circulating blood and tissue for a limited period of time (
