Intended Use

Medtronic diagnostic catheters are intended for use in diagnostic electrophysiologic procedures. The catheters are designed for recording intracardiac electrograms and temporary pacing associated with electrophysiology studies.

Device Story

Flexible, radiopaque diagnostic catheters; constructed of extruded polymer over stainless-steel braid; feature platinum-iridium sensing band electrodes. Used in clinical electrophysiology labs by physicians to record intracardiac electrograms and provide temporary pacing. Catheters are steered to specific cardiac locations; electrical signals are captured via electrodes and transmitted to external recording/pacing equipment. Output allows clinicians to map cardiac electrical activity and assess conduction, aiding in diagnosis of arrhythmias. Benefits include precise intracardiac signal acquisition and temporary pacing capability during diagnostic studies.

Clinical Evidence

Bench testing only. Design verification testing performed on samples subjected to accelerated aging (equivalent to 2-year shelf life). Testing included corrosion resistance, visual inspections, dimensional measurements, actuation force, tip springback, deflection/planarity, stiffness/flexibility, kink resistance, lateral stability, torqueability, tensile testing, electrode impedance/resistance, and simulated use. Packaging testing included sterilization/environmental pre-conditioning, label legibility/durability, and bubble leak testing.

Technological Characteristics

Flexible, radiopaque catheters; extruded polymer over stainless-steel braid; platinum-iridium band electrodes. Steerable design. Dimensions and materials unchanged. Sterilization process unchanged. Standalone device; no software or electronic processing components.

Indications for Use

Indicated for use in diagnostic electrophysiologic procedures, specifically for recording intracardiac electrograms and temporary pacing associated with electrophysiology studies in patients undergoing such procedures.

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 Matthew Lobeck:

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. The 510(k) Premarket Notification Database located 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

While this premarket notification covers changes to labeling, packaging design and materials, and product requirement specifications, there are no changes to the finished diagnostic catheter designs or materials. The manufacturing processes and inspections related to diagnostic catheter assemblies are also remaining unchanged. Compared to the predicate, the subject device features the:

- Same intended use ●
- Same indications for use .
- Same fundamental scientific technology ●

{7}------------------------------------------------

- Same finished catheter design and dimensions ●
- . Same user interface
- Same materials of construction ●
- Same manufacturing and sterilization processes ●

The differences between the subject and predicate devices involve labeling, packaging, and product requirements only. The subject device design technology, performance characteristics, materials, shelf life and sterilization process are all unchanged.

The proposed changes do not constitute a change in the fundamental scientific technology for the subject devices and do not raise new or different questions of safety and effectiveness. The subject devices do not provide a new therapy, and the intended use and indications for use remain unchanged and identical to the predicates. The modified subject devices described in this 510(k) submission are substantially equivalent to the predicate devices.

Performance Data: Performance testing (bench) was completed in support of the proposed modifications. The results of the design verification testing completed in support of the proposed changes demonstrate that the diagnostic catheters in scope of this premarket notification meet all applicable proposed product requirements.

> To support the proposed product requirement changes in this premarket notification, the following tests were performed on test samples exposed to accelerated aging conditions equivalent to the product shelf life of 2 years:

### Product Requirement Testing:

## Conclusion:

This premarket notification is limited to labeling, packaging design and materials, and product requirement specifications for Medtronic diagnostic catheters. There are no changes to the intended use, indications for use, performance, or fundamental scientific technology, and the subject devices are considered substantially equivalent to the legally marketed predicate devices.
