Intended Use

The BioTrace Medical Tempo Temporary Pacing Lead is indicated for use in temporary intracardiac pacing for a maximum of seven (7) days and is designed to transmit an electrical signal from an external pulse generator to the heart or from the heart to a monitoring device.

Device Story

Tempo Temporary Pacing Lead is a radiopaque, polymeric, bipolar, single-use transvenous lead; features balloon, active fixation, and soft tip. Provides right ventricular access via femoral, subclavian, or internal jugular vein. Transmits electrical signals between external pulse generator and heart. Used by clinicians in clinical settings (e.g., TAVR, valvuloplasty, EP procedures). Facilitates rapid pacing and cardiac monitoring. Benefits include stable pacing capture and reduced risk of dislodgement during procedures. Output used by physicians to manage heart rhythm; informs clinical decisions regarding pacing support.

Clinical Evidence

Prospective, multicenter, non-randomized, single-arm study (Tempo Study) of 25 patients undergoing TAVR, valvuloplasty, or EP procedures. Primary endpoints: safety (freedom from pericardial effusion/tamponade) and technical feasibility (delivery and pace capture). Results: 100% safety (no device-related adverse events); 92% technical feasibility. Average final procedural pace capture threshold (PCT) was 0.7±0.5 mA. No sustained ventricular arrhythmias or lead dislodgement reported. Follow-up to 30 days.

Technological Characteristics

Radiopaque polymeric lead; bipolar electrodes; active fixation; balloon-tipped; straight distal configuration with stabilizers. Dimensions accommodate 6F introducer sets. Single-use, sterile, non-pyrogenic. Biocompatibility testing per ISO 10993. Design verification includes bond joint strength, fatigue resistance, and corrosion resistance testing.

Indications for Use

Indicated for temporary intracardiac pacing for up to 7 days in patients requiring pacing for transcatheter aortic valve replacement (TAVR), balloon aortic valvuloplasty, or electrophysiology (EP) procedures.

### Technological Comparison:

For the purpose of demonstrating the substantial equivalence of the Tempo Temporary Pacing Lead in this 510(k), BioTrace Medical has selected the Medtronic Temporary Transvenous Pacing Lead System (Model 6416), #K042190. The Tempo Temporary Pacing Lead was assessed for substantial equivalence relative to the legally marketed predicate device with respect to intended use, indications for use, and technological characteristics as summarized below.

Testing Summary: To demonstrate intended device performance, as well as to support the substantial equivalence of the subject Tempo Temporary Pacing Lead to the predicate device, the technological and performance characteristics were evaluated by completion of the following testing:

- Design Verification ●
- > Bond Joint Strength
- > Fatigue Resistance
- > Corrosion Resistance
- > Simulated Use
- > Electrical Resistance
- Electrical Safety Testing ●
- Packaging Validation
- Sterilization Validation
- Shelf Life Testing (Accelerated Aging)

- > Cytotoxicity
- > Sensitization
- > Irritation Reactivity
- Systemic Toxicity A
- A Subchronic Toxicity
- > Genotoxicity

- Clinical Study:

The Tempo® Study was a prospective, multicenter, non-randomized, single arm study to evaluate the safety and effectiveness of the Tempo® Temporary Pacing Lead in patients requiring temporary cardiac pacing for transcatheter aortic valve replacement, balloon aortic valvuloplasty or electrophysiology (EP) procedures. Twenty five (25) patients were enrolled in two centers. The device was evaluated for safety (freedom from pericardial effusion requiring intervention and/or echocardiographic evidence of tamponade) and technical feasibility (intracardiac

delivery and pace capture). Additional evaluations included pace capture thresholds (PCT), success of rapid pacing, and incidence of dislodgement or sustained ventricular arrhythmias (>30 seconds). Transthoracic echocardiograms were obtained at baseline and 24 hours after lead removal. Follow up was to 30 days.

The safety endpoint was met in all patients (100%) with no device-related adverse events. The technical feasibility endpoint was met in 23 patients (92%). No patient had a sustained ventricular arrhythmia or lead dislodgement. Average final procedural PCT was 0.7±0.5 mA. Rapid pacing was successful in all cases, with no loss of pace capture. In 5 patients the lead was successfully used postprocedure.

This first-in-human study demonstrates that the Tempo Lead is safe and effective for temporary cardiac pacing.

The results from these tests and studies demonstrate that the technological and performance characteristics of the subject Tempo Temporary Pacing Lead are adequate for its intended use and ensure the subject device can perform in a manner equivalent to devices currently on the market with the same intended use.

Conclusion: The data and information presented within this submission (including in vitro bench, in vivo animal testing and the clinical study) support a determination of substantial equivalence of the Tempo Temporary Pacing Lead to marketed temporary pacing leads.
