Indications for Use

The Medtronic Ablation Frontiers Achieve Mapping Catheter is indicated for multiple electrode electrophysiological mapping of the cardiac structures of the heart, i.e. recording or stimulation only. The Achieve Catheter is designed to obtain electrograms in the atrial regions of the heart.

Device Story

Achieve™ Mapping Catheter is an intra-cardiac electrophysiology recording catheter used for mapping electrical conduction and cardiac stimulation. The device features a distal circular loop with eight evenly spaced electrodes. It is used in clinical electrophysiology procedures by physicians to obtain electrograms in atrial regions. The catheter connects via a dedicated electrical cable to standard electrophysiology recording and pacing equipment. The device is delivered through a compatible delivery catheter. By providing multi-electrode mapping, it assists clinicians in evaluating cardiac arrhythmias, potentially improving diagnostic accuracy during electrophysiology studies.

Clinical Evidence

No clinical data provided. Evidence consists of in vitro bench testing and in vivo performance testing. Bench testing verified mechanical integrity (rotational motion, insertion/retraction, torque, fatigue, buckling), electrical safety per ISO 60601-1:2006, and corrosion resistance per ISO 10555-1:2009. Biocompatibility was confirmed per ISO 10993 standards, including cytotoxicity, sensitization, systemic toxicity, pyrogenicity, hemolysis, and complement activation.

Technological Characteristics

Catheter body: Pebax (distal) and stainless steel (proximal). Distal loop: Nitinol insulated with PET and Pebax cover. 8 electrodes. Loop diameters: 15 mm and 20 mm. Diameter: 3.3F. Effective length: 146 cm. Connectivity: Dedicated electrical cable to standard ECG pins. Sterilization: Single-use. Standards: ISO 60601-1 (electrical safety), ISO 10993 (biocompatibility), ISO 10555-1 (corrosion).

Indications for Use

Indicated for multiple electrode electrophysiological mapping (recording or stimulation) of cardiac structures, specifically atrial regions. Contraindicated for ablation, use with transeptal sheaths having side holes >1.00 mm, retrograde approach, or patients with active systemic infection, left atrial thrombus, pulmonary vein stents, prosthetic heart valves, myxoma, interatrial baffle/patch, or acute myocardial infarction.

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.

### Device Description:

The Achieve™ diagnostic mapping catheter is an intra-cardiac electrophysiology recording catheter and can be used for cardiac stimulation during electrophysiology studies. The distal mapping section of the Achieve catheter is a circular loop with eight evenly spaced electrodes to map electrical conduction within the atrium. The Achieve catheter should only be used with the corresponding electrical cable for Achieve. The Achieve catheter is available with two distal loop diameter sizes described in the following table:

| Model | Loop Diameter |
|------------|---------------|
| 990063-015 | 15 mm |
| 990063-020 | 20 mm |

The sterile, single use only Electrical Cable (Model 990066) provides the conduction elements from the proximal end of the Achieve Catheter handle to standard shielded ECG pins that connect into standard electrophysiology recording and pacing equipment.

### Indications for Use:

The Medtronic Ablation Frontiers Achieve Mapping Catheter is indicated for multiple electrode electrophysiological mapping of the cardiac structures of the heart, i.e. recording or stimulation only. The Achieve Catheter is designed to obtain electrograms in the atrial regions of the heart.

# Contraindications:

The catheter is contraindicated as follows:

- For use as an ablation device .

- An active systemic infection ●
- Left atrial thrombus .
- Pulmonary vein stents .
- Prosthetic heart valve (tissue or mechanical) .
- Myxoma ◆
- Interatrial baffle or patch ●
- Conditions where the manipulation of the catheter within the heart would be unsafe �
- Acute myocardial infarction .
