Intended Use

The catheter is indicated for electrophysiological mapping of cardiac structures in adult patients; i.e., stimulation and recording only.

Device Story

MultiCath and AcQRate Dx Fixed Curve Catheters are pre-shaped multipolar catheters used for sensing intracardiac signals and diagnostic pacing. The device comprises a catheter body with a distal curve, an array of platinum/iridium electrodes, and a proximal multipolar connector. Used in clinical electrophysiology labs, the device is operated by qualified medical personnel in conjunction with an external electrophysiological investigation and recording system. The catheter is inserted into the patient to map cardiac structures; the electrodes transmit electrical signals to the recording system or deliver pacing stimuli. Healthcare providers use the recorded intracardiac signals to diagnose cardiac arrhythmias or guide electrophysiological procedures. The device is single-use and supplied sterile.

Clinical Evidence

No clinical performance data was submitted or relied upon. Substantial equivalence is supported by bench testing, including dimensional inspection, functional/compatibility testing with external generators, electrical/mechanical testing, biocompatibility (ISO 10993), and sterilization validation (ISO 11135).

Technological Characteristics

Multipolar catheter with platinum/iridium electrodes; 4F, 5F, and 6F diameters; pre-shaped distal curves. Materials meet ISO 10993 biocompatibility standards. Electrical safety complies with IEC 60601-1. Sterilization via ethylene oxide per ISO 11135. Connectivity via multipolar connector to external recording/stimulation systems. Internal braid design for torque control.

Indications for Use

Indicated for electrophysiological mapping of cardiac structures in adult patients for stimulation and recording purposes.

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.

### Catheter

### Device Description [807.92(a)(4)]

The MultiCath* and the AcQRate Dx Fixed Curve Catheter are pre-shaped multipolar catheters for sensing of intracardiac signals and diagnostic pacing, in combination with an electrophysiological investigation and recording device.

The device consists of a catheter body with a distal curve, an array of platinum/iridium (PtIr) electrodes, and a proximal multipolar connector. Multiple electrode configurations are available with various numbers of electrodes and electrode spacing.

* Unless otherwise noted, the term "MultiCath" is used throughout to represent either MultiCath or the AcQRate Dx Fixed Curve Catheter.

{4}------------------------------------------------

### Indications for Use [807.92(a)(5)]

The indications for use for the MultiCath Catheter and the predicate are the same.

The catheter is indicated for electrophysiological mapping of cardiac structures in adult patients; i.e., stimulation and recording only.

#### Comparison of Technological Characteristics with the Predicate Devices [807.92(a)(6)]

The MultiCath Catheters are substantially equivalent to the predicate devices based on comparisons of the device functionality, technological characteristics, and intended use. The differences in tip curvature offerings are minor and do not raise new issues of safety and effectiveness. The diameter and number of electrodes have been evaluated through bench and biocompatibility testing. Bench testing demonstrated that the subject device is substantially equivalent to the predicate device.

### Cable

### Device description:

BIOTRONIK's MPK-4-R and MPK-10 patient cables are four or ten channel cables to connect electrophysiological diagnostic catheters distributed by BIOTRONIK (e.g., MultiCath, ViaCath) and Acutus Medical (AcQRate Dx Fixed Curve Catheter, AcQ Dx Steerable Catheter) with electrophysiological examination units and stimulators.

### Intended use:

MPK-4-R and MPK-10-R are used to connect BIOTRONIK and Acutus Medical diagnostic catheters to a cardiac stimulator or a lab monitoring system for intracardiac diagnostics as part of an electrophysiological study. MPK-R and diagnostic catheters may only be used by medical personnel qualified to work with lab monitoring systems. Patient cables may not be physically modified, e.q., shortened.

### Functional and Safety Testing:

### Conclusions [807.92(b)(3)]

Based on the performance testing and the technological characteristics, it can be concluded that the MultiCath meets its established performance for its intended use and is substantially equivalent to the predicate device.
