Intended Use

For use in cardiac electrophysiology procedures to assist in the diagnosis of arrhythmias that may be difficult to identify using conventional mapping systems alone (i.e., linear mapping catheters). The Ablacath™ Mapping Catheter may also be used for delivery of externally generated pacing stimuli.

Device Story

Ablacath™ Mapping Catheter is a sterile, single-use, high-density array intracardiac mapping catheter. Device features an expandable basket distal end with 8 longitudinal splines, each containing 8 electrodes (64 total). Integrated introducer tool collapses basket for insertion into 8.5 F sheath. Operated by electrophysiologists in clinical settings to detect electrical potentials from endocardial surfaces. Signals are transmitted to a 3-D mapping system for analysis. Device also delivers externally generated pacing stimuli. Provides high-density electrical data to assist in diagnosing complex arrhythmias. Benefits include improved diagnostic capability over conventional linear catheters.

Clinical Evidence

No human clinical data. Evidence includes extensive bench testing (mechanical, electrical, radiopacity, corrosion, tensile, packaging/sterilization) and GLP-compliant animal studies (swine model). Animal studies confirmed performance, acute safety, and usability requirements, with physician end-users finding the device clinically acceptable and equivalent to the predicate. Biocompatibility testing performed per ISO 10993-1:2018.

Technological Characteristics

Nitinol struts; Pebax spine tubes and catheter tubing; gold-plated copper electrodes. 64 electrodes in unipolar or bipolar configuration. 8-spline expandable basket (50mm or 60mm). 2.8 mm shaft diameter, 128 cm length. EO sterilized (ISO 11135-1). Electrical rating: ±30 V, 25 mA. Dielectric strength: 500 VDC. Standards: ASTM F1980 (aging), ASTM F640 (radiopacity), ISO 10555-1 (mechanical), ISO 10993 (biocompatibility).

Indications for Use

Indicated for patients undergoing cardiac electrophysiology procedures requiring diagnosis of arrhythmias difficult to identify with conventional linear mapping catheters; also indicated for delivery of externally generated pacing stimuli.

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.
