The Johnson & Johnson 34A15M (also referenced as 34JJ7M) is a 7F deflectable electrophysiology catheter from the UNI-NAVISTAR family, configured with a J-curve distal section, a 4 mm distal tip electrode, and a 115 cm usable length. The device is designed to support intracardiac signal acquisition and the delivery of radiofrequency energy during catheter-based ablation procedures.
Key Features
- 7F catheter shaft profile for compatibility with standard EP introducer sheaths
- J-curve distal deflection geometry to facilitate chamber navigation
- 4 mm distal tip electrode for focal mapping and RF energy delivery
- Electrode spacing pattern 1-7-4 mm across the distal array
- 8-electrode distal configuration for multi-site signal acquisition
- 115 cm usable catheter length for transvenous access approaches
- Compatible with the NAVISTAR / CARTO ecosystem as indicated by the UNI-NAVISTAR product family naming
- Single-use, sterile-packaged construction consistent with the J&J EP catheter line
Clinical Applications
- Diagnostic intracardiac electrogram recording during electrophysiology studies
- Catheter-based mapping of cardiac arrhythmia substrates
- Radiofrequency ablation workflows where a 4 mm tip J-curve catheter is selected by the operator
- Procedures performed in conjunction with compatible EP recording, stimulation, and RF generator equipment
- Use within hospital cardiac catheterization and electrophysiology laboratory environments
