🎯 Root Cause Analysis
Primary Cause: Hardware fault in the QDOT catheter's force sensor signal path, likely triggered by re-insertion handling.
Technical Details:
Micro-damage to force sensor wires or strain gauge during manipulation
Possible connector contamination (blood, saline, condensation)
Internal catheter circuit failure due to flexion stress or ESD event
Contributing Factors: Connection instability at PIU, frequent patch disconnections added noise but were not root cause.
💡 Clinical Recommendations
Immediate Action: Quarantine and return failed catheter for manufacturer analysis
Procedure Review: Inspect handling procedures to minimize connector contamination during re-insertion
System Check: Verify all cables and patches are firmly connected before procedure start
Documentation: Log catheter serial numbers and report to J&J quality assurance team
