One 75 mm tacticath quartz contact force ablation catheter was received for evaluation.Visual inspection revealed fluid outside of the irrigation tubing but within the tygon tubing just distal to the luer hub.Further investigation revealed a short circuit between e1 and e3, consistent with the reported event.In addition, dried saline was noted within the connector plug, consistent with the short circuits detected.The device no longer met specifications during shaft leak testing and irrigation leak testing.Further testing revealed a gap in the adhesive between the irrigation tube and the proximal tube inside the luer lock, allowing fluid to flow outside of the irrigation tubing and into the proximal tubing towards the optical and electrical connectors, consistent with the dried saline noted within connector plug and the shaft and irrigation leaks.
