Reportable based on device analysis completed on (b)(6) 2014.It was reported that kinked and leakage occured.The 75% stenosed target lesion was located in the moderately tortuous and non-calcified left anterior descending (lad) artery.During the percutaneous coronary intervention (pci) outside the patient, an opticross imaging catheter was used to view the lesion.It was noted that the connection area of the opticross got kinked.During flushing, leakage occured at that kinked connection part.The procedure was completed with another of the same device.No patient complications were reported and the patient's status was good.However, device analysis revealed a hole at the sheath lap joint area of the catheter.

Device evaluated by manufacturer: the complaint device was returned for analysis.Evaluation of the returned device revealed that the no kink or leak was found in the telescope section of this catheter.A kink was observed in the imaging window assembly at 67.1 cm from femoral marker at the distal end.Open hole at the sheath lap joint assembly.Fluid was found leaking from an open hole at the lap joint area when the catheter was flushed.The imaging window was still connected to the blue sheath tubing at the lap joint.The telescope assembly was not able to properly pull back, advance, or retract.Since the telescope cannot advance the transducer distal housing (tdh) to the most distal position, the distance from the distal end of the transducer housing to the tip of the catheter was not measured.During image characterization testing in the roller coaster model, a good square image appeared in the system.No other issues or defects were observed during product analysis of the returned device.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The root cause is not confirmed as there was no evidence of the alleged issue or any anomalies which could have contributed to the reported difficulty.(b)(4).
