Reportable based on device analysis completed on (b)(4) 2014.It was reported that catheter kinked and lost image occurred.The 90% stenosed target lesion was located in the moderately tortuous and mildly calcified distal of right coronary artery.During the percutaneous coronary intervention (pci), an opticross¿ imaging catheter was used to view the lesion.It was reported that the opticross¿ was kinked at the connection part of the blue and clear shaft then the image disappeared.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 an open hole at the lap joint area of the catheter.

Age at time of event: 18 years or older.(b)(4).Device evaluated by manufacturer: the complaint device was returned for analysis.Evaluation of the returned device revealed that no kinks were observed along the length of the catheter.The telescope assembly was able to properly pull back, advance, and retract.The distance from the distal end of the transducer housing to the tip of the catheter measured 25 mm.The observed distance is not within specification.Fluid was leaking from an open hole at the lap joint area when the catheter was flushed.The imaging window is still connected to the blue sheath at the lap joint.Device was inserted into test dispenser coil.Leak is located on the outside edge of the device.During image characterization testing in the roller coaster model, a good square image appeared in the system and the product performed within specification.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).
