Reportable based on the investigation completed on (b)(4) 2014.It was reported that a kink in the telescope was noted.During a procedure, an opticross¿ imaging catheter was used in order to visualize the unspecified target lesion.However, a kink in the telescope section of the device was then observed.The device was then exchanged with another of the same device in order to complete the procedure.No patient complications were reported and the patient's condition is good.However, returned device analysis revealed an open hole at the sheath lap joint section of the device.

Device evaluated by manufacturer: the complaint device was received for evaluation.After device analysis, no kinks were observed along the length of the catheter.The telescope assembly was not able to properly pull back, advance, and retract.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.Fluid was leaking at the sheath lap joint junction between the blue sheath and clear imaging window tubing.During image characterization testing, no image appeared in the system due to electrical open at proximal.Imaging core windup was found in the telescope assembly.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).
