Event Description
|
It was reported that a tear in the guidewire exit port occurred.The 100% stenosed target lesion was located in a severely tortuous and mildly calcified middle right coronary artery.An opticross¿ imaging catheter was selected for use.After pre-intravascular ultrasound (ivus), the physician tried to cross the opticross¿ imaging catheter to the lesion to perform ivus; however, it was noticed that the transducer moved in a strange direction during removal.Furthermore, it was noted that the guidewire exit port was torn when the opticross¿ was visually checked.The procedure was completed with a non-bsc device.No patient complications were reported.

Manufacturer Narrative

Device evaluated by mfr: the device was returned for analysis.Device analysis revealed a damaged on the guidewire exit port assembly.A test guidewire (0.014") was inserted and no indication of resistance in tracking the guidewire into the catheter was noted.It was observed that the catheter flushed normally when the imaging core was fully retracted and fully advanced.Impedance testing shows a good unit wave form.During image characterization testing, a good square image appeared in the ilab 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 most probable root cause is operational context as device performance was limited due to anatomical procedural factors.(b)(4).
