Event Description
|
It was reported that shaft break occurred.The 90% stenosed target lesion was located in a shunt of the left forearm.A non bsc guide wire crossed the lesion, then a 6.0-4/4t/90 symmetry balloon catheter was advanced for dilatation.However, it was noted that there was something like a 'crack' on the proximal shaft of the device and during inflation, the balloon was unable to be inflated.The device was removed from the non bsc sheath and was exchanged to 5.0-40/4t/90 symmetry standard balloon to complete the procedure.No patient complications were reported and patient's status was good.

Manufacturer Narrative

Device evaluated by mfr: a symmetry balloon dilation catheter was received for analysis.A visual and microscopic examination found no issues with the tip section of the device.A visual examination of the balloon confirmed that the balloon had been subjected to positive pressure.The balloon was fully detached from the shaft and it was visually noted that there was blood in the balloon which is indicative of a leak.The shaft was broken immediately proximal to the proximal end of the balloon.A visual and tactile examination found that the proximal end of the shaft was kinked along its length.This type of damage is consistent with the application of excessive force.The shaft outer diameter (od) was measured at an undamaged portion of the shaft which is within specification.No other issues were identified during the product analysis.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).
