Event Description
|
It was reported that the balloon and shaft got separated.The 90% stenosed target lesion was located in the mildly tortuous and mildly calcified superficial femoral artery.A 4.00mm/1.5cm/140cm small peripheral cutting balloon was selected for use.During the procedure, when the protector was removed for pcb preparation, it was very difficult to pull out.Consequently, a slight force was applied but the balloon and shaft got separated.The procedure was completed with a different device.No complications were reported, and patient was good post procedure.

Manufacturer Narrative

Device evaluated by manufacturer: the device was returned for analysis.The device was received in two sections due to a separation of the shaft.The device was returned with the balloon protector partially removed on the device.For investigation purposes the investigator fully removed the protector without issue.A visual examination identified that the balloon was not subjected to positive pressure.The balloon material and blades of the device were visually examined, and no issues were noted.A visual and tactile examination found the shaft polymer extrusion to be completely separated at the guidewire port.The shaft was also found to be kinked at approximately 80mm distal of the separation.This type of damage is consistent with excessive force being applied to the device.The device was received with the balloon protector partially removed on the device.The investigator was unable to apply a vacuum to the device as per preparation instructions indicated in spcb ifu due to a shaft separation.For investigation purposes the investigator removed the balloon protector from the device.The balloon protector inner diameter was verified at 0.0435 inch using a calibrated pin gauge.This is within the specified range of 0.0420 inches to 0.0435 inches as per drawing.Balloon protector 3.5mm thru 4mm.A visual investigation identified no damage or any issues with the markerbands or tip of the device.
