Event Description
|
It was reported that the blade separated and remained inside patient.The 90%, in-stent re-stenosed target lesion was located in the mildly tortuous and severely calcified left anterior descending (lad) artery.A 15mmx3.00mm wolverine coronary cutting balloon was used.During procedure, a 2.0/15 non-boston scientific product was advanced after an unknown wire crossed the area and laser was performed.Subsequently, the balloon was delivered and inflated at 12atm, 6atm, 6atm, 6atm and 12atm respectively, but failed.A diamond back was performed in the mid lad.The effect of ablation was sufficiently obtained.This device was delivered again, and dilation was performed 13 times (repeated 6atm to 18atm).After retrieval, it was noticed that the blade was separated.On the first usage, it was not separated, so it was certain that it became separated on the second usage.It could not be seen by fluoroscopy, so it could not be retrieved and remained in the body.The procedure was completed by a drug coated balloon.No further patient complications were reported, and patient was in good condition.

The device was returned for analysis.A visual examination identified that the balloon was returned in a deflated state.The balloon had been subjected to positive pressure.Three blades were present on the balloon surface, however, blade damage was noted.The midsection of the first blade was detached from the pad; the distance from break point to break point measured approximately 5mm.The pad remained attached and secure to the balloon material.The distal section of the second blade was detached; the distance from the break point to the distal edge of the pad was approximately 5mm.The pad remained attached and secure to balloon material.The proximal end of the mid blade section was found to be lifted from the pad.Areas of lift had occurred through the third blade.The third blade remained in the pad and the pad was secure to the balloon material.A visual and tactile examination found no issues with the shaft of this device.No issues were noted with the tip of the device.A visual and microscopic examination found no issue with the marker bands.
