Event Description
|
It was reported that balloon rupture and removal difficulties occurred.The target lesion was located in the mildly tortuous and moderately calcified left anterior descending artery.A 10mmx2.50mm wolverine coronary cutting balloon was advanced and at the first dilation, the balloon ruptured at 5atm.The cutting balloon got stuck and could not be removed.The proximal part of the hub of the shaft was cut, and a non-bsc guide extension catheter was advanced to the part where the device was stuck.The balloon was released and removed together with the extension catheter.The procedure was completed with a different device.There were no patient complications reported.

Manufacturer Narrative

E1: initial reporter city: (b)(6).Device evaluated by mfr: the device was returned for analysis.A visual examination identified that the balloon was not folded which indicates that the balloon was subjected to positive pressure.Blood was identified inside the balloon which is evidence of a device leak.A leak test could not be carried out due to a separation of the hypotube.The rated burst pressure for this device is 12 atmospheres as per wolverine specification.The markerbands, blades and tip section of the device were visually and microscopically examined, and no issues were noted with the device that may have potentially contributed to the complaint incident.All blades were present and fully bonded to the balloon material.A visual and tactile examination identified a separation of the hypotube.It was reported that the physician cut the hypotube to remove the manifold of the device.The manifold was not returned for analysis.The hypotube was also found to be severely kinked at more than one location.This type of damage is consistent with excessive force being applied to the device.No other issues were identified during the product analysis.
