Event Description
|
It was reported that balloon pinhole occurred.The 70% stenosed, 16x4mm, concentric target lesion contained >45 and <90 degree bend and was located in the non-tortuous and a non-calcified right coronary artery (rca).Following the insertion of a 6fr non-bsc guide catheter, a 3.5x38mm non-bsc stent was advanced and deployed to the target lesion.Subsequently, a 15mm x 4.00mm nc quantum apex¿ balloon catheter was selected for use and advanced for "post expansion" to improve stent expansion.However, when fluoroscopy was performed, filtration of the contrast was seen when the balloon was inflated.The physician reviewed the device and noted that the balloon has hole where the contrast escapes.The procedure was completed with a different device.No patient complications were reported and the patient status was stable.

Device evaluated by mfr.: returned product consisted of a nc quantum apex balloon catheter.The device was pressurized with an inflation device filled with water.A pinhole was identified in the shaft material at the proximal edge of the proximal balloon bond.There were scratches on the proximal balloon weld which extended to the balloon.Microscopic examination of the balloon presented no irregularities in the balloon material, shaft material or the ro marker that could have contributed to the damage.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.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).
