E1.Initial reporter city: (b)(6).Wolverine cb mr, ous 10mmx2.50mm balloon delivery system was returned for analysis.A visual examination of the balloon identified blood inside the balloon.This blood is consistent with a leak having occurred in the device.The returned device was attached to a boston scientific encore inflation unit and positive pressure was applied to inflate the balloon however, the balloon failed to inflate.The failure to inflate the balloon is consistent with the build-up of solidified blood in the device.As a result, the device was soaked at 37 degress celsius in a watherbath in an attempt to dissolve the solidified blood.A second attempt was later performed at inflating the balloon when a pinhole leak of liquid was observed to be leaking from the balloon.The pinhole leak was located in the mid-section of the balloon.An examination of the balloon material identified no issues with the balloon which could have contributed to the pinhole leak.The markerbands and blades and tip section of the device were visually and microscopically examined, and no issues were noted with the markerbands, blades or tip of 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 found no issues with the shaft of the device which may have potentially contributed to the reported incident.No shaft kinks were noted at the distal end of the tip.No other issues were identified during the product analysis.
