Manufacturing review: the device history records were reviewed with special attention to the raw materials, subassemblies, manufacturing process and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Investigation summary: the device was returned for evaluation.A visual inspection found a small hole in the catheter shaft near the proximal glue joint.Therefore, the investigation is confirmed for a hole.The investigation is also confirmed for slight peeling of the outer pebax layer on the balloon.The device was inflated and water was noted to be exiting the balloon.The balloon fibers were stripped and a partial circumferential rupture was noted in the balloon material.Therefore, the investigation is confirmed for a circumferential rupture.It is likely that the circumferential rupture contributed to the identified peeled pebax.Per the reported event details, the patient's lesion was calcific and a wall stent was present.Therefore, it is unknown if patient factors or the wall stent contributed to the reported rupture.However, the definitive root cause for the rupture or hole in the catheter shaft could not be determined based upon the available information.Labeling review: the review of the ifu (instructions for use), indications, warnings, precautions, cautions, possible complications, and contraindications showed that the product labeling is adequate.( expiry date (08/2021).
