Manufacturing review: the device history records have been reviewed and this lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Investigation summary: one dorado pta dilatation catheter was returned for evaluation.Frayed fibers were noted on the balloon; no other anomalies were noted on the returned device.On the functional evaluation the device was inflated with an in-house presto inflation device and water was noted leaking from the distal tip.Then the balloon was cut and under the microscope it was noted a partial break in the inner guide wire lumen.No other testing was performed.No evidence of balloon rupture noted during the functional testing.One video was reviewed.The balloon was noted to be bloody and noted to be in an inflated position.Water was leaking from the guide wire luer; however, the source of the leak is unknown.No evidence of balloon rupture noted on submitted video.Therefore, based on the video review, the reported balloon rupture remains inconclusive.Therefore, the investigation for the reported balloon rupture remains inconclusive as there is no evidence of balloon rupture noted during functional testing and the submitted video.However, the investigation was confirmed for the identified inner guide lumen rupture as a partial break on the inner guide wire lumen noted during the microscopic observation.The investigation was also confirmed for identified frayed fibers as frayed fibers were noted on the balloon during the visual evaluation.A definitive root cause for the reported balloon rupture and identified inner guide wire lumen rupture and frayed fibers could not be determined based upon the provided information.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.(expiry date: 08/2022).
