Device evaluated by manufacturer: the device was returned for analysis.Analysis of the tip, distal shaft, collar, and hypotube included microscopic and visual inspection.Inspection revealed a complete separation of the collar/shaft with the polytetrafluoroethylene (ptfe) completely pulled out of the collar, and the tip was slightly damage (flared).Inspection of the rest of the device found no other damage or defect to the device.The inner diameter of the tip of the device and collar were measured with a calibrated pin gage.Both the tip and the collar measured.057", meeting the specification.The guidezilla catheter was separated at the collar/shaft connection, so functional testing with a balloon catheter was not possible.
