As reported, midline picc placed in upper right arm about 24 hours prior to failure.When placed, it was confirmed with x-ray to be in good position in the distal svc.It flushed well after insertion and had good blood return.The next day the midline would not flush properly, and had issues receiving a blood return.The nurse at the time complained it was hard to flush and admitted to pushing hard on the syringe.The angiodynamics clinical specialist present with the nurse was suspicious that she used excessive force to flush the catheter.He accompanied the vascular access nurse to the bedside and found the picc to be leaking at the site.As the line was needed to administer anesthesia prior to surgery, the midline was pulled from upper right arm and replaced in the upper left arm and the new midline worked appropriately.The removed picc was found to contain a slit at approximately the 4-5 cm mark.The used device has been returned to angiodynamics for evaluation.

A review of the device history records was performed for the indicated packaging and component lots for any deviations related to the reported defect of the complaint.The review confirms that the lots met all material, assembly and performance specifications.The september 2017 angiodynamics complaint report was reviewed for the bioflo picc product family and the failure mode "catheter - hole distal to suture wing." no adverse trend was identified.As received, the catheter contained a slit in the catheter distal to the suture wing.The slit was between the 3-4 cm mark and was approximately 1/2 cm long.The slit was longitudinal in nature, which is consistent with a catheter tubing that has been over-pressurized.The catheter tubing was sectioned just distal from the split hole at approximately the 2 cm mark.Visual inspection of this cross section cut did not show any abnormalities/thin spots.The following tip dimensions were verified using pin gauges and calipers with the aid of a microscope: id height of "d" lumen, septum wall, tubing wall, tubing od.All were found to meet specification.A definitive root cause for the hole in the catheter tubing could not be determined based on the sample review and information received from the end user, however, it is likely that the tubing was over-pressurized.Potential root cause for an over-pressurized picc device include incorrectly performed ct power injection (e.G.Flow rate too high, contrast not warmed) or injection/flushing through an occluded lumen.The directions for use provided with the picc device include recommended flushing procedure as well as precautions on avoiding tubing damage.Angiodynamics' manufacturing process controls include in-process visual inspection for damage or defects, a guidewire insertion test for lumen patency, and 100% sprint testing after the guidewire verification to ensure that the catheters do not leak.((b)(4)).
