The event was initially reported on 5/8/2017; however, the event did not meet mdr criteria until 5/30/2017 when it was reported that the catheter was cracked/split.The device was returned for analysis; however, analysis has not yet begun.Additional information will be submitted within 30 days of receipt.

As reported by a healthcare professional an envoy catheter (67025690b/ 17641208) would not advance up the cordis sheath, and when it could advance it was stiff and caused the envoy to break (cracked/split) at the distal tip.The same issue occurred 2 days running (additional complaint added).This hospital has used the same setup including the catheter and sheath and has had this issue occur a few times in the last calendar year; however, all complaints were reported to the manufacturer.The device was used as per the ifu, and a flush had been maintained.It was reported that the catheter and sheath was available for analysis.

As reported by a healthcare professional, an envoy catheter (67025690b/17641208) would not advance up the cordis sheath, and when it could advance, it was stiff and caused the envoy to break (cracked/split) at the distal tip.The device was used as per the ifu, and a flush had been maintained.It was reported that the catheter and sheath was available for analysis.A non-sterile envoy 6f, xb mpc was received inside of an unknown pouch inside of a plastic bag.No damages were noted on hub of the envoy.The envoy body was inspected and it was found kinked at 9.2, 18.2, 32.5, 45.8,54 59.5 and 89 cm from the proximal end of hub.No damages were noted on brite tip zone.The id and od from the envoy were measured and were found within specification.The functional analysis was performed.The envoy received was flushed using a lab sample syringe.The water came out from the distal end of the device.A 0.038¿ guide lab sample was introduced into the envoy and it advanced smoothly until to the envoy distal tip and resistance was found when the guidewire was passed through the kinked sections found on the catheter body.The envoy was introduced into the cordis cannula lab sample and it advance until the cannula distal tip end and resistance was felt in the brite tip fuse area.However, it passed totally through the brite tip fuse area of the cannula lab sample.A review of the manufacturing documentation associated with this lot 17641208 presented no issues during the manufacturing or inspection process that can be related to the reported complaint.The distal tip damage¿ was not confirmed.The difficulty passing the catheter through the introducer sheath was also not confirmed; however, there was resistance at the brite tip fusion area.The damages found on the received device were apparently caused by applying excessive force on it, but it could not be conclusively determined.These defects could not be related to the manufacturing process and procedural factors appear to have contributed to have this damage.Additionally, inspections are in place that prevents this kind of failure from leaving the facility neither the analysis nor the dhr suggest that the failure reported by the costumer could be related to the manufacturing process; therefore, no corrective action will be taken at this time.
