Related manufacturing reference: 3005334138-2020-00106.Following an atypical right atrial flutter procedure, an entanglement requiring snare removal occurred.When the sheaths and catheters were being removed from the patient, withdrawal difficulty was noted with the advisor catheter.Flouroscopy confirmed the catheter was caused in the distal end of the sheath.Manipulation of the catheter was attempted to release the catheter and sheared the introducer that was adjacent to the device in two pieces.The proximal portion of the sheath was removed, but a snaring tool was utilized to remove the distal portion of the sheath, which appeared to be fully removed from the vein.It was indicated by the physician that the advisor had wrapped around the sheath and became entangled.The patient was stable and the procedure was able to be completed.There was no damaged noted to the catheter.

One fast-cath guiding introducer swartz sr series, sr0 8.5f was received for investigation.The reported event of catheter withdrawal difficulty could not be confirmed.The sheath tube had been stretched and torn into two sections.The sheath hemostasis cap inside diameter measurement was within specifications; however, the sheath distal tip inside diameter could not be measured due to distal tip damage.Functional testing could not be conducted due to the condition of the device.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.The cause of the reported catheter withdrawal difficulty remains unknown.The cause of the stretched and torn sheath tubing is consistent with damage during use.
