The customer states during ultrasound guided insertion, the guide wire passed through the needle and the two dilators passed over the guide wire well.When the catheter was passed over the guide wire and the proximal end of the guide wire exited the venous port it was frayed.The guide wire and catheter were removed from the patient and another catheter was inserted with no problems.Anecdotally, the doctor also commented that approximately 6 months ago he had heard that another resident had the distal end of the guide wire fray during the insertion of a triple lumen catheter being inserted in the icu.He had no other details regarding that incident.
