This malfunction / defect has happened to us at least five times.We know of other facilities that have had similar problems with this device.The argyle peritoneal dialysis catheter has a defect on certain lots where the diameter of the catheter is too large in diameter to pass through the peel-away sheath provided.We used components of a different lot of the same item to challenge this hypothesis and were able to determine that it was the catheter and not the peel-away sheath that was defective.This was an issue as when the sheath is fully inserted into the patients abdomen.This is a crucial point in the procedure where you do not want any delays or problems while attempting to insert the catheter.Fda safety report id # (b)(4).
