The catheter was returned and evaluated.A review of manufacturing records was performed and found that the device met specification when released to sterilization.The catheter was visually inspected and exhibited signs of obvious damage extending from the first row of holes distally.This type of damage is often seen when a catheter is inserted and then subsequently retracted.The sharp tip of the trocar can, on rare occasions, get caught in the distal holes.As the catheter is further extracted, the catheter is torn by the sharp end of the trocar.A portion of the distal catheter appears to be missing.The amount of catheter present on the returned part is insufficient to recreate an entire distal section.The following warning is included in the product insert to avoid this type of event from occurring: "to avoid damage to the catheter, care must be taken not to withdraw the catheter from the needle in order to reposition it in the subarachnoid space.If the catheter must be removed, withdraw the needle and catheter simultaneously." based on the evaluation of the device, the damage to the catheter was caused by retraction of the catheter after insertion without simultaneously retracting the needle, which is explained within the product insert.Trends will be monitored for this or similar complaints.At present, we consider this complaint to be closed.
