A facility reported that an attempt was made to remove the patient's lumbar drain per standard protocol.The drain was not initially difficult to remove but after continued gentle removal, the drain was found to be structurally compromised, and a portion of the hermetic lumbar catheter, closed tip (ins5010) separated and remained in situ.Inspection of the removed segment revealed degradation of the catheter material.Imaging was ordered and showed the "retained lumbar drain catheter entering the spinal canal at l3-l4 and terminating at l1.The retained catheter is pinched between the l3 and l4 spinous processes." the site was sutured to prevent further csf leakage, and the retained drain scheduled to be removed in the or the following day.The lot number is unknown as the packaging wasn¿t saved.Injury is severity level 2: temporary or minor harm/damage.Slight injury; treatment required.Will require surgical intervention for retained hardware.

Updated fields: d4, d9, g3, g6, h2, h3, h6, h11.The hermetic lumbar catheter (ins5010) was not returned; therefore, failure analysis is not possible.In addition, no photos showing the reported condition have been provided, therefore, the complaint is considered unconfirmed.Lot number information has not been provided; therefore, device history record (dhr) could not be reviewed.However, each catheter tubing lot must meet incoming inspection requirements that include break load force, elongation, raw material tensile strength, id, and od.Due to no product return, the root cause cannot be determined.However, a possible cause could be related to having to pull too strongly on the catheter since, as reported, it was ¿pinched between the l3 and l4 spinous processes¿.Another possible cause could be related to manipulating or repositioning the catheter through the tuohy needle during its insertion.This can damage the catheter with the tuohy¿s edges and then breaking off during its removal when pinched between the mentioned spinous processes.If additional relevant information becomes available in the future, this complaint will be reopened, and the respective evaluation performed.Trends will be monitored for this and similar issues.At present, we consider this complaint to be closed.
