The following issue was reported by a distributor, concerning a ct low profile titanium 6.6fr smartport: "the catheter could not be removed from the port site incision, therefore, the neck incision had to be reopened.It was also advised that the catheter was noted to be rough/ irregular on its exterior and the sheath had to be peeled off the catheter to facilitate removal.On doing so, a chalky residue was noted within the sheath and adherent to the catheter itself.After peeling this off, the catheter could then be removed.Patient had prolonged operating time and required an additional incision to remove the port.".

Returned for evaluation was one (1) smartport with catheter tubing.As received, the catheter was approximately 24cm in length and was attached to the smartport.The catheter appeared rough in appearance.It could not be determined what caused the catheter surface to become rough and difficult to remove.No manufacturing non-conformances were observed during sample review and the catheter met dimensional specifications.The customer's reported complaint description of catheter was difficult to remove (at end of device use/treatment) was confirmed as the exterior of the catheter tubing had a rough surface indicating it was adhered to tissue and/or fibrin sheath.A definitive root cause for the customer experience with this device could not be determined.This most likely contributed to the difficult to remove catheter event experienced during the port explant procedure.However, we are unable to determine an exact root cause for the rough exterior surface.No manufacturing related non-conformances were observed during evaluation of the returned port/catheter tubing.Port placement, patient anatomy and drugs used during the 2+ year treatment are potential contributing factors of the rough catheter surface and the difficult to remove catheter tubing.A review of the device history records was performed for the indicated lots for any deviations related to the reported failure mode of the complaint. the review confirms that the lots met all material, assembly and performance specifications; i.E.No ncr associated with reported failure mode.Labeling review: the instructions for use, which is supplied to the user with this catalog number, contains the following statements: absence of a blood return or a poor blood return can be a sign of a potential complication such as occlusion, kinking, breakage, pinch-off syndrome, fibrin formation, thrombosis or malposition.This should be evaluated prior to device usage.A blood return should be present prior to usage of device for any therapy or testing.If the patient complains of pain, or if there is swelling when the device is flushed or when medication or contrast media is administered, evaluate the device for infiltration, proper needle placement, and potential complications such as occlusion, kinking, breakage, pinch-off syndrome, thrombosis or malposition.Failure to assess these complaints or observations can lead to device failure.Caution: avoid piercing catheter with suture needle.Potential complications: catheter fragmentation and catheter pinch-off.Catheter placement considerations: warning: avoid medial catheter placement into sub-clavian vein through percutaneous technique.This placement could lead to catheter occlusion, damage, rupture, shearing, or fragmentation due to compression of the catheter between the first rib and clavicle.Catheter shearing has been reported when the catheter is inserted via a more medial route in the subclavian vein.A review of the angiodynamics complaint system noted no adverse trends for this complaint type and product family.This type of complaint will continue to be monitored for trends.Reference (b)(4).
