Analysis/device evaluation: upon receipt, visual examination was performed revealing the proximal end of the balloon was wrinkled and a kink was found on the shaft at the proximal balloon bond.Functional testing determined the balloon was unable to be fully inflated due to damage to the balloon.Next, microscopic visual inspection revealed the balloon material was longitudinally torn between the middle of the balloon and the distal end of the balloon.The damage was observed on both sides of the balloon, thus, destructive evaluation of the balloon was performed, which revealed the inner lumen was also longitudinally damaged with markings on both sides in the same region as the outer balloon material.A lot history review revealed this is the only complaint associated with balloon rupture for this lot.A device history record (dhr) review was performed and noted the device was manufactured to specification prior to being released for distribution.A formal investigation was performed to determine the root cause of the inner lumen damage.The root cause investigation found a manufacturing related issue associated with the inner lumen damage.Steps were taken to address the root cause.This event occurred prior to the introduction of additional manufacturing processes and tests being implemented.Conclusion: returned product analysis confirmed the balloon was not able to be inflated.The root cause was due to a longitudinal material rupture, which was between the middle and the distal end of the balloon.The damage with markings was also noted on the inner lumen of the catheter shaft in the same location as the outer balloon damage.A formal investigation was performed to determine the root cause of the inner lumen damage.The root cause investigation found a manufacturing related issue associated with the inner lumen damage.Steps were taken to address the root cause.This event occurred prior to the introduction of additional manufacturing processes and tests being implemented.

It was reported a lutonix percutaneous transluminal drug coated balloon (dcb) dilatation catheter allegedly was unable to inflate during treatment of the target lesion.The health care professional (hcp) used a contralateral approach to treat the right lower popliteal artery.The pathway and the lesion were not tortuous or calcific in nature, thus the hcp was able to maneuver the balloon to the target lesion without difficulty.While inflating the balloon, it would not increase pressure and the contrast solution was leaking from the balloon.The hcp removed the balloon in its entirety, without difficulty.The hcp does not believe the anatomy or the target lesion morphology caused or contributed to the contrast leaking from the balloon.Another device was used to complete the procedure.The lutonix dcb was returned for evaluation.No adverse patient effects were reported.
