The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other complaints reported from this lot.Because it was reported that the herculink elite was being used to treat a subclavian artery, it should be noted that the indication section of the herculink elite instruction for use (ifu) states: the rx herculink elite renal stent system is indicated for use in patients with atherosclerotic disease of the renal arteries following sub-optimal percutaneous transluminal renal angioplasty (ptra) of a de novoor restenotic atherosclerotic lesion(= 15 mm in length) located within 10 mm of the renal ostium and with a reference vessel diameter of 4.0 ¿ 7.0 mm.Suboptimal ptra is defined as = 50% residual stenosis, = 20 mmhg peak systolic or = 10 mmhg mean translesional pressure gradient, flow -limiting dissection, or timi [thrombolysis in myocardial infarction] flow < 3.In this case, the off-label use does not appear to have contributed to the reported difficulties.Based on the information provided, a definitive cause for the reported leak and hub crack could not be determined.It may be possible that the rotator on the inflation device was over-tightened onto the treads causing the hub to crack and resulting in leak; however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.D9, h3 - device status changed from returning to discarded.

It was reported that the procedure was to treat an unspecified lesion.A 7x15mm herculink was advanced to the lesion and inflated once at 4 atmospheres, when leakage was noted coming from the hub due to a crack.An unspecified balloon was used to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.Subsequent to the initially filed mdr, it was confirmed that the procedure was to treat a subclavian artery stenosis.No additional information was provided.
