As reported by the smart pms for sfa study, approximately five years post implantation of a smart (smart control, iliac 6x80) self¿expanding stents (ses) on the middle portion of the left femoral artery, the patient developed in-stent restenosis confirmed by an echography.Then, a revascularization was performed in the middle portion of the left femoral artery and a non-cordis stent was implanted.Twenty-seven days, the patient recovered.The event was not related with the cordis product.

After further review of additional information received the following sections have been updated accordingly.Additional information received indicates that the target lesion was the middle of the left femoral artery.The vessel level of calcification is moderate.The vessel level of angulation is none.The length of the lesion was 60-millimeters (mm).The diameter of the vessel was 5.8-millimeters (mm).Only one stent was places in the lesion.Five years after a smart (smart control, iliac 6x80) self¿expanding stent (ses) was implanted in the middle portion of the left femoral artery, the patient developed in-stent restenosis confirmed by echography.A revascularization was performed and a non-cordis stent was implanted and the patient recovered.The vessel level of calcification is moderate.The vessel level of angulation is none.The length of the lesion is 60 millimeters.The diameter of the vessel is 5.8 millimeters.The device was not returned for analysis.A product history record (phr) review of lot 15680147 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The phr review does not suggest that the event reported by the customer could be related to the manufacturing process.The reported ¿in-stent arterial restenosis¿ could not be confirmed as procedural films were not received.Thrombosis, stenosis, and/or restenosis are commonly indicated events.Patients that require stents typically exhibit signs of thrombosis and restenosis prior to receiving these devices.Restenosis is a common adverse event of endovascular procedures.Damage to the blood vessel wall by angioplasty triggers physiological response that can be divided into two stages.The first stage that occurs immediately after tissue trauma, is thrombosis.A blood clot forms at the site of damage and further hinders blood flow.This is accompanied by an inflammatory immune response.The second stage tends to occur 3¿6 months after surgery and is the result of proliferation of cells in the media, a smooth muscle wall in the vessel.This is also known as neointimal hyperplasia.Reports of these conditions after the device has been successfully deployed have not been linked to known manufacturing processes or criteria of the stent.According to the instructions for use, which is not intended as a mitigation, the following events are amongst those listed as potential adverse effected secondary to intravascular stent implantation: arterial occlusion/thrombus, remote from puncture site, arterial occlusion/restenosis of the treated vessel, embolization, arterial, ischemia/infarction of tissue/organ, venous occlusion/thrombosis, remote from puncture site.Neither the phr nor the information available suggests a design or manufacturing related cause for the reported event; therefore, no corrective/preventive action will be taken at this time.
