This complaint was found during a recent clinical evaluation review/literature search of this device.The citation is as follows: kindel, m., & spiller, p.(2002).Transient occlusion of an angioguard protection system by massive embolization during angioplasty of a degenerated aortocoronary saphenous vein graft.Catheterization and cardiovascular interventions, 55(4), 501-504.Complaint conclusion: as noted in the literature publication, kindel et al transient occlusion of an angioguard protection system by massive embolization during angioplasty of a degenerated aortocoronary saphenous vein graft; cathet cardiovasc intervent 2002;55:501¿504; report a case of massive embolization associated with transient occlusion in which larger distal embolization and myocardial infarction were avoided despite transient but complete occlusion of a filter protection system.The product was not returned for analysis.Additionally, as the sterile lot number was not available, device history record review could not be performed.An angioguard filter is indicated for use as a guidewire and embolic protection system to contain and remove embolic material (thrombus/debris) while performing carotid artery angioplasty and stenting procedures in carotid arteries for patients in which antiplatelet and/or anticoagulant therapy is contraindicated, the guide catheter is unable to be placed, have uncorrected bleeding disorders, known allergies to nitinol, and lesions in the ostium of the common carotid artery.Occlusion of the filter does not represent a device malfunction.Clinical factors that may have influenced the event include patient, pharmacological and lesion characteristics.Given the limited information available for review at this time, there is nothing to suggest that the reported event is related to the design and/or manufacturing process of the device; therefore, no corrective action will be taken.Should additional information become available, the file will be updated accordingly.
