Our product evaluation lab received one model 140806 adherent clot catheter without any attached components.The customer report of the latex membrane got torn was confirmed.As received, a tear was observed on latex membrane.The tear size was approximately 1 mm x 1 mm.After cutting the proximal and distal membrane bonding site, the edges of the tear appeared to match up.Per edwards ifu, exposure to the atmosphere, handling during insertion, and plaque and other deposits within the blood vessel may cause latex membrane degradation.And to minimize the risk of vessel or membrane damage, do not exceed the maximum recommended pull force.No visible damage was observed from catheter body.Both the core wire and the thumb slide on the handle were functional.An engineering evaluation was initiated to assess for any manufacturing related processes which could be correlated to the complaint.The customer report of broken catheter was confirmed with objective evidence through the product evaluation.Based on the available information there is no evidence that supports or confirms the failure mode is associated to a manufacturing/ design defect.As part of the manufacturing process, 100% of units go through visual inspection to verify general appearance, contamination, length of the tube, diameter of the bonding and spiral coil verification in closed position.Also, a 100% inspection of the functionality of the handler is performed activating it 3 consecutive times to verify the behavior of the coils, spiral and latex membrane integrity.A device history record review was completed and documented that device met all specifications upon distribution.
