Event Description

Manufacturer Narrative

Engineering analysis: the complaint details provided indicate that the stent dislodged off the balloon within the introducer sheath.The returned device balloon surface was evaluated to determine if the stent was crimped properly during manufacturing.The crimped stent impressions were clearly visible indicating that the stent was properly crimped during manufacturing.The crimped stent diameter was measured and was 2.14mm.This diameter when compared to the lot qualification test data falls within the same range of diameters that are only slightly smaller.The slightly larger diameter is due to the stent being pulled over the folded balloon cones.The introducer sheath used in the case was not returned.Engineering summary: a full review of the catheter lot history records for the device in question was performed.The records indicate that this lot of catheters passed atriums final lot qualification testing.This inspection requires that the catheter lot must pass the following: ability of the stent and delivery system to be passed through the labeled introducer sheath.Ability to deploy the stent at nominal pressure (8atm).Ability to withdraw the deflated balloon catheter back through the labeled introducer sheath.Ability of the delivery system to withstand 10 inflate/deflate cycles at the rated burst pressure (12atm) without leaks or failures.Balloon burst testing.The balloon must burst over the rated burst pressure specified on the label (12atm).Manifold to shaft tensile testing.Samples when tensile tested must not break or separate below 3.37lbs.Result: all (b)(4) quality inspection samples passed this final inspection without any non-conformances noted during the final lot qualification testing related to the stent.All samples passed through the introducer sheath without any stent dislodgments.Conclusion: based on the details of the event and the successful lot qualification test data, atrium can find no fault with the device and or lot of stent delivery systems in question.
