Manufacturing review: the lot records have been reviewed with special attention to the manufacturing and inspection of this product and the product was found to have met the specification prior to shipment.The review showed that no remarkable incidents occurred during the manufacturing process.No relevant manufacturing process changes were implemented, that could have led to the event reported.No additional complaint has been reported for this lot number previously.Investigation summary: based on the investigation of the returned catheter sample a failure to advance over the guidewire or a difficult wire advancement could not be confirmed.During evaluation a system compatible guidewire could be easily inserted and fully advanced without difficulty, and the stent could be further deployed easily at a low force level.A stuck guidewire was not part of the return.The safety clip was not attached to the system upon sample receipt and the stent was partially released; it was not known when and how this partial deployment was caused.The alleged stuck guidewire could not be reproduced and the investigation will be closed with inconclusive result.No indication could be found for a process related issue.Based on the information available and the evaluation of the sample returned a definite root caused could not be identified.Labeling review: in reviewing the labeling applicable it was found that the instructions for use (ifu) sufficiently describe the potential issue.The ifu states: 'visually inspect the bard lifestar vascular stent system to verify that the device has not been damaged due to shipping or improper storage.Do not use damaged equipment.(.) take care to avoid unnecessary handling, which may kink or damage the delivery system.' and 'should unusual resistance be felt at any time during the procedure, the entire system (introducer sheath or guiding catheter and stent delivery system) should be removed as a single unit.' furthermore, the ifu demands for sufficient flushing of the delivery system through both luer lock adapters.In regards to guidewire, the ifu states: 'the bard® lifestar¿ vascular stent system is only compatible with a 0.035¿ (0.89 mm) guidewire.' the intended application represents an off label use of the device; the bard lifestar vascular stent system is indicated for the treatment of iliac occlusive disease in patients with symptomatic vascular disease of the common and/or external iliac arteries.(b)(4).
