Review of device history records including raw material inspection, in process & finished product inspection does not reveal any discrepancy relevant to the batch under investigation, which confirms that there is no indication of a product related quality deficiency associated to this batch.Control sample test results confirm that there was no indication of a product quality deficiency in the batch under investigation.Additionally, review of the complaint history identified no other similar incidents reported from this lot.Based on the available information and investigation outcome, it was presumed that a damage guidewire might have resulted to the reported incident.It is likely that the guidewire may have encountered resistance while manipulation & subsequent damage during advancement and/or withdrawal attempts.Therefore, the reported balloon catheter stuck over the guidewire appears to be related to circumstances of the procedure.The availability of the guide wire used is unknown.Without the concomitant device and the guidewire used, it is not possible to draw a clinical conclusion between the device and the reported event.Considering above and as clinical situations cannot be duplicated in our analysis lab, a conclusive cause for the reported incident, and the relationship to the product, if any, cannot be determined.Neither the dhr review nor the control sample analysis including complaint history review suggests that the reported failures could be related to the design or the manufacturing process.(b)(4).
