The device was returned for analysis.The reported loose or intermittent connection was unable to be confirmed.The returned guiding catheter was connected to the copilot bleedback control valve (bbcv) rotator, forming a secure connection.There were no anomalies noted to the connections as reported.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents from this lot.As the reported loose or intermittent connection was unable to be confirmed during return analysis, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that a buildup of procedural contaminants (blood, contrast) on the device and/or the device was not completely connected/fully tightened thus resulted in the reported loose connection.There is no indication of a product quality issue with respect to manufacture, design or labeling.
