This was reported as a venotomy closure of the right common femoral vein using a prostyle device via an 8f sheath hole after an atrial fibrillation ablation procedure.Reportedly, the plunger could not be fully depressed, and the physician manipulated (pushed, pulled, wiggled, shifted) the plunger.The plunger was eventually repositioned, the lever was re-closed, and the device was withdrawn from the patient anatomy without issue.The suture was not deployed when the device was removed.The physician believed the issue may have been due to the spring in the plunger.Manual compression was used to achieve hemostasis.There was no adverse patient sequela and no reported clinically significant delay in the procedure or therapy.No additional information was provided.

Analysis was performed on the returned device.The reported mechanical jam plunger and plunger retraction were not confirmed.However, a proxy plunger was inserted into the device and the plunger fully deployed without resistance.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 similar incidents from this lot.The investigation was unable to determine a conclusive cause for the reported difficulties.Factors that may contribute to a mechanical jam (plunger deployment issue) include, but are not limited to, needle deflection during plunger deployment due to interaction with patient anatomy (human tissue, calcified femoral vessel, etc.) or failure to maintain a stable position of the device with respect to the tissue tract.Factors that may contribute to plunger retraction problem include, but are not limited to, user closes foot before suture deployment (i.E., before plunger fully retracted proximally) or suture snag.The treatment appears to be related to circumstances of the procedure.Based on the information reviewed, there is no indication of a product quality issue with respect to manufacture, design or labeling.
