Event or Problem Description
It was reported to boston scientific corporation that an axios stent and electrocautery enhanced delivery system was intended to be implanted in the transgastric to retrieve a pancreatic fluid collection during a cystgastrostomy procedure performed on (b)(6) 2026.During the procedure, when the physician was attempting to deploy the stent after unlocking the black arrow lock switch and squeezing grey handle, the knob of the device broke into two pieces.The axios was unable to deploy so the physician removed the handle and stent.The procedure was able to be completed by using another of the same device.There were no patient complications reported as a result of this event.Note: it was reported that the physician rotated the entire handle during the procedure.Per the ifu (instructions for use) routine rotation of the axios handle itself is not part of stent deployment or positioning.Rotation is only referenced for specific locking/unlocking steps, not for advancing, retracting, or deploying the stent.
