This carotid artery stenting procedure was performed in (b)(6).During the procedure on the carotid artery, the physician felt the spiderfx delivery catheter was caught by the protégé rx stent upon removing from the patient.The filter of the spiderfx became caught by the stent, and the physician could not retrieve the spider filter from the patient.Therefore, the physician used a different delivery catheter (4fr angiographic catheter) to retrieve the spider filter from the patient.The filter was removed from the patient successfully.However, the protégé rx stent partially broke.The physician also noted the stent deployed inside the patient looked like a heart shape.The physician determined no additional approach to the lesion was possible.Please reference mdr 2183870-2015-00015 for the spiderfx used in this procedure.
