The contact at the hospital reported that during the post-endovascular aneurysm repair of coil embolisation of the patient¿s left subclavian artery a presidio coil (b)(4) was stuck in the prowler select plus (b)(4) and could not be detached using the enpower control cable (b)(4).The patient¿s vessels were heavily tortuous and heavily calcified.It was reported that an okay ii (goodman, type unknown), and an enpower dcb (lot unknown) were also used for the above procedure.The complaint presidio was the 3rd coil to be inserted.It was reported that the dpu of the complaint presidio was stuck inside the mc while the physician was placing the microcoil into the target lesion site.Thus, the physician was unable to maneuver the presidio to fully place the microcoil into the target site.Since almost the entire microcoil was already placed in the target site, the physician attempted to detach the coil.However, despite pressing the detach button a number of times, the physician was unable to detach the microcoil.The physician concluded that to continue using the complaint presidio would be hazardous, therefore it was safely removed together with the complaint prowler from the patient.The microcoil was also safely removed.With a new presidio, prowler, and cable (all details unknown), the physician was able to complete the procedure without further issues or delay.The complaint products were new and stored per labeling instructions.The procedure was conducted in accordance with the ifu and the constant flush had been maintained at all times.No visible defect (kink, bends, etc.) were noted on the devices prior to the events.A pre-deployment electrical check was performed and there was no report of any abnormal behavior of the dcb.The green system ready light illuminated.During the detachment cycle the detachment light illuminated.All connections appeared to fit properly without application of excessive force.Due to the fact that the patient was a hcv carrier, the complained products have already been safely disposed.No further information is available.
