The user facility reported that a 6 french 90cm destination sheath was placed into the left brachial artery and extended into the distal aorta.An 035 rubicon catheter was placed into a small branch off the right internal iliac artery and a 018 thruway wire was placed.The 2.4 french progreat was placed over the wire with great resistance felt by the technologist loading it.It was noted by the physician that the technologist was accidentally pinning the catheter tip and pushing the back end of the catheter.After the technologist repositioned their hands, the catheter was able to be delivered to the appropriate location over the wire.The wire was removed, and the 018 10cm hydopack coil was introduced.One coil was successfully delivered.The second coil was delivered; however, intended to be repositioned and upon removal, the coil became detached due to resistance and the tail of the coil was hanging into the common iliac artery in an unwanted location.The progreat was removed; however, it was elongated and partially torn.The physician decided that no additional intervention was necessary at this time.The procedure performed was a type 2 endoleak embolization of right internal iliac branch.The patient had a prior 10cm aaa with prior endovascular surgery.The estimated blood loss was less than 250cc's.The coil was unable to be pulled back into the catheter and caused poor coil positioning.There was no direct allegation that the reported device caused or contributed to patient injury and/or need for medical intervention.
