The patient was undergoing a coil embolization procedure using penumbra smart coils (smart coils).During the procedure, while attempting to insert a smart coil into the hub of a non-penumbra microcatheter, the physician experienced resistance at the distal tip of the smart coil introducer sheath; therefore, the smart coil was removed.Upon removal, the physician inspected the smart coil on the back table and noticed that it would not advance out of the tip of its introducer sheath.The procedure was completed using another smart coil, other coils and the same microcatheter.There was no report of an adverse effect to the patient.
