Event or Problem Description
|
|
The patient was undergoing a coil embolization procedure to treat an arteriovenous malformation (avm) using ruby coils.During the procedure, the physician successfully placed several penumbra coils in the target vessel using a px slim delivery microcatheter (px slim).While advancing another ruby coil through its introducer sheath, the physician felt resistance and was unable to advance the ruby coil out of its introducer sheath into the microcatheter.The ruby coil was therefore removed and was not used in the procedure.The physician then attempted to advance another ruby coil; however, the same issue occurred.This ruby coil was also removed and was not used in the procedure.The procedure was completed using additional ruby coils and the same px slim.There was no report of an adverse effect to the patient.

Results: the pet lock was intact on the proximal end of the pusher assembly.The pusher assembly was kinked approximately 39.0, 77.0, and 122.0 cm from the proximal end.The pusher assembly was fractured approximately 124.0 cm from the proximal end.The embolization coil was intact with its pusher assembly.The pull wire was advanced distal to the distal detachment tip.Conclusions: evaluation of the first returned ruby coil revealed that the pusher assembly was fractured.If the device is forcefully advanced against resistance, damage such as a kinked pusher assembly may occur.If the kinked pusher assembly is subsequently manipulated, the kink may worsen to a fracture.In addition, the forceful advancement against resistance likely contributed to the pull wire protruding distal to the ddt.The root cause of the initial resistance could not be determined.The px slim identified in the complaint was not returned to penumbra for evaluation.Evaluation of the second returned ruby coil revealed that the embolization coil winds were offset along the length of the coil within its introducer sheath.If the ruby coil is forcefully advanced against resistance, damage such as offset coil winds may occur.Resistance was encountered while attempting to advance the ruby coil out of its introducer sheath during the functional test and the ruby coil could not be advanced any further.The root cause of the initial resistance could not be determined.The px slim identified in the complaint was not returned to penumbra for evaluation.Penumbra coils and catheters are visually inspected during in-process inspection and during quality inspection after manufacturing.The manufacturing records for this lot were reviewed and did not reveal any outstanding discrepancies, design, or quality concerns.This report is associated with mfr report number: 1.3005168196-2019-00368.
