Manufacturer Narrative

Results: the lantern was kinked approximately 6. 0 cm from the hub. Initially, the lantern was unable to be flushed. A demonstration coil was unable to be advanced past the proximal kink. A mandrel was advanced through the length of the catheter to facilitate the removal of the clot and flushing of the device. Subsequently, a demonstration coil was able to be advanced through the length of the returned lantern without issue. Conclusions: evaluation of the returned lantern revealed a kink on its proximal shaft. This kink may have been due to improper handling during preparation for use. During functional testing, a demonstration ruby coil was unable to be advanced past this proximal kink. After advancing a mandrel through the catheter to flush the device, the demonstration ruby coil was able to pass through the returned lantern without issue. Advancing the mandrel through the kink likely widened the lumen of the returned lantern resulting in the successful advancement of the demonstration ruby coil. If this kink was present during the procedure it would likely have contributed to the resistance experienced and early detachment of the embolization coils. Penumbra catheters are 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 numbers: 3005168196-2018-01157, 3005168196-2018-01158, 3005168196-2018-01159.

 
Event Description

The patient was undergoing a coil embolization procedure using ruby coils and a lantern delivery microcatheter (lantern). During the procedure, the physician felt resistance while advancing a ruby coil through the lantern and, consequently, the ruby coil unintentionally detached within the lantern. The physician therefore removed the rotating hemostatic valve (rhv) to pull out the ruby coil from the lantern. The physician then successfully placed another ruby coil. The physician then felt resistance while advancing another ruby coil within the lantern and, consequently the ruby coil unintentionally detached within the lantern. The physician again was able to remove the ruby coil by hand after removing the rhv. The physician then switched to a new lantern and successfully placed multiple ruby coils. However, the physician then felt resistance while advancing another ruby coil within its introducer sheath and into the lantern and thought that the pusher assembly was damaged, though no specific damage was noticed. The physician therefore removed the ruby coil. The procedure was completed using additional ruby coils, pod coils, and the same lantern. There was no report of an adverse effect to the patient.
