Event or Problem Description
|
|
The patient was undergoing a coil embolization procedure in the anterior communicating artery (acom) using penumbra smart coils (smart coils), a penumbra smart coil detachment handle (handle), a non-penumbra microcatheter and a non-penumbra stent device.During the procedure, the physician used the stent device to hold open the vessel, then, the smart coil was successfully implanted into the target vessel using the handle and microcatheter.While advancing the next smart coil through the microcatheter, the physician encountered resistance but was able to reach the target location.After making an attempt to detach the smart coil using the handle, the physician was unsure whether it detached or not, and made an attempt to manually detach it.The physician was still unsure whether the smart coil truly detached; therefore, it was withdrawn.Upon removal of the pusher assembly, the physician realized that the smart coil had detached in the microcatheter; therefore, it was completely removed.The next smart coil was advanced approximately 10 centimeters into the same microcatheter and became stuck.The physician suspected that the microcatheter was occluded and decided to remove the smart coil and flush the microcatheter on the back table.While flushing the microcatheter, a small residue covered in blood emerged.Subsequently, the same microcatheter was re-advanced into the target vessel.While advancing the next smart coil through the microcatheter, the physician encountered resistance and upon removal, noticed that the pusher assembly had kinked in a "wave" form.The smart coil was discarded.Upon further analysis, the pusher assembly of all three complaint coils exhibited the same kinking.The procedure was completed using another smart coil, the same handle, the same microcatheter, and the same stent device.There was no report of an adverse effect to the patient.

Please note that the device in complaint was not expected to be returned; however, on 15-apr-2020 the device was received.Based on this information, corrections were made to: 4.Section h.Box 6: method code 1, method code 2, and method code 3.5.Section h.Box 6: results code 1.6.Section h.Box 6.Conclusions code 1.Results: the pet lock was intact on the proximal end of the pusher assembly.Bends were present at the mid-joint approximately 139.0 ¿ 145.0 cm from the proximal end.Additional bends were present throughout the length of the pusher assembly.The lamination was intact on the pusher assembly flexible braided shaft.The embolization coil was intact with the pusher assembly and had offset coil winds.A small fibrous material was within the specimen bag with the cotton swab.No other substances were on the swab or within the specimen bag.Conclusions: evaluation of the returned smart coil confirmed kinks and bends on the pusher assembly mid-shaft and revealed offset coil winds on the embolization coil.If the device is forcefully advanced against resistance, damage such as these may occur.During functional testing, the smart coil was advanced through a demonstration microcatheter with resistance due to the bends on the pusher assembly.Further evaluation revealed additional bends along the pusher assembly.These bends were likely incidental to the reported complaint.Evaluation of the returned cotton swab revealed an unknown material.All components of the returned smart coil were intact.The source of this material was unable to be determined.Penumbra coils 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: 1.3005168196-2020-00469.2.3005168196-2020-00470.
