Event Description

The patient was undergoing an embolization procedure by flow diversion in the internal carotid artery (ica) using a neuron 6f 070 delivery catheter (neuron 070) and a neuron max 6f 088 long sheath (neuron max).During the procedure, the physician experienced resistance while attempting to advance a neuron 070 through the neuron max and subsequently, the neuron 070 was unable to advance through the neuron max.Therefore, the neuron max was removed.The physician then attempted to insert the same neuron 070 into a new neuron max; however, the same issue occurred.Therefore, the neuron 070 was removed.The procedure was completed using a new neuron 070 and the same second neuron max.There was no report of an adverse effect to the patient.

Manufacturer Narrative

Evaluation of the returned neuron max revealed a functional device.During the functional test, the returned neuron 070 could not be advance through the neuron max due to the distal ovalization.A stainless-steel mandrel was advanced through the returned neuron max without an issue.Evaluation of the returned neuron 070 revealed ovalization on the distal shaft.If the peel-able sheath (supplied by penumbra) is not used to protect the distal shaft during insertion, damage such as ovalizations may occur.Further evaluation revealed a kink underneath the strain relief.This damage was likely incidental to the reported complaint.Penumbra 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: 3005168196-2020-01569.
