Event Description

The patient was undergoing medical procedure in the mesenteric artery using a benchmark 6f 071 delivery catheter (benchmark).During the procedure, the physician placed a stent device in the target vessel using the benchmark.While attempting to advance a second stent device through the benchmark, the physician experienced resistance and the stent device became stuck inside the benchmark.Therefore, the physician removed the benchmark and the stent device altogether and decided to end the procedure at that point.There was no report of an adverse effect to the patient.

Manufacturer Narrative

Results: the benchmark 6f 071 delivery catheter (benchmark)was repeatedly kinked approximately 27.0 to 32.0 cm from the hub and ovalized approximately 105.0 cm from the hub.During functional analysis, a stainless steel mandrel was advanced into the benchmark and friction was observed when advancing through the kinks in the proximal shaft.The mandrel could not be advanced through the ovalized distal shaft.Conclusions: evaluation of the returned device revealed that the benchmark had multiple consecutive kinks in the proximal shaft.This damage likely occurred due to forceful retraction of a stent against resistance or at an angle.Further evaluation revealed the benchmark was ovalized on the distal tip.This damage may have occurred due to forceful manipulation of the benchmark during navigation of patient anatomy.The distal ovalization likely contributed to the inability to advance the second stent device during the procedure.The stent device mentioned in the complaint was not returned for evaluation.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.
