Event Description
|
The patient was undergoing a thrombectomy procedure in the right m2 segment of the middle cerebral artery (mca) using a penumbra system 4max reperfusion catheter (4maxc) and a neuron max 6f 088 long sheath (neuron max).During the procedure, the physician placed the neuron max in the patient.Next, while advancing the 4maxc into the neuron max, the physician experienced resistance.Therefore, the physician decided to remove the 4maxc.Upon removal, the physician noticed that the mid-shaft of the 4maxc was broken.The procedure was completed using a new 4maxc and the same neuron max.There was no report of an adverse effect to the patient.

Manufacturer Narrative
|
Evaluation of the returned 4maxc confirmed a fracture on its mid-shaft.If the 4maxc is advanced at an extreme angle during use, damage such as a kink may occur.This damage likely contributed to the reported resistance during advancement.Subsequently, further manipulation of a kinked device may worsen to a fracture.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.
