Additional Manufacturer Narrative
The device has been returned and the investigation results are pending.A follow up mdr will be submitted upon completion of the device investigation.This report is associated with mfr report numbers: 3005168196-2019-02445, 3005168196-2019-02447.
Event or Problem Description
The patient was undergoing a thrombectomy procedure in the left middle cerebral artery (mca) using a penumbra system jetd reperfusion catheter (jetd), neuron max 6f 088 long sheath (neuron max) and, velocity delivery microcatheter (velocity).During the procedure, the physician placed a neuron max in the left internal carotid artery (ica), a velocity was then used to bring up the jetd through the neuron max and into the target vessel.Afterward, the physician removed velocity; however, resistance was encountered while retracting the velocity out from the jetd.It was reported that the physician thought there might be something wrong with the jetd; therefore, it was removed.However, while retracting the jetd out of the neuron max, the physician experienced resistance and the jetd proximal end began to collapse.The physician also thought there might something wrong with the neuron max distally; therefore, the neuron max was also removed.The procedure was completed using a new jetd, neuron max and the same velocity.It was also reported that after the procedure, the first neuron max was examined, and the distal end was found to be kinked.There was no report of an adverse effect to the patient.
Additional Manufacturer Narrative
Results: the neuron max was kinked approximately 54.0, 77.5 and 89.0 cm from the hub.Conclusions: evaluation of the returned jetd confirmed an ovalization on the distal shaft.If the neuron max became kinked while the jetd was inserted into the device and the jetd is retracted, damage such as an ovalization may occur.In addition, resistance may also be experienced during retraction of the jetd out of the neuron max.Further evaluation revealed additional ovalizations on the proximal end of the jetd.If the device is retracted from the neuron max at extreme angles outside of the patient, damage such as ovalizations may occur.During functional testing, resistance was experienced while advancing the jetd through a demonstration neuron max due to the proximal ovalization and the jetd could not advance any further.Evaluation of the returned neuron max confirmed a kink on the distal shaft.If the device is advanced against resistance, damage such as a kink may occur.During functional testing, resistance was experienced while attempting to advance the returned jetd through the neuron max due to the kink and the jetd could not be advanced any further.Penumbra catheters are inspected during in-process inspection and during quality inspection after manufacturing.The product lot number was not provided, therefore, the manufacturing records could not be reviewed.This report is associated with mfr report numbers: 1.3005168196-2019-02445, and 2.3005168196-2019-02447.H3 other text : placeholder.
