Event Description
|
It was reported that during the treatment of a micro- perforation to the m2 of the left mca, physician used the subject microcatheter and guidewires to deploy stent.He re-sheathed the stent and during deployment it was slightly migrated to forward direction while applying forward pressure to delivery system and covered the mca branch.15 minutes post deployment physician noticed contrast leaking distal to the stent indicating vessel perforation.On review of imaging, it was cleared that the perforation happened before stent deployment and after the placement of subject microcatheter and guidewires.It is undeterminable if the devices caused the perforation.Balloon angioplasty was performed to stop bleeding and protamine was administered to reverse heparin.4 hours post procedure patient started bleeding again at m1/m2 bifurcation.Another surgery was performed to remove the blood from brain and the stent was seen protruding from the vessel.It is undeterminable if the stent caused the perforation.Patient suffered paralysis and is currently in icu.No additional information available.

Manufacturer Narrative
|
Due to the automated manufacturing execution system (mes) system there are controls in the manufacturing process to ensure the product met specifications upon release.The subject device was not returned; therefore, physical as well as functional evaluation could not be performed.The reported event is covered in the device directions for use (dfu).The reported 'patient intracranial hemorrhage', ' patient neurological deficit' and 'patient vessel perforation' are documented as potential adverse events associated with the use of microcatheters or with the endovascular procedures, with in the device dfu.An assignable cause of anticipated procedural complication will be assigned to the reported complaint as a product related root cause does not apply and the issue is due to a known physiological effect of the procedure and/or patient condition noted with the directions for use, product labeling and/or risk documentation files.
