Event Description
|
During treatment of anterior cerebral artery (aca) aneurysm, it was reported that the aneurysm ruptured after the deployment of the 5th coil.The compliant balloon was placed and inflated in the right a1 segment and the heparin was reversed to treat the rupture.The 6th coil was deployed and detached without issue.When the 7th subject device coil was deployed but produced a long cycle on detachment.It was presumed that the subject coil had not detached; therefore, the physician re-positioned (withdrawn slightly) the subject coil (and possibly the micro-catheter) to perform another detachment cycle; however, the subject coil had already detached.During re-positioning, an approximately 1cm of the subject coil tail migrated into the left a2 segment.At that time, no suitable retrieval devices were available, so the decision was made to deploy the stent to secure the subject coil tail.Thrombus formation was noted within the stent and the right a2 segment.The patient was administered with iv aspirin and reopro with good result.The patient was kept in icu overnight and is being slowly woken throughout the day today.No further information is available at this time.

Manufacturer Narrative

The device history record (dhr) review confirmed that the device met all material, assembly and performance specifications.The subject device was not returned; therefore, physical as well as a functional evaluation could not be performed.The reported event is covered in the device directions for use (dfu).As well, the risk of the reported event is documented in the risk documentation and there are current controls to mitigate the risk of the as reported event.As the product was not returned and review and analysis of all available information fails to indicate an assignable cause or probable assignable cause for the reported "main coil protrusion";therefore, an assignable cause of undeterminable will be assigned.Based upon medical review assessment, the data reasonably suggest the clinical event is anticipated in nature and severity as per the dfu and does not require escalation to senior management.An assignable cause of anticipated procedural complication, will be assigned to the reported "patient aneurysm rupture" and "patient vessel thrombosis", 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.
