Manufacturer Narrative
Patient information was not made available from the site, this hospital refused requests for patient demographic information. On 07/15/2016 a medtronic representative reported while in the optical cranial biopsy program, the magnetic resonance imaging (mri) was thresholded by the stealth nurse in the room, and the patient was registered. During the biopsy, the surgeon placed a navigus probe into the glass tube, the entry was set, the foot-pedal button was pressed and the typical audible beep was heard, however, the program did not auto forward to a lock trajectory window. Since the surgeon could not lock trajectory when putting the biopsy needle in the reducing tube, it would not recognize it. Attempted to use a new biopsy needle, re-booted the navigation system and the software application, however, this did not resolve the issue. Re-registering the patient on a second navigation system also did not improve results. The surgeon opted to re-schedule the procedure. On 07/15/2016 a medtronic representative performed a navigation system check-out, all areas passed. System performed as intended. On 07/29/2016 a medtronic representative, following-up at the site, reported the second procedure was successful, the same burr hole was used. Although the site refused to provide patient demographic information, it was noted that this patient was not obese. No parts were replaced. No parts have been received by manufacturer for analysis. No further issues have been reported.
 
Event Description
A medtronic representative reported that, while in a cranial biopsy procedure, the surgeon inserted the navigus probe into the guide stem, however, the views did not switch to guidance view automatically and locking trajectory was not an option. In trouble-shooting, it was discovered that custom procedures were created and labeled "optical biopsy" however, they were not created from the "biopsy" procedure so the functionality was not available as an option. Delay in therapy was greater than one hour, at this point, the surgeon opted to halt the procedure and re-schedule. Per a medtronic representative attending the procedure, the navigation system was fully functional.
 
Manufacturer Narrative
A medtronic representative reported that the patient was an older female. The delay to the surgery was 1. 5 to 2 hours. The site would not share any other information. Correction: the investigation found that the issue was caused by user technique and there was no product problem. The software investigation found that the reported event was unrelated to a software issue. Per the reported event, it was discovered that custom procedures were created, labeled "optical biopsy" but were not created from the "biopsy" procedure so the functionality was not available. The software functioned as designed.
