Manufacturer Narrative

Hw: software analysis could not confirm the reported behavior.It was determined that low performance errors were observed during navigation, which could have led to the system freeze.However, there were no user reports of low performance warnings.There was insufficient information to determine whether a software anomaly contributed to the reported behavior.Software analysis also found a "segfault" during application exit.This finding was unrelated to the reported behavior of system becoming unresponsive.The "segfault" was found in the settings manager (in libcrypto library) during the application exit, but the application session was found to be exited normally.The occurrence of the fault did not cause the system to freeze during navigation.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.

Manufacturer Narrative

H2/h3/h6: further software analysis was completed.Low performance errors were observed during the navigation.There were two cases of low performance that got captured in the logs.1) when gpu occupancy was less than 80% but was more.User was not notified with any message and ui operations would not be impacted mostly.2) when gpu occupancy was more than 80% but was more.User was not notified with low performance message and users face application freeze or any other unexpected issues.Logs in this case captured the above stated first scenario.It was unclear if the low performance error may have led to the system freeze.Codes b01, c19 and d15 are applicable.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
