Event or Problem Description
|

Each of the reported burs that wobbled were initial use, not reprocessed, and some wobbled right out of the package.To troubleshoot the issue, the doctor tried using the burs in different handpieces, to see the result.Each of the burs wobbled in a second handpiece; however, it was found that there was variability on how much of a wobble was evident with each handpiece (either more wobble, or less).The facility determined that this was an issue with their handpiece.

H3 the product analysis result indicates that there was no damage to the opened bur, which would have resulted in the reported malfunction.The product instruction states, ¿bur assembly shall lock into skeeter handpiece at 700 rpm using oto-tool console indicator without noticeable wobble, visually 100%¿.The returned sample was placed into the handpiece and ran at 1000 rpm [the console minimum rpm is 1000]; there was no ¿noticeable¿ wobble with an unaided eye.When viewed under magnification, there was no visible damage to the green teflon bushing/sleeve.The bur run at 16,000 rpm and cut saw bone with no issues.There is no geometric dimensioning and tolerancing on the applicable drawings that control the reported wobble [i.E., runout, concentricity, true-position].A review of the global complaint data showed only this facility reporting multiple lots with the same failure mechanism.There was no evidence of improper manufacturing and no fault related to the complaint; therefore, manufacturing ruled out as a potential cause.In the returned condition, there was no out-of-condition condition that is likely related to the complaint.H6: additional information suggest that fdm 4114 , fdr 3221 and fdc 67 are no longer applicable to this event.There were 2 devices used in the surgery and were submitting 2 mdrs for the same event list of products involved: bur 3155637 oto-flex.7mm carbide green lot no.219854403 regulatory rep # 1045254-2020-00510 drill 3055601 skeeter oto-tool serial no.Sk-u10340 lot no.216881241 regulatory rep # 1045254-2020-00511 bur 3155637 oto-flex.7mm carbide green lot no.220076447 regulatory rep # 1045254-2020-00512 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.
