Event or Problem Description
|
|
Medtronic received a report that two axium prime coils initially failed to detach.The first coil unintentionally detached during removal, and the second was later able to be successfully detached.The patient was undergoing treatment for an unruptured, saccular aneurysm located in the left ic-anchro region.The max diameter was 3.5mm, and the neck diameter was 1.6mm.The patient's blood flow was normal, and the vessel tortuosity was moderate.It was reported that first reported coil was attempted to be detached twice with the instant detacher.When switched to a separate detacher, detachment was still not possible.One manual detachment was made, and the coil still could not be detached.An attempt was made to collect the coil, but when it returned a little less than 2cm inside the catheter, the coil was detached.The coil was pushed using a guidewire and was placed in the aneurysm.The second reported coil was attempted to be detached three times with the instant detacher, but could not be detached.The patient had two aneurysms, so the coil was placed in the second aneurysm and was able to be successfully detached with the instant detacher.The procedure was completed. the patient did not experience any injury or health damage.The devices were prepared according to the instructions for use (ifu).

H3: the axium prime coil was returned without the introducer sheath.The actuator interface was found to be loose and not attached to the coupler tube.There appeared to be evidence of mechanical detachment using an instant detacher at this location.The axium prime pushwire was found to be kinked at ~6.9cm from proximal end and broken but retained by release wire at break indicator.This is indicative that a manual detachment was attempted at these locations.The coin was found not against the lumen stop.The shield coil was found intact with the implant coil already detached.The implant coil was not returned.No other anomalies were observed.Based on the analysis performed, the customer report of ¿premature detached from non-detachment¿ was confirmed as the axium pushwire was returned with the implant coil was already detached from the pusher.The cause for the delayed detachment could not be determined as all parts of the returned pushwire which could affect the detachment were found to be within specifications.There was no non-conformance to specifications identified that led to the reported issue.Since the implant coil and detach element were not returned any contributing factors could not be assessed.Kinks were found on the returned pusher.This can also be indicative of high tortuosity.It is possible the kinks found on the pushwire may have contributed to the non-detachment as it would increase resistance when the release wire and coin is being pulled away from the lumen stop.Based on the analysis findings, the customer report of ¿unable to detach¿ could not be confirmed.The event cause could not be determined.The returned instant detacher was used to successfully to detach in-house axium coils on the first attempt without any difficulty.There was no malfunction of the instant detacher or non-conformance to specification identified that led to the unable to detach issue.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.

H3: product analysis #704936818:equipment used: vis (m-78210), 203cm ruler (m-83361) document used: dwgs31053 rev.C as found condition (condition of returned device): two axium prime coils and an instant detacher were returned within a shipping box and within a plastic resealable biohazard bag.Visual inspection/damage location details: (pli-10) the axium prime coil was returned without the introducer sheath.The actuator interface was found to be loose and not attached to the coupler tube.There appeared to be evidence of mechanical detachment using an instant detacher at this location.The axium prime pushwire was found to be kinked at ~6.9cm from proximal end and broken but retained by release wire at break indicator.This is indicative that a manual detachment was attempted at these locations.The coin was found not against the lumen stop.The shield coil was found intact with the implant coil already detached.The implant coil was not returned.No other anomalies were observed.(pli-20) the axium prime coil was returned without the introducer sheath.The actuator interface was found to be loose and not attached to the coupler tube.There appeared to be evidence of mechanical detachment using an instant detacher at this location.The axium prime pushwire was found to be broken but retained by release wire at break indicator and kinked at ~111.0cm and kinked at ~157.9cm from proximal end.This is indicative that a manual detachment was attempted at these locations.The coin was found not against the lumen stop.The shield coil was found to be damaged (stretched) with the implant coil already detached.The implant coil was not returned.No other anomalies were observed.(pli-30) visual inspection of the assembled instant detacher (id) showed no defects.The surface around the bottom inner diameter of the instant detacher cap appeared to be clean.No other anomalies were observed.Testing/analysis (including sem reports): (pli-30) an in-house axium prime coil (model: apb-3-6-hx lot: a275717) was then selected for testing with the instant detacher.No difficulty was experienced inserting the pushwire into the instant detacher, and the load indicator was not visible when the pushwire was fully seated in the instant detacher cap.The implant coil was successfully detached on the first attempt without any difficulty.During evaluation, the instant detacher was taken apart to evaluate the components.All components appeared to be normal.The instant detacher cap inner diameter was measured to be 0.0145¿ with visual inspection system.The instant detacher was found to be within specifications.Conclusion: based on the analysis performed, the customer report of ¿premature detached from non-detachment¿ was confirmed as the axium pushwire was returned with the implant coil was already detached from the pusher.The cause for the delayed detachment could not be determined as all parts of the returned pushwire which could affect the detachment were found to be within specifications.There was no non-conformance to specifications identified that led to the reported issue.Since the implant coil and detach element were not returned any contributing factors could not be assessed.Kinks were found on the returned pusher.This can also be indicative of high tortuosity.It is possible the kinks found on the pushwire may have contributed to the non-detachment as it would increase resistance when the release wire and coin is being pulled away from the lumen stop.Based on the analysis findings, the customer report of ¿unable to detach¿ could not be confirmed.The event cause could not be determined.The returned instant detacher was used to s uccessfully to detach in-house axium coils on the first attempt without any difficulty.There was no malfunction of the instant detacher or non-conformance to specification identified that led to the unable to detach issue.(reyesr32 2022-05-04) medtronic is submitting this
