Event Description

Information was received from multiple sources (manufacturer representative, healthcare provider) regarding a patient who was implanted with an implantable neurostimulator (ins) for unknown indications for use.It was reported that the leads were connected to an implantable neurostimulator (ins) with normal battery depletion after over 10 years.The leads were connected to the ins via one 10 cm extension each.The insulation of both leads was broken or pulled down right after the proximal connector rings. in order to unscrew the extensions, the protective cap was removed.After unscrewing the leads from the extension, the damage to the insulation was noticed. the leads were connected to a an extension and impedances were measured with values in normal to slightly higher range (1500-1900 ohms).The leads could not be inserted into the extension completely without being afraid to not being able to remove it again.The healthcare professional (hcp) was afraid that the lead wires would break when the lead is being removed from the extension. hcp decided to explant both leads, as they were afraid that, when trying to connect them to a new ins and the impedances were not good, then they would not be able to disconnect the lead from the ins connector again.It was unknown whether the lead insulation was broken prior to the ins replacement surgery already.It could potentially have been damaged during the attempt to disconnect the leads from the already implanted extension. a new lead was implanted instead of the two explanted leads. issue resolved. .

Manufacturer Narrative

H3: analysis of the returned lead model# 3889-98 identified that the conductor 0 was broken at the connector 1.5cm from proximal end of the lead; consistent with overstress damage.Analysis identified that the body of the lead was stretched.Analysis identified that the butt joint of the outer insulation was separated at the proximal end of the lead.Analysis of the returned lead model# 3889-98 identified that the butt joint of the outer insulation was separated at the proximal end of the lead.Analysis identified that the body of the lead was stretched.Analysis identified that the insulation was torn under the electrode 3 at the distal end of the lead.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.
