Additional Manufacturer Narrative
Product event summary: the lead was not returned for analysis, however, performance data collected from the device was received and analyzed.Analysis of the device memory indicated oversensing associated with the right ventricular lead.Analysis of the device memory also indicated the criteria for the right ventricular lead integrity alert were met, the impedance of the right ventricular defibrillation coil was beyond the expected upper range, the impedance of the right ventricular defibrillation coil had a spike, and the impedance of the superior vena cava defibrillation coil had a spike.Concomitant medical products: product id: dvbb1d4 icd; implanted: (b)(6) 2014, product id: 6996sq lead; implanted: (b)(6) 2021, product id: 5019 adaptor; implanted: (b)(6) 2021.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.
Event or Problem Description
It was reported that the right ventricular (rv) lead displayed high defibrillation impedance.In addition, there was also spike in rv coil and superior vena cava (svc) coil impedances.It was also noted that the patient is in hospice.The alerts for the right ventricular (rv) lead and therapies were programmed off.The lead remains in use.No patient complications have been reported as a result of this event.
