Event Description

It was reported that during the implant procedure, the guidewire got stuck inside of the left ventricular (lv) lead.It was noted that at the end of lead placement, the wire became stuck and it was impossible to remove it.The lead was removed with the guidewire still in it.The physician tried to remove the guidewire from the lead outside of the patient and the guidewire broke inside of the lead.It was suspected that a knot appeared at the end of the guidewire.The lead was not used, and another lead was implanted.No patient complications have been reported as a result of this event.

Manufacturer Narrative

Product event summary: the full lead was returned and analyzed.Analysis indicated the distal conductor of the lead was obstructed due to a guidewire fragment stuck in the lumen.The guidewire was broken.The guidewire was unraveled.The distal conductor was extrinsically distorted due to kinking/buckling.There was guidewire coating on the distal conductor of the lead, and it was obstructed.The distal low voltage electrode of the lead was covered in body tissue/fibrotic growth.Visual analysis of the lead indicated damage at implant.The analyst noted the competitor guidewire's hydrophilic coating adhered to the coil filars causing the guidewire to stick in the lead lumen.As a result, the coil filars became distorted causing the guidewire to break when trying to pull the guidewire out 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.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.
