Manufacturer Narrative

H3: the echelon-10 micro catheter was returned for analysis.The guide catheter used during the event was not returned for analysis.No damages or irregularities were found with the echelon-10 micro catheter hub.No damages or irregularities were found with the micro catheter body.The distal tip and marker band was found separated and not returned for analysis.The edge of the break was found jagged.The echelon-10 micro catheter total length was measured to be ~152.8cm and the usable length was measured to be ~145.0cm, which is still within specification (specification: total (ref) = 152cm, usable = 144.0cm ± 1.5cm).Based on the device analysis and reported information, the customer¿s report of ¿marker band dislodged¿ was confirmed.Possible causes are tensile failure, user advances/retrieves against resistance, patient vessel tortuosity, kink/damage in guide catheter, or catheter tip shaping.As the guide catheter used in the event was not returned for analysis, any contribution of the guide catheter towards the marker band and distal tip detachment could not be determined.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.
