Product analysis: as found condition: the phenom 21 catheter was returned for analysis within a shipping box; within a plastic bio-pouch; and within an opened phenom 21 catheter outer carton.Visual inspection/damage location details: upon visual inspection, no damages or irregularities were found with the phenom 21 catheter hub.The phenom 21 catheter body was found to be flattened from ~12.5cm to the distal tip.The distal tip was appeared to be damaged/ deformed.No other anomalies were observed.Testing/analysis: the phenom 21 total and usable lengths were measured to be within specification.The phenom 21 catheter was flushed, water exited from the distal tip.The phenom 21 catheter was then tested with an in-house 0.021¿ mandrel.The in-house mandrel was inserted into the phenom 21 hub and pass through the catheter lumen without any issues.Conclusion: based on the device analysis and the reported information, the customer¿s report of ¿marker band dislodged¿ was confirmed as the distal tip was damaged/deformed.However, the phenom 21 could not be confirmed to have catheter stretch during removal or catheter entrapment/difficult removal.The phenom 21 catheter did not appear to be stretched.Possible causes for ¿catheter stretch during removal¿ include use of incompatible devices, patient vessel tortuosity, catheter entrapment, user operational context if user advances or retrieves intraluminal device against resistance and excessive force used in procedure (pushing or pulling).It is likely that patient tortuous anatomy during delivery may have contributed to the reported issues.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.
