Product analysis: ¿ as found condition: the marathon catheter was returned for analysis within a shipping box; within a plastic bio-pouch; and within an opened marathon outer carton and inner pouch.The (asahi) chikai-10 guidewire 0.010¿ guidewire used in the event was not returned.The (asahi) chikai-10 guidewire 0.010¿ guidewire has a labeled proximal od (outer diameter) of 0.010¿ and distal od of 0.010¿, as per an online source.Per the marathon ifu (instructions for use), the marathon is not compatible with non-hydrophilically coated guidewires greater than 0.010¿ in diameter.Therefore, the (asahi) chikai-10 guidewire 0.010¿ guidewire was found compatible for use with the marathon micro catheter.Visual inspection/damage location details: the marathon total, usable and distal floppy segment lengths were measured to be within specification.No damages or irregularities were found with the marathon hub.No bends or kinks were found with the marathon catheter body; however, the catheter body was found punctured at ~0.5cm from the distal tip.No damages or irregularities were found with the marathon distal marker/tip.No other anomalies were observed.Testing/analysis: n/a conclusion: based on the device analysis and reported information, the customer¿s report of ¿catheter puncture¿ was confirmed.Catheter puncture can occur if the catheter becomes kinked or prolapsed during insertion of the guidewire.In addition, it is possible the patient¿s ¿moderate tortuous¿ anatomy contributed to the event.However, the cause for the puncture 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.
