Manufacturer Narrative

Conclusion: based on test results, from the blood lab of other returned devices with similar cracks this is a representative failure mechanism of poor gas transfer.Damage to the gas cap can prevent appropriate gas flow which impacts gas transfer.The type of damage observed is typically associated with a physical shock encountered during shipping and/or handling.Throughout the assembly process each device is visually inspected, manufacturing controls are in place to ensure that product meets specification prior to the release from the manufacturing facility.Within medtronic control, no damage reports were received through sterilization or distribution centers.The dhr for the device was reviewed and did not identify any anomalies or deviations in the manufacturing process which would cause or contribute to the reported event.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.
