The notification instructs the customer to pass the information onto all other users, as well as any downstream customers if it was further distributed. The notification also informs the customer their response is required using the enclosed form and the return addressed envelope. The response form asks, in part, if they are interested in accepting the fix. If they decline the fix, they are asked to provide the reason why. The response was required no later than April 18, 2016. Nonresponders were issued a second letter dated July 11, 2016, asking for a response by August 8, 2016. The letter and response form contained the same information as the first letter. If the second letter results in additional unresponsive customers, a call campaign will be managed by Customer Support and documented via SalesForce. Three call attempts will made before closing the case. The recalling firm reported emails will be tracked for delivery confirmation. For further questions please call ( 877) 741-5369.

About this record

Sourced from the FDA device recall database and the FDA enforcement reports, both ingested from openFDA. The recall record supplies the product, the reason and the product code; the enforcement report supplies the classification. The two datasets are exported by FDA on different days, and the date above is the older of the two, so nothing on this page is newer than it says.

MDM adds the root cause tag, derived from FDA’s own root cause text, and the cross-links to the product code, the clearances named on the record and MDM coverage. Where a recall has not been joined to an enforcement report, no classification is shown.
