FDA says B. Braun Medical has notified customers recommending that certain microbore extension sets be removed from the market because their labels show incorrect information about the device’s filter. Specifically, the product label shows that the device contains an air-eliminating filter, but an [FDA alert](https://www.fda.gov/medical-devices/medical-device-recalls/early-alert-microbore-extension-set-issue-b-braun-medical-inc?utm%5Fmedium=email&utm%5Fsource=govdelivery) says the filter used on the extension sets does not feature an air vent and is not indicated for removing air.

“If during use there is air within the line or filter itself, the air can occlude the filter,” the alert says. “This could lead to a significant delay in therapy with significant impact on patient condition (e.g. with life-sustaining drugs). It is possible for air to escape the filter and enter the patient where embolization could occur. This could lead to patient harm up to and including permanent organ damage or death.”

The extension sets are single-use, disposable, add-on devices used for direct injection, intermittent infusion, continuous infusion or aspiration of fluids, medications, blood and blood products, the alert says.
