You can call this one "mailing in extra protection". A medical company has developed an anti-bacterial "envelope" for implantable cardiac defibrillators. The mesh envelope contains anti-microbial agents that are released into the body to help protect against infection at the surgical site. The new technology also helps stabilize the device in the body, and makes it easier to replace it in the future. The envelope has been approved by FDA and is available in select US hospitals.
