Patient injuries and deaths have occurred when different device delivery systems are mistakenly connected to each other. These errors are often facilitated by fittings called Luer connectors, which can allow different systems to be easily, but erroneously, connected. FDA has taken various actions to help educate healthcare professionals about these dangerous misconnections.
