Abstract
An intravascular medical device is prepared for shipping by being sealed within a sterile volume of a package. Prior to closing the package, an intravenous liquid solution is pumped into and through the medical device to displace all air bubbles. The liquid is pumped at sterilization temperatures corresponding to when the liquid has a low viscosity, but the liquid is chosen to have a relatively high viscosity at room temperatures corresponding to when the package is opened for use. The liquid solution remains adsorbed to the interior surfaces of the medical device at room temperature against a force of gravity. The strategy reduces the risk of air embolism when a medical device is put into use.
