US Patent 8011505 Vapor hydrated collapsible sleeve hydrophilic catheter package

A vapor hydrated packaged catheter assembly includes a gas impermeable package housing a catheter within a catheter-receiving cavity. The catheter assembly has a hydrophilic coating on at least a portion of the outer surface of a catheter tube which may be surrounded by a sleeve. The catheter assembly is disposed within the catheter receiving cavity of the package with a vapor donating liquid provided as a source of vapor to activate the hydrophilic coating. The amount of vapor donating liquid is less than the amount that would otherwise be sufficient to cause a spill hazard. The catheter assembly is ready to use due to exposure of the hydrophilic coating to a vapor produced by the vapor donating liquid.
