1. A catheter assembly comprising:
a catheter;
a housing having an internal cavity in which the catheter is housed, the housing comprising a hermetic seal for preserving the sterility of the internal cavity prior to use;
a wetting agent chamber located in the internal cavity; and,
wherein the catheter assembly is configured to deploy the catheter in a first step and a subsequent second step,
wherein the first step comprises breaking the hermetic seal and priming the wetting agent chamber to put the catheter assembly into a leak-resistant primed configuration in which the catheter is configured to be wettable with the wetting agent; and,
the second step comprises removing the catheter from the housing; and
a priming mechanism, the priming mechanism configured to carry out the first step with a single user action, wherein the priming mechanism comprises a movable insert which partially defines the wetting agent chamber, the movable insert being movable between a sealed configuration and a primed configuration during the first step, and wherein the movable insert is provided by the catheter.
