Abstract
A method of making a ready-to-use catheter assembly and a ready-to-use catheter are provided, which avoids any degradation of the catheter during sterilization. The method comprises: placing a catheter with a hydrophilic coating and a wetting fluid in a catheter package made of low moisture transmission material while the package is in a first condition wherein an insertable length of the hydrophilic coating of the catheter is not in contact with the wetting fluid, sterilizing the catheter package with the catheter and the wetting fluid by radiation sterilization while the catheter package is kept in a condition in which the insertable length is not in contact with the wetting fluid, transferring the catheter package with the catheter and the wetting fluid into a second condition, bringing the wetting fluid into contact with at least the insertable length and activating the insertable length via gravity and/or via inertia.
