The sterilized medical device assembly is a medical device (1) having a hydrophilic surface on at least a part of the medical device, such as a hydrophilic urinary catheter, and a package (3) forming a closed compartment for accommodating the medical device. And. The medical device is placed in an activated state in the packaging in which the hydrophilic surface is moistened with the wetting fluid (2). In addition, a small amount of wetting liquid is freely placed within the sealed compartment of the package and comes into direct contact with the hydrophilic surface of the medical device. The volume of the wetting liquid corresponds to 0.01% to 10% of the volume of the closed compartment. Medical device assemblies have been vapor sterilized and found that very small amounts of free liquid are very effective in ensuring reliable and effective vapor sterilization. [Selection diagram] Fig. 1滅菌済み医療器具組立体は、親水性導尿カテーテルなどの、医療器具の少なくとも一部に親水性表面を有する医療器具（１）と、医療器具を収容する密閉区画を形成する包装体（３）とを備える。医療器具は、親水性表面が湿潤流体（２）で湿潤された包装体内に活性化状態で配置される。加えて、少量の湿潤液は、包装体の密閉区画内に自由に配置されて、医療器具の親水性表面と直接接触する。湿潤液の体積は、密閉区画の容積の０．０１％～１０％に相当する。医療器具組立体は蒸気滅菌され、信頼性が高く有効な蒸気滅菌を確実に行うのに極少量の自由液体が非常に有効であることが分かった。【選択図】図１
