Abstract: A medical device, an elastically deformable functional part for a medical device, and a method for sterilizing and/or for establishing sterilization resistance of a medical device or an elastically deformable functional part. The elastically deformable functional part has an openable slit arrangement. The slit arrangement widens or opens upon elastic deformation of the elastically deformable functional part and recloses upon cessation of the elastic deformation. The slit arrangement has slit wall faces with a separating agent. The separating agent can be a solid.

Abstract: A medical device, an elastically deformable functional part for a medical device, and a method for sterilizing and/or for establishing sterilization resistance of a medical device or an elastically deformable functional part. The elastically deformable functional part has an openable slit arrangement that widens or opens upon elastic deformation of the elastically deformable functional part and recloses upon cessation of the elastic deformation. The slit wall faces of the slit arrangement are coated with a composition that includes a silicone oil and a thickener.

Abstract: A method of producing an elastically deformable functional part for a medical device, devices for such methods, and a medical device having such a functional part. The functional part has an openable slit arrangement that widens or opens upon elastic deformation of the functional part and closes again in the absence of the deformation.
