A method for filling a hollow space in an autoclavable medical instrument with an adhesive containing a filler has the steps of providing an adhesive with a low viscosity allowing the adhesive to enter into a hollow space in a medical instrument, providing a filler of solid particles within said low viscosity adhesive, density of said solid particles differ from a density of said low viscosity adhesive, filling that hollow space in said medical instrument with that low viscosity adhesive containing said solid particles, allowing said particles a period of time for crowding together into a minimum of space, and curing said adhesive after said period of time.
