Abstract: In an intervertebral implant having an upper and a lower supporting surface for abutment with adjacent vertebral bodies, having a concave dorsal longitudinal side, a ventral longitudinal side lying opposite the latter, having a rounded contour at the two end faces connecting the longitudinal sides and having at least one hole extending through the implant from the upper to the lower supporting surface, in order to facilitate the introduction of bone material after insertion of the intervertebral implant into an intervertebral space it is proposed that in the region of the middle portion of the ventral longitudinal side at least one introduction channel for bone material, which extends through the implant, exits from the implant.

Abstract: In order to prevent undesirable deformations in a plate-shaped filter holder for a sterilising container, including a peripheral outer pressure rim, a central pressure region, a mounting device for fixing the filter holder on the sterilising container, and including webs between the outer pressure rim and the central pressure region which leave open breakthroughs therebetween, it is proposed that the webs extend at least partially in a direction which comprises a component in the peripheral direction.
