Attachment means for attaching an implant to bone tissue

摘要

The attachment means has a shank 3 made from resorbable material which expands after implantation. The outer circumference of the shank 3 is formed in such a way that it can be placed in a hole 6 in the bone tissue 5 by exerting a force only in the longitudinal direction. Due to the expansion, the shank becomes secured in the hole 6 and may be of relatively small diameter, with the result that when the material breaks off a limited concentrated amount of material is released into the body. <IMAGE>
