Title: DEVICE FOR FIXING A PROSTHESIS TO A BONE
Abstract:
A device (11) for fixing a prosthesis to a bone (24) has a first member (12) adapted for connecting to the prosthesis and has a second member (13) adapted for anchoring the device (11) in the bone (24). At least a substantial part of the second member (13) is made of a shape memory material which is capable of changing its shape between a first and a second state as a result of an appropriate temperature range. The second member (13) consists of a plurality of discrete wall members (18) having each one end (19) integral with said first member (12) and another, free end (20). In the said first state the wall member (18) is defined together a shape resembling that of a prismatic or cylindrical tube, and in said second shape, the free ends (20) of the wall members (18) become more distanced from one another, whereby the fixation device (11) becomes anchored in a bone (24).
