A fixation device comprises an elongated element extending along a central axis having a total length L and including a proximal section formed of a material that is substantially non absorbent for electromagnetic radiation within a preselected wavelength range and a distal section formed of a material that is substantially non absorbent for electromagnetic radiation within the preselected wavelength range in combination with a middle section axially arranged between the proximal and distal sections the middle section formed of a material that is substantially absorbent for electromagnetic radiation in the preselected wavelength range.
