A coupling member for surgical purposes is provided. A core extending substantially along a longitudinal direction, the core comprising a polymeric material and an osmotically active material dispersed in the polymeric material, and at least a portion of the core along the longitudinal direction A sleeve that defines a longitudinal length between opposite ends of the sleeve and includes at least one thread, the at least one thread defining an angle that intersects the longitudinal direction. A coupling member, wherein the osmotically active substance has a variable distribution density in the polymer material, the variable distribution density changing in a radial direction relative to the longitudinal direction.
