Abstract
Disclosed is a joining element, especially a suture material for surgical use. The joining element is composed of a core having a length that extends along a longitudinal direction, the core including a polymer material and an osmotically active substance distributed within the polymer material, wherein the core has a volume capable of swelling along a transverse direction that is perpendicular to the longitudinal direction upon exposure to a fluid; and, a diffusion-controlling extendable membrane that surrounds at least a portion of the length of the core, wherein the membrane is configured to regulate hydration of the core by the fluid, and is further configured to expand along the transverse direction in response to swelling of the core.
