The present invention relates to a temporary stent made from biodegradable shape memory polymeric (SMP material) material for use in the non-vascular or vascular field. The SMP material comprises a covalent polymer network or an interpenetrating polymer network. The stent may be implanted in compressed form by means of minimal invasive surgery and takes its desired size at the location of use caused by the shape memory effect. The stent gradually resolves caused by biological degradation which makes further surgery for removing the stent dispensable. The invention also relates to a method for manufacturing the stent and a kit comprising the stent and a temperature-controlled balloon catheter with an optical fibre.

L'invention concerne une endoprothèse biodégradable, comprenant un matériau polymérique à mémoire de forme et destinée à être mise en oeuvre dans le domaine non vasculaire ou vasculaire.
