A process for setting an angioplasty stent (S) on a corresponding insertion element (C), in which said angioplasty stent is subjected to an action of radial contraction, envisages that the stent (S) will be subjected to the action of radial contraction before being placed on said insertion element (C). Preferably, the action of radial contraction is carried out in such a way as to bestow on the stent (S) a given diametral dimension (d2) at least marginally smaller than the homologous diametral dimension of the insertion element (C), which typically consists of a balloon catheter. After the stent (S) has been set on the insertion element (C), in the structure of the stent there remain residual states of constraint which act in the direction of securing the stent in the condition of coupling to the insertion element (C). <IMAGE> |
