Constructive arrangement introduced in endoprosthesis

A constructive arrangement introduced in endoprosthesis, consisting of:

• at least one metallic structure (1) formed by a single segment of wire arranged in a peak-valley configuration and in a helical arrangement;
• an outer coating layer made up of an outer laminate (21) and an inner laminate (22), said outer laminate (21) being made of a self-lubricating polymer and said inner laminate (22) being made of a hot-meltable polymer;
• and
• an inner coating layer made up of an outer laminate (31) and an inner laminate (32), said outer laminate (31) being made of a self-lubricating polymer and said inner laminate (32) being made of a hot-meltable polymer;
• the constructive arrangement introduced in endoprosthesis comprises:
• at least a part of said metallic structure (1) is arranged between the result of the hot-melting between the inner laminate (22) of the outer coating layer and the inner laminate (32) of the inner coating layer;
• the constructive arrangement introduced in endoprosthesis further consists of at least one capillary structure (4) axially arranged along an axial segment of the endoprosthesis;
• and
• said capillary structure (4) is axially arranged between the result of the hot-melting between the inner laminate (22) of the outer coating layer and the inner laminate (32) of the inner coating laver.
