Title: METHOD FOR PRODUCING AN EXPANSIBLE ENDOPROSTHESIS STRUCTURE FOR THE TREATMENT OF VASCULAR DISEASES, AND RESULTING IMPROVED ENDOPROSTHESIS STRUCTURE
Abstract:
The invention relates to a method for producing an expansible endoprosthesis structure for the treatment of vascular diseases, and to the resulting improved endoprosthesis structure, and represents an inventive solution in the medical field, being particularly useful for the treatment of vascular diseases, especially specific pathologies such as aneurysms and aorta dissections, differing from other solutions in expansible endoprosthesis structures (A), (B), (C) or (D) in that it is designed as a mesh composed of a plurality of sections (s1), ..., (Sn-1), (Sn), which, once closed, forming vertices (v1), (v2), (v3), ... (Vn-1), (Vn) and then circles, exhibit complete freedom of movement between the interlocking vertices around the entire circumference of the plurality of connections (v) defined by the interlocking vertices (v1), (v2), (v3), ..., (vn) between adjacent sections (Sn-1) and (Sn). Moreover, this structure has outstanding fatigue resistance and as a result a long service life, since each section (Sn) is formed by a single thread (1a) which can be optionally interlaced (1a), the structure being bound-off (f) using the end portions (1b) and (1c) of the single thread (1a).
