摘要:
1. A medical implant (10; 20) for expanding and maintaining the vessel of the human body from its inner side (= "stent"), which is configured to be inserted into the vessel of the human body in a compressed state, preferably minimally invasive, with the possibility of positioning there, and the possibility of translation into the open state, while the implant (10; 20) is made in the form of a tube of elongated ribs (11, 11 ', 11 ”; 21, 21', 21” forming the wall of the implant (10; 20)), while ribs (11, 11 ', 11 "; 21, 21', 21"), at least in sections, made with the possibility of plastic deformation so that the implant (10; 20) in the open state remains stably expanded in the radial direction across the longitudinal axis of the ribs (11, 11 ', 11 ”; 21, 21', 21”), and at least one of ribs (11; 21) has a stretchable element (12, 12 '; 22; 32a, 32b, 32c), which forms a portion of the rib inside this rib (11; 21), on which the stretchable element (12, 12'; 22; 32a 32b, 32c) in a compressed state partially extends geometrically across the longitudinal axis of the rib (11; 21), while the passage of the stretchable element (12, 12 '; 22; 32a, 32b, 32c) relative to this longitudinal axis has several changes in direction, characterized in that the material, thickness and width of the ribs of the stretchable element (12, 12'; 22 ; 32a, 32b, 32c) are selected so that as a result of the application of a radial force in the form of an implant tube (10; 20), the stretchable element (12, 12 '; 22; 32a, 32b, 32c) due to plastic elongation can be is brought into a stably open state in which the forming tensile element (12, 12 '; 22; 32a, 32b, 32c) the ribs have a greater geometric tension across the longitudinal axis and a smaller1. Медицинский имплантат (10; 20) для расширения и поддержания сосуда тела человека с его внутренней стороны (= «стент»), который выполнен с возможностью вставления в сосуд тела человека в сжатом состоянии, предпочтительно минимально инвазивно, с возможност
