Luminal endoprosthesis
Flow-regulating luminal endoprosthesis ( 30 ) comprising a first sections and a second section characterised in that at an end ( 35 ) of the endoprosthesis, the second section is turned over on the inside or the outside of the first section in such a way as to form an endoprosthesis ( 30 ) comprising two substantially coaxial sections ( 31, 32 ) and a turnover part ( 33 ) that joins the two sections ( 31, 32 ), with the turnover part ( 33 ) being located at an end ( 35 ) of the endoprosthesis ( 30 ) and method pour manufacturing the endoprosthesis ( 30 ).
1. A flow-regulating luminal endoprosthesis ( 30 ) comprising at least one first section and one second section, with each one of the sections comprising a braided meshing, wherein at an end ( 35 ) of the endoprosthesis, one of the sections is turned over with respect to the other section in such a way as to for the endoprosthesis ( 30 ) comprising two coaxial sections ( 31 , 32 ) separated by 0.5 mm to 4 mm and a turnover part ( 33 ) that joins the two sections ( 31 , 32 ) and located at the end ( 35 ) of the endoprosthesis ( 30 ), wherein the coaxial sections ( 31 , 32 ) comprise a material of which the elastic modulus is between 0.050 N/m 2 and 1 N/m 2 .
2. The endoprosthesis as claimed in claim 1 , wherein the meshing of the first and the second sections has a surface with a porosity of 60 to 75%.
3. The endoprosthesis as claimed in claim 1 , wherein the meshing of the first and the second sections is such that a superposition of the first and second sections is permeable to blood.
4. The endoprosthesis as claimed in claim 1 , wherein meshes forming the meshing of the first and the second sections have sides between 1 mm and 2 mm.
