First Claim
Patent Images
1. An endoprosthesis, in particular an intraluminal endoprosthesis, such as a stent, comprising:
- (a) a basic mesh; and
(b) a functional element having a first end attached to a carrier structure and having a second end and having a different material composition in at least a portion of the volume of the functional element in comparison with the material of the basic mesh,wherein the carrier structure is arranged on the basic mesh on the first essentially finger-shaped end and protrudes away from the basic mesh, andwherein the carrier structure has a plurality of branches in the area of the second end, andwherein the functional element is arranged on an area of the carrier structure that protrudes away from the base body and at least partially surrounds the area of the carrier structure.

Abstract
An endoprosthesis, in particular, an intraluminal endoprosthesis, e.g., a stent, having a basic mesh and a functional element attached to a carrier structure, the functional element having a different material composition than the material of the basic mesh in at least a portion of its volume. The carrier structure is arranged on the basic mesh in the first essentially finger-shaped end and protrudes away from the mesh essentially like a projection. The functional element is arranged on an area of the carrier structure protruding away from the base body and at least partially surrounds the area of the carrier structure.

16. An endoprosthesis, in particular an intraluminal endoprosthesis, such as a stent, comprising:
-
(a) a generally cylindrical shaped mesh structure made of a first material and having at least one finger-shaped first end and a second end, the second end having a plurality of fractal branches proximate thereto; (b) a carrier structure arranged on the basic mesh on the first essentially finger-shaped end and protruding away from the mesh structure; and
,(c) a functional element attached to the carrier structure and proximate to an area of the carrier structure that protrudes away from the mesh structure and at least partially surrounds the area of the carrier structure, at least a portion of the volume of the functional element being made of a material different than the first material.
