STENTS HAVING RADIOPAQUE MESH

摘要

A stent including a mesh made of strands. The mesh has at least one radiopaque strand and at least one non-radiopaque strand, and the at least one radiopaque strand and the at least one non-radiopaque strand each have different diameters. Each strand has an index of wire stiffness EI, where EI is the mathematical product of the Young's modulus (E) and the second moment of area (I). The EI of all strands in the mesh is no more than five times the EI of the strand having the smallest EI of any of the strands.

1. A method, comprising:
expanding, against a wall of a vessel in a body of a patient, a stent comprising a mesh, the mesh comprising at least one radiopaque strand and at least one non-radiopaque strand, the at least one radiopaque strand and the at least one non-radiopaque strand each having different cross-sectional dimensions, and wherein each of the strands has an index of wire stiffness EI, where EI is the mathematical product of the Young's modulus (E) and the second moment of area (I), and wherein the EI of each non-radiopaque strand is no more than five times the EI of a strand having the smallest EI of any of the strands.
