Patent ID: 8585752

Claim:
A stent to be brought into contact with tissue in a living body through deformation at the time of indwelling the stent in the living body, the stent comprising: a plurality of annular bodies arrayed in an axial direction, each of the annular bodies being annularly-shaped from a linear constituent element, each of the annular bodies having a plurality of one-end-side bent sections which are bent sections at one axial end and a plurality of other-end-side bent sections which are bent sections at an opposite axial end; axially adjacent ones of the annular bodies being linked by link sections; and the stent including, as said link sections, at least three kinds of link sections selected from four kinds of link sections, the four kinds of link sections including: a vertex-vertex bent link section which links a vertex of one of the other-end-side bent sections of the one-end-side annular body of the axially adjacent bodies with a vertex of one of the one-end-side bent sections of the other-end-side annular body of the axially adjacent annular bodies and which has at least one one-end-side bent part and at least one other-end-side bent part; a central part-central part bent link section which links a central part of a linear portion interconnecting the one-end-side bent section and the other-end-side bent section of the one-end-side annular body of the axially adjacent annular bodies with a central part of a linear portion interconnecting the one-end-side bent section and the other-end-side bent section of the other-end-side annular body of the axially adjacent annular bodies and which has at least one one-end-side bent part and at least one other-end-side bent part; a central part-vertex bent link section which links the central part of the linear portion interconnecting the one-end-side bent section and the other-end-side bent section of the one-end-side annular body of the axially adjacent annular bodies with the vertex of one of the one-end-side bent sections of the other-end-side annular body of the axially adjacent annular bodies and which has at least one one-end-side bent part and at least one other-end-side bent part; and a vertex-central part bent link section which links the vertex of one of the other-end-side bent sections of the one-end-side annular body of the axially adjacent annular bodies with a central part of a linear portion interconnecting the one-end-side bent section and the other-end-side bent section of the other-end-side annular body of the axially adjacent annular bodies and which has at least one one-end-side bent part and at least one other-end-side bent part, the at least three kinds of the link sections including at least the vertex-vertex bent link section and the central part-central part bent link section, and the axially adjacent annular bodies being linked by at least two different kinds of the four link sections.
