STENT
First Claim
1. A stent comprising:
- a first cylindrical band body formed in a zigzag shape having first peaks and first valleys and having opposite ends that are integrally formed;
a second cylindrical band body having the same structure as the first cylindrical band body, the second cylindrical band body being disposed such that second valleys of the second cylindrical band body face the respective first peaks of the first cylindrical band body and second peaks of the second cylindrical band body face the respective first valleys of the first cylindrical band body with a plurality of predetermined gaps of a first row, thereby defining a plurality of rhombus spaces of the first row;
a third cylindrical band body having a same structure as the first cylindrical band body, the third cylindrical band body being disposed such that third valleys of the third cylindrical band body face the respective second peaks of the second cylindrical band body and third peaks of the second cylindrical band body face the respective second valleys of the second cylindrical band body with a plurality of predetermined gaps of a second row, thereby defining a plurality of rhombus spaces of the second row in a diagonal direction with respect to the first row;
at least one first link member that is provided in at least one rhombus spaces of the first row to interconnect the first and second band bodies; and
at least one second link member that is provided in at least one rhombus spaces of the second row to interconnect the second and third band bodies.

Abstract
A stent for securing a passageway of a body lumen in a constricted portion of the body lumen is disclosed. The stent includes a first cylindrical band body formed in a zigzag shape having a plurality of straight sections interconnected by first peaks and first valleys and having opposite ends that are integrally formed, a second cylindrical band body having a same structure as the first cylindrical band body, the second cylindrical band body being disposed such that second valleys of the second cylindrical band body face the respective first peaks of the first cylindrical band body and second peaks of the second cylindrical band body face the respective first valleys of the first cylindrical band body with a plurality of predetermined gaps of a first row, thereby defining a plurality of rhombus spaces of a first row, at least one first link member that is provided in at least one rhombus spaces of the first row to interconnect the first and second band bodies, at least one second link members that are provided in at least one rhombus spaces of the second row to interconnect the second and third band bodies.
