PROVIDED IS A STENT (10, 46) OF A NOVEL STRUCTURE WITH WHICH DEFLECTION OF A LINE-SHAPED BODY (14) DURING EXPANSION IS PREVENTED AND A SUBSTANTIALLY UNIFORM EXPANSION IS ACHIEVED OVER AN ENTIRE LENGTH THEREOF, AND WITH WHICH, AFTER IMPLANTATION, STENT (10, 46) FRACTURE AND DAMAGE OF BODY TISSUE CAN BE PREVENTED BY THE STENT (10, 46) EXHIBITING A SUPERIOR PLIABILITY AND CONFORMABILITY TO A SHAPE OF A SOMATIC LUMEN. A STENT (10, 46) HAVING A CYLINDRICAL PERIPHERAL WALL (12) FORMED WITH A LINE-SHAPED BODY (14) THAT EXTENDS IN A HELICAL FORM IN A CIRCUMFERENTIAL DIRECTION WHILE RECIPROCATING IN AN AXIAL DIRECTION AT A GIVEN AMPLITUDE. IN THE STENT (10, 46), CONNECTING PARTS (22, 42) ARE FORMED TO LINK PORTIONS OF THE LINE-SHAPED BODY (14) THAT ARE ADJACENT IN THE AXIAL DIRECTION, AND A FRIABLE PART (24, 44) IS PROVIDED TO RUPTURE ITSELF BY BEING IMPLANTED IN THE SOMATIC LUMEN AND RELEASE A LINK MADE BY THE CONNECTING PARTS (22, 42). THE MOST SUITABLE DRAWING: FIG. 1.
