Abstract
A stent ( ), made of a shape-memory alloy and inserted into a stenosed vessel ( ), and a stent foundation device for inserting such a stent ( ) into a desired part ( ) of the stenosed vessel ( ) are disclosed. The stent ( ) consists of a net-structural hollow cylindrical body ( ) made by knitting one longitudinal superelastic shape-memory alloy wire while repeatedly crossing the wire at various points so as to form a plurality of diamond-shape meshes ( ). The stent foundation device consists of an actuation steel core ( ), a moveable tube ( ) and an insert tube ( ), which are received within an outside hollow tube ( ) while being axially movable within the outside tube. ( ). In the above device, an insert tip ( ) is connected to the front end of the insert tube ( ). The insert tip ( ) has a step ( ) forming a fitting end, at which the insert tip ( ) is partially fitted into the front end of the outside tube ( ) and is connected to the front end of the insert tube ( ). A thread ( ) is fixed at one end thereof to the insert tube ( ) at a position spaced apart from the step ( ) of the insert tip ( ) by a distance. The above thread ( ) holds the stent ( ) on the insert tube ( ) within the outside tube ( ).
