摘要:
A stent is provided, which joins a plurality of stent components via a strut which, even when repeatedly bent over a long period of time, resists breaking. In particular, a stent is provided having a joining portion which integrally joins a stent main wire and a strut, the stent main wire and the strut being fitted into a restraining pipe in a non-joining portion of the stent main wire and the strut near the end of the joining portion. This construction restrains the relative movement of the stent main wire to the strut 4 is restrained and decreased, thus reducing fatigue.

It is an object of the present invention to provide a stent including a plurality of loop stents connected with one another using a plurality of loop struts and adapted to bend uniformly as a whole.A stent 1 has a connection part in which wire parts including a stent main wire 2 and a strut 4 are connected to each other through a junction pipe 7, wherein the strut 4 is larger in diameter than the stent main wire 2.

It is an object of the present invention to prevent a wire part including a stabilizer hook, a strut or the pulling-back member from separating from a connection part even when a force in a tensile direction is applied to a stent.A stent 1 having a connection part in which wire parts including a stent main wire 2, a strut 4 and a stabilizer hook 5 are connected to each other through a junction pipe 7, wherein a locking part which is locked to the junction pipe 7 is formed on the wire part which is inserted into the junction pipe 7.

In a stent which joins a plurality of stent components by a strut, even when the repeated bending acts on the stent for a long period, the breaking of the strut can be prevented.In a stent 1 having a joining portion 7 which integrally joins a stent main wire 2 and a strut 4, the stent main wire 2 and the strut 4 are fitted into a restraining pipe 8 in a non-joining portion of the stent main wire 2 and the strut 4 near the end of the joining portion 7. The relative movement of the stent main wire 2 and the strut 4 is restrained. The amount of movement of the strut 4 relative to the stent main wire 2 can be decreased to reduce fatigue.
摘要:
A stent has a stent main wire. The strut is disposed adjacent to the stent main wire and a junction pipe disposed around the stent main wire and strut so as to affix the stent main wire to the strut. A locking part is formed at an end of the strut to prevent the strut from sliding out of the junction pipe. The locking part comprises a folded back portion, wherein a distal most end of the folded back portion abuts with a distal most end of the junction pipe, a swelling portion, wherein a distal most end of the swelling portion is abutting a distal most end of the junction pipe, or a bent portion, wherein a distal most end of the bent portion is abutting with a distal most end of the junction pipe.

A stent (1) formed in the shape of a generally tubular body which has a spring function with which the tubular body is diameter-contractible toward the central axis (C) of the tubular body and which is expandable to the initial diameter after contraction, the stent being loaded into a sheath and being to be delivered to a diseased part to be treated, wherein the stent (1) maintains a configuration curved along the longitudinal direction of the stent when not inserted in the sheath, and (B) when the stent (1) is inserted into the sheath, the stent (1) is contracted toward the central axis (C) of the stent (1) and is elongated in the form of a generally straight line along the longitudinal direction of the stent (1), whereby the stent (1) is loaded into the sheath in the form of a substantially straight line, and the stent can remarkably improve safety and conformity during delivery in the artery, and the like.
摘要:
A stent formed in a shape of a generally tubular body having a central axis. The stent has a spring function with which the tubular body is diameter-contractible toward the central axis, and the tubular body is expandable to an initial diameter after contraction. The stent maintains a configuration curved along a longitudinal direction of the stent when the stent is not inserted in a sheath. The stent is elongated in a form of a generally straight line along the longitudinal direction when the stent is inserted into the sheath. The stent, being housed in a sheath in the form of a generally straight line, is inserted into a diseased part together with the sheath, is released from the sheath, and radially expands, outwardly after release, to restore and maintain a configuration curved along the longitudinal direction of the stent.

A sheet post process device with a stapler mechanism includes a conveying path configured to convey a sheet on which an image is formed to the stapler mechanism; a first sensor disposed along the conveying path and configured to detect a moving position of the sheet; and a tray in which the sheets are stacked to undergo a stapling process; and a rotary cam having a spiral shape disposed at a conveying path outlet through which the sheet is ejected from the conveying path to the tray. When the sheet passes through the conveying path outlet, the cam rotates and comes into contact with the sheet to move the sheet to the tray.
