摘要： A stent manufactured for treating internal tubular organs, typically for treating a blood vessel, in which the stent has a sufficient diametral shrinkage ability and an ability for returning back to the original diameter thereof. A zigzag shape-memorized stent A is manufactured by performing shape memorization where a wire 1 is fixed in a zigzag bent manner in which the wire is made from a shape-memorizing Ni—Ti alloy not having been subject to shape-memorization of any sort. A stent A being shape-memorized with a zigzag shape as well as a cylindrical shape could be manufactured by performing shape-memorization process in which a stent having been shape-memorized into a zigzag shape with the end portions thereof being connected by overlapping with each other, is attached to a cylindrical jig.

摘要： The problem that a metal wire joined integrally to a hole formed in a proximal end face of a medical suture needle is susceptible to bending damage is reduced.A suture needle A has a blind hole 5 which is formed in a proximal end face 3, inserts the end of a wire 10 thereinto, and joins the wire 10 thereto by caulking, and a counterbore 6 which is formed on the proximal end face 3 side of the blind hole 5 and has a dimension D at least in the proximal end face 3 larger than a dimension d of the blind hole 5 and a depth L smaller than a depth of a caulked portion with respect to the blind hole 5. A suture needle with wire inserts the end of the wire 10 into the blind hole 5 to caulk the outer circumference of the suture needle corresponding to the blind hole 5, thereby integrally joins the wire 10 thereto.

摘要： 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 blood vessel knife allows a doctor to easily see a knife main body when holding it for surgical operation. In a blood vessel knife having a cutter holder at a tip portion of a rod-shaped grip, and a knife main body attached to a tip of the cutter holder, at least one of a first bent portion 2a formed at an end of the grip 2 and a second bent portion 3a formed on the cutter holder 3 is provided; the cutter holder 3 can be detachably engaged with the tip portion from either an inside or outside thereof; and an angle between the grip 2 and the knife main body is changeable whether the cutter holder is engaged from the inside or the outside of the tip portion. When gripping the blood vessel knife 1, doctors can easily see the knife main body 4 due to the second bent portion 3a, and the knife main body 4 diagonally penetrates a blood vessel 15 to prevent the knife main body 4 from penetrating a lower blood vessel wall 15b.

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.

摘要： A polysilicon film and the like are patterned to form n-diffusion layers on a silicon substrate. Subsequently, an outer edge of an Al2O3 film is made retreat to be smaller than that of a gate electrode by performing isotropic etching of the Al2O3 film, using a solution of sulfuric acid with hydrogen peroxide. A silicon oxide film, a silicon nitride film, the polysilicon film and the like are hardly removed although the solution of sulfuric acid with hydrogen peroxide exhibits higher etching rate to the Al2O3 film, enabling almost exclusive etching of the Al2O3 film at a high selectivity ratio. Subsequently, another polysilicon film is formed so as to fill spaces formed after the retreat of the Al2O3 film under the silicon oxide film. Subsequently, a sidewall insulating film is formed by remaining portions of the later polysilicon film in the spaces by performing RIE, oxidation, or the like of the later polysilicon film.
