Abstract: A stent delivery device for delivering a self-expanding stent comprises an inner sheath including a proximal end portion and a distal end portion, a stent stopper including a stopper main body that is circumferentially disposed over at least a portion of the inner sheath at the proximal end portion, and at least one projection extending radially outward from the stopper main body for releasably engaging a portion of the self-expanding stent, and an outer sheath slidably disposed over the inner sheath and the stent stopper. The at least one projection includes a distal end surface and a proximal end surface, and the proximal end surface includes a recess extending into a body of the projection toward the distal end surface.

Abstract: For the purpose of firmly fusing a low-cost osteosynthetic implant having high osteoconductivity with a bone in a short period of time after implanting without having to perform treatment to restore surface hydrophilicity, a osteosynthetic implant is provided with a substrate that is formed of magnesium or a magnesium alloy and a porous anodic oxide coating that is formed on a surface of the substrate, wherein the anodic oxide coating has an outer surface that, due to the sizes and distribution of pores that are formed when generating the anodic oxide coating by means of anodic oxidation treatment, structurally prevents water from entering the pores while maintaining the hydrophilicity thereof.

Abstract: The possibility of performing a bending process again on an area that has already been bent once is reduced. Provided is a bending device including two receiving sections disposed with a distance therebetween; a pressing section that presses a plate-like workpiece, which is supported in a bridged manner between the receiving sections, into a space between the receiving sections; an operable section that applies an external force for causing the pressing section to generate a pressing force; and a marker retaining section that is attached to at least one of the pressing section and the receiving section side and that retains a marker to be adhered to a pressed area of whichever one of surfaces of the workpiece by means of the pressing force.

Abstract: It is possible to maintain a base material made of magnesium or a magnesium alloy so as to prevent rapid degradation over a predetermined period after implanting. Provided is a biological implant including a ceramic membrane provided on a surface of a base material made of magnesium or a magnesium alloy, wherein the total content of a metal element contained in the ceramic membrane, which has a standard electrode potential equal to or greater than −2.35 V and equal to or less than 0 V, is set to be equal to or less than a value at which the base material can keep a desired mechanical strength over a healing period of an implant site in biological tissue.

Abstract: The stent having self-expandability, the stent including: a body part formed in a tubular shape by a wire; and a first locking part and a second locking part protruding outward in a radial direction of the body part and formed by the wire. A first angle formed by a protrusion direction of the first locking part and an axial direction of the body part is different from a second angle formed by a protrusion direction of the second locking part and the axial direction.

Abstract: Provided is an osteosynthetic implant including a base material composed of magnesium or a magnesium alloy and a ceramic membrane containing magnesium and formed on a surface of the base material. The ceramic membrane includes a porous lower membrane layer disposed in a region adjacent to the base material and an upper membrane layer covering the lower membrane layer and serving as an outermost layer. The upper membrane layer is denser than the lower membrane layer.
