Abstract: The purpose of the present invention is to provide a resin composition for manufacturing a medical storage container that has improved oxygen permeability and that tends not to have excessively lower transparency. To this end, the present invention pertains to a resin composition for manufacturing a medical storage container, the composition including polyethylene (a) and polymethylpentene (b). The resin composition contains, as polyethylene (a), a first polyethylene (a-1), which is a main component of the polyethylene (a), and a second polyethylene (a-2) having a lower density than the first polyethylene.

Abstract: An indwelling device 1 is provided with: a sheath 20 that is capable of housing a stent graft 10; and a long shaft 30 that is configured to be capable of advancing or retreating inside the sheath along the axial direction. The shaft has a fixing tool 34 and a hollow tube 35 that are respectively engaged with a connection part 14 and a blood vessel wall fixing part 15 of the stent graft to restrict movement of an opening end 11a of the stent graft in the radial direction. The indwelling device is configured to be capable of releasing engagement between the connection part and the fixing tool and engagement between the blood vessel wall fixing part and the hollow tube independently of each other by displacing the shaft with respect to the stent graft in the axial direction.

Abstract: The present invention eliminates the need for highly accurate alignment with a branched tubular tissue when implanting a stent graft. A stent graft 30 comprises: a framework section 31; and a tubular graft section 40. A side surface opening 42 that passes through to the lumen of the graft section is provided in one section of a tube wall 41 of the graft section. In the framework section, among the six frame bodies, the frame bodies 34, 35 that are provided facing the side surface opening section have a first frame body structure section Q that is present in the tube wall along the entire circumference, and a second frame body structure section P that is present in the tube wall in a partial region 41A, which excludes the side surface opening section in the circumferential direction of the tube wall.

Abstract: Provided is a stent that can be easily placed in a branch portion of a living body lumen by a single manual operation, and that can be easily removed after placement. The stent of the present invention is placed in a living body lumen (hepatic portal portion HP) and is provided with: a tubular first stent portion which is placed in a common hepatic duct and includes a first framework portion; and tubular second stent portions which are placed in a right hepatic duct and a left hepatic duct branched from the common hepatic duct, and which include second framework portions. The stent is formed such that the first stent portion and the second stent portions can be integrally placed in the common hepatic duct, the right hepatic duct, and the left hepatic duct.

Abstract: In a safety apparatus for medical needles, when leg portions are extended from a first folded position to a second extended position, a distal end of a needle is introduced into a space of a shield member connection hub, and a first blocking wall and a second blocking wall overlap so as to block the cross section of the space to form a double blocking wall and blocks the cross section of the space. The double blocking wall is capable of preventing the distal end of the needle from moving downward from the double blocking wall and preventing the distal end of the needle from being exposed to the outside of the apparatus.

Abstract: The present invention provides an intravascular indwelling medical device having a structure capable of occluding a desired site within a blood vessel in a shorter time. An intravascular indwelling medical device (100) of the present invention is an intravascular indwelling medical device that dwells within a blood vessel (360) to occlude the blood vessel (360). The intravascular indwelling medical device (100) includes a mesh-form main body part (10) and a water-absorbing swelling material (20) that is disposed within the main body part (10) and swells upon absorbing water.

Abstract: This covered stent 100, which is released from a sheath 200 and placed in a lumen in a living body, is provided with: a tubular skeleton portion 11 which is stretchable in the axial direction and is expandable in the radial direction substantially perpendicular to the axial direction; and a stretch restriction portion 2 for restricting stretching of the skeleton portion in the axial direction. The stretch restriction portion is formed from a material different from that of the skeleton portion and restricts stretching of the skeleton portion in the axial direction when the skeleton portion is contracted in the radial direction while being stored in the sheath.

Abstract: Provided is a stent which is not easily displaced from a dwell site in a biological lumen and which has an excellent ability to follow a biological lumen. This stent (bile duct stent 100) is to dwell inside a biological lumen (bile duct B) and is provided with a stent main body section (110) having a cylindrical shape. The stent main body section is configured to be capable of expanding and contracting in the radial direction that is approximately orthogonal to an axial direction, has a relatively large expanding force in one portion (center portion) corresponding to the predetermined position at the indwelling site in the biological lumen, and a relatively small expanding force at other portions (both end portions) which have different positions in the axial direction from that of the one portion.

Abstract: A tubular endoprosthesis designing apparatus that designs a stent graft to be housed in a sheath includes a three-dimensional model generating unit, a simulation unit, and an opening position determination unit. The three-dimensional model generating unit generates a three-dimensional model of a blood vessel in which a stent graft is to be implanted. The simulation unit simulates a state in which a sheath is inserted into the three-dimensional model generated by the three-dimensional model generating unit. The opening position determination unit determines the position of the opening to be formed in the tubular wall of the stent graft based on the simulation result obtained by the simulation unit and the information with respect to the shape of twisting of the blood vessel in a region in which the stent graft is to be implanted.
