Abstract: A fixing structure comprises a driveline, a fixing member, through which the driveline is inserted, and a holding mechanism to hold the driveline. The holding mechanism comprises a chuck member to grasp the driveline, a sealing member, and a screw member to press the chuck member and the sealing member. The sealing member has a main body portion, and an annular protruding portion projecting from an end of the main body portion, wherein a cross-sectional shape of the annular protruding portion gradually decreases in diameter toward the projecting direction. The annular protruding portion is configured to be bent and deformed to the inner side of the sealing member in the radial direction by contacting an end face of the chuck member.

Abstract: An artificial blood vessel is used, which alternatingly has, in an extending direction D2 of a weft yarn 2, a first region in which a warp yarn 1 and the weft yarn 2 are woven in a plain weave, a second region having a first portion on the second region side R21 in which the warp yarn 1 crosses over a plurality of weft yarns 2 and a second portion on the second region side R22 in which the warp yarn 1 extends so as to cross over one weft yarn 2, and a third region having a first portion on the third region side R31 in which the warp yarn 1 crosses over a plurality of warp yarns 2 and a second portion on the third region side R32 in which the warp yarn 1 extends so as to cross over one weft yarn 2.

Abstract: Provided is a cylindrical embedded material for medical use, in which a plurality of structure bodies are connected in an axial direction, wherein the structure body elements each have an enclosure part configured for enclosing inside thereof, wherein the cylindrical embedded material connection part in which a structure body element of a first structure body and a structure body element of a second structure body connected in the axial direction, wherein the enclosure part has a spacing part to separate the fibers, wherein the cylindrical embedded material has a covering part, and wherein the covering part has elasticity which allows for movement of the fibers to narrow the spacing part when an external force is applied to the structure body element and allows for restoration of positions of the moved fibers when the external force is removed.

Abstract: A tunnel device includes a base portion, a shaft to be connected to the base portion at one end of the shaft, and a tip portion to be connected to another end of shaft. The base portion is provided with a shaft connection portion to which the one end of shaft is connected. The shaft is provided with a shaft-side screw portion at the one end of the shaft. The shaft connection portion includes a shaft housing portion having an inner diameter substantially same as an outer diameter of the one end of the shaft, and a base-portion side screw portion provided on a further inner side relative to the shaft housing portion. The base portion and the shaft are fixed to each other by screwing between the shaft-side screw portion and the base-portion side screw portion.

Abstract: A holding mechanism assembly 1 includes: a tubular inserting member 2; a fixing device 3 having a fixing portion 31 and a communicating portion 32; and a holding structure 4 to hold the inserting member 2 to the fixing device 3 in a liquid tight manner. The communicating portion 32 has a first opening 321 opened toward the outside of the living body; a second opening 322 opened toward the inside of the living body; and a communication path 323 formed between the first opening 321 and the second opening 322. An outer surface 2a of the inserting member 2 has a covered region A1 covered with fiber that can guide cells and a non-covered region A2 not covered with fiber, and the non-covered region A2 extends between the holding structure 4 and the second opening 322.

Abstract: This device is an inserting member fixing device to fix a linear inserting member to an insertion target, the inserting member fixing device comprising: a main body; a chuck portion; an inner sealing portion to be brought into close contact with an outer periphery of the inserting member; an inserting member supporting portion to support the inserting member; and a movement restricting portion to restrict movement of the inner sealing portion and the inserting member supporting portion. The inserting member supporting portion and the inner sealing portion are provided adjacent to each other in an axial direction of the inserting member, and a space is provided between the inserting member supporting portion and the inner sealing portion so that a main body-side end portion of the inserting member supporting portion is displaceable when the inserting member swings.

Abstract: A fixing device capable of being fixed, by simple fixing, to a living body without causing an occurrence of inflammation is provided. The fixing device 3 is fixed beneath the skin of the living body and includes a porous portion 31a capable of inducing cells thereto and a flat portion 31b that allows the cells to be adhered thereto, the porous portion 31a and the flat portion 31b are provided adjacent to each other, and a virtual surface SF1 of the porous portion 31a and a surface SF2 of the flat portion 31b are substantially flush with each other.
