    Abstract: A medical tube, which is inserted into a tubular organ and discharges and suctions fluid, is provided with a tube-shape main body which extends a prescribed length and with a valve which is disposed in a portion of the main body that is inserted into the tubular organ and can discharge or suction a fluid, wherein the valve includes multiple slits which are formed so as to extend axially of the body a prescribed length, reaching from the outer periphery to the inner periphery of the main body, and which are provided spaced in the circumferential direction of the main body. Each slit is formed tilted in the same direction with respect to a radially-extending line which passes through the axial center of the main body.

    Abstract: There is provided a medicinal liquid injection port to be implanted subcutaneously. A housing main body is provided with a medicinal liquid storage portion therein, an opening portion that opens the medicinal liquid storage portion, and a discharge hole that communicates with the medicinal liquid storage portion and configured to be connected with a tube. A septum attached to the opening portion of the housing main body and provided with a puncturable region that can be punctured with a puncture needle. A contrast portion is disposed in the septum over a thickness direction of the septum so as to detect the puncturable region of the septum with the ultrasonic wave. The contrast portion is provided in the septum within a thickness region of the septum and all of the contrast portion is positioned at an inner side of the septum in the thickness direction of the septum.

    IPC: A61B17/221

    Abstract: Provided is an intraluminal foreign object capturing tool with which it is possible to cause a capturing member for capturing a foreign object to expand to an appropriate diameter. The foreign object capturing tool, in order to capture a foreign object in a lumen, includes: a core wire; a capturing member which is disposed movably outside the core wire, has a farthest tip-end which is movement-regulated at a predetermined position of the core wire, and expands in diameter by contracting axially; a tubular member which is disposed outside the core wire on a base end side of the capturing member, and which regulates movement of capturing member on the base end side; and control members which are disposed outside the core wire and inside the capturing member, and which regulate the amount of axial contraction of the capturing member. As the tubular member and the core wire are moved relative to each other, the capturing member contracts axially by a length regulated by the control member and expands in diameter.

    Abstract: One embodiment provides a balloon catheter which has an inner tube having a main lumen and an outer tube which forms an expansion lumen. A part of the inner tube is connected to the outer tube at a position closer to the proximal end than a balloon, a side hole is open at the connection section, and a weak section is provided to the inner tube a position closer to the distal end than the side hole. The weak section has lower rigidity than the remaining portion of the inner tube. When the balloon is expanded by fluid supplied to the expansion lumen, the weak section is pressed by the fluid pressure to thereby close the main lumen of the inner tube.

    Abstract: A stent, in which a silicone film can be formed in a small thickness and uniformly and the diameter of the stent can be reduced, includes: a tubular stent main body which is formed by processing a metal tube or a metal sheet or weaving a metal wire material and has mesh-like openings; an inside cover which is so coated around the stent main body as to cover the mesh-like openings and is composed of a polyurethane film; and an outside cover which is coated on the outer periphery of the stent main body and the inside cover and is composed of a silicone film.
