  • Publication number: 20210177388
    Abstract: An in-tube transit object that is inserted in a tube includes: a coil section formed by winding a wire; and a fiber section attached to an end on one side and an end on the other side in a winding-axis direction of the coil section. The coil section is formed with a large diameter section, through which fiber of the fiber section is inserted, at the end on the one side and the end on the other side, and is inserted in an extending state in the winding-axis direction when the in-tube transit object is inserted into the tube. The fiber section is configured to expand when seen in the winding-axis direction in the case where the in-tube transit object is inserted in the tube and then discharged from the tube, which brings the coil section into a compressed state in the winding-axis direction.

  • Publication number: 20180103956
    Abstract: Provided is a defect hole closing material that has almost no fear of long-term failure and allows minimally invasive treatment for an atrial septal defect. The defect hole closing material is formed of two tubular bodies (a first tubular part and a second tubular par) having a stitch-like structure of a bioabsorbable material, has a sandglass shape, figure-of-eight shape, double spindle shape, or peanut shape, and includes a coil spring of which both ends are respectively engaged with a first end part and a second end part and that is passed through the insides of the first tubular part and the second tubular part from the first end part side to the second end part side via a substantially middle part. When pushing the defect hole closing material out of a catheter, the action of the coil spring causes the first tubular part and the second tubular part to come close with the substantially middle part as a center and expand tube diameters.
