  • Publication number: 20220218321
    Abstract: A hole closing material achieves less invasive treatment for atrial septal defect with no or little possibility of problems in the late post-treatment period. The hole closing material includes two tubular bodies (first tubular portion and second tubular portion) having a mesh structure formed of a bioabsorbable linear material, and includes: a proximal connecting part connected to a first end; and a distal connecting part connected to a second end and screwed to a delivery cable. The proximal connecting part and the distal connecting part are capable of selectively achieving: “locked” in which the proximal connecting part and the distal connecting part remain united; and “unlocked” in which the proximal connecting part and the distal connecting part do not remain united. The delivery cable passes through the substantially middle portion, is inserted into a hollow tube of the proximal connecting part, and passes out of the hole closing material in a direction from the second end to the first end.

  • 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.
