  • Publication number: 20220320841
    Abstract: A sheath structure includes an outer member, and an inner member formed in a cylindrical shape in a state in which a first portion and a second portion are engaged with an engaging portion, and capable of being fitted into the outer member from an end portion of the outer member. In the inner member, the first portion and the second portion are not engaged with the engaging portion but interfere with the end portion of the outer member and are not capable of being fitted into the outer member, when a maximum insertable number of the predetermined routed members insertable into the outer member are inserted therein. The first portion and the second portion are engaged with the engaging portion and capable of being fitted into the outer member, when the predetermined routed members of a prescribed number smaller than the maximum insertable number are inserted therein.

  • Publication number: 20220214002
    Abstract: A corrugated-tube protective member includes a tubular main body configured to be arranged inside of an end part of a corrugated tube with ridge portions disposed along its longitudinal direction, a rib on an outer circumference of the main body arranged inside the corrugated tube and configured to engage with the ridge portion in a removal direction of the main body from the corrugated tube, and a stopper at an end part of the main body having an outer diameter set to be equal to or larger than that of the ridge portion and configured to be arranged to oppose an end surface of the corrugated tube. An interval between the stopper and the rib is set to be equal to or larger than an interval between engaged surfaces on the ridge portions adjacent to each other, the engaged surface being a surface configured to engage with the rib.

  • Publication number: 20220214003
    Abstract: A corrugated-tube protective member includes a tubular main body configured to be arranged inside of an end part of a corrugated tube. At least one portion in a circumferential direction of the main body has a dividing portion dividing the main body in the circumferential direction. The dividing portion includes an engagement portion. The engagement portion holds a first dividing surface and a second dividing surface facing each other in circumferential direction of the main body in an engaged state. The first dividing surface includes a first top part protruding toward the second dividing surface side. The second dividing surface includes a second bottom part indented to an opposite side of the first dividing surface and configured to engage with the first top part. The engagement portion includes a locked part formed on the first top part and an elastically deformable locking part formed on the second bottom part.

  • Patent number: 9656042
    Abstract: The presently disclosed subject matter relates to a catheter and method. The catheter can be configured as a guiding catheter with a flexible shaft section, a hub disposed at a proximal portion of the shaft section, and a strain relief section that surrounds a predetermined proximal-side range of the shaft section. A distal end of the strain relief section can be moved along an axial direction of the shaft section at least toward the side where the hub is located.

  • Patent number: 8435227
    Abstract: Disclosed herein is a catheter for a left coronary artery having a distal end for being introduced into an opening of the left coronary artery from an artery of an arm. The catheter can include a catheter main body including a main body portion of a substantially linear shape in a natural state thereof and a curved portion extending from the main body portion to form a portion that extends to the distal end and has a curved shape in a natural state thereof.

  • Patent number: 8246603
    Abstract: A catheter for a coronary artery can include a distal end for being introduced into an opening of a coronary artery from an artery of an arm. The catheter can, include a catheter main body including a main body portion having a substantially linear shape in a natural state and a curved portion forming a portion extending from the main body portion to the distal end and having a curved shape in a natural state. The curved portion can include a first curve extending in a curved state from the main body portion, an intermediate portion extending from the first curve, a second curve extending from the intermediate portion and curved in a direction same as that of the first curve, and an extreme distal end portion of a substantially linear shape extending from the second curve. A method of using the catheter is also disclosed.

  • Patent number: 8118804
    Abstract: A catheter assembly comprises an outer catheter including an outer catheter body and an outer catheter hub at a proximal portion of the outer catheter body; and an inner catheter including an inner catheter body insertable in the outer catheter body, a tip at the distal portion of the inner catheter body which is rich in flexibility, and an inner catheter hub at the proximal portion of the inner catheter body adapted to be coupled to the outer catheter hub. The inner catheter body includes a flexible section connected the tip, a physical property transition section on the proximal side of the flexible section, a first body section on the proximal side of the physical property transition section, a second body section on the proximal side of the first body section, greater than the first body section in flexural rigidity, and having a reinforcing material layer.
