  • Patent number: 11065417
    Abstract: A catheter manufacturing method includes positioning a shaft in a cavity of a mold. The shaft is an elongated tubular body configured to be inserted into a living body. The mold includes a first mold die and a second mold die that contact one another to define a closed space which is the cavity. The method includes injecting a molding material into the cavity from a gate at a position between the proximal end and the distal end of the shaft in the axial direction. The injecting position is offset from the center of the shaft in the transverse direction. The method includes molding a hub onto the shaft by solidifying the injected molding material in the cavity onto the outer surface of the shaft.

  • Patent number: 10213578
    Abstract: A catheter assembly includes an outer catheter and an inner catheter. The inner catheter has an accommodation unit which can be positioned on a farther distal side than an outer catheter body in a state where an inner catheter body is inserted into the outer catheter body, extends in a proximal direction from the inner catheter body, and can accommodate an outer catheter distal portion so as to surround an outer circumference thereof in a state where the outer catheter distal portion formed at a distal end of the outer catheter body is reduced in diameter. The outer catheter distal portion can be separated from the accommodation unit and can expand in diameter by moving the inner catheter body in a distal end direction relatively with respect to the outer catheter body from a state of being accommodated in the accommodation unit.

  • Publication number: 20170151417
    Abstract: A catheter includes: a catheter shaft; and a hub on a proximal side of the catheter shaft. The catheter shaft includes a shaft inner surface inclined portion at a proximal portion, the diameter of which increases proximally such that the shaft inner surface inclined portion forms an angle with the catheter central axis. The hub includes a first hub inner surface inclined portion continuous from the shaft inner surface inclined portion and inclined at the same inclination angle as the shaft inner surface inclined portion, and a second hub inner surface inclined portion proximal of the first hub inner surface inclined portion. The second hub inner surface inclined portion inclination angle differs from the first hub inner surface inclined portion inclination angle. The hub does not cover an inner peripheral surface of the catheter shaft in an interlock portion in which the catheter shaft and the hub are interlocked together.
