Title:
PERCUTANEOUS CATHETER
Document Type and Number:
WIPO Patent Application WO/2021/172155
Kind Code:
A1
Abstract:
[Problem] To provide a percutaneous catheter whereby burden on the body of a patient is suppressed, loss of pressure of a liquid during circulation thereof in a circulation circuit is reduced and the required flow rate of the liquid is ensured, and stylet tightening can be suitably prevented when a stylet is inserted. [Solution] A percutaneous catheter 30 has an expansion part 32, a shaft part 33, and a middle part 34. The expansion part has first reinforcement bodies 321 comprising wires W that are braided so as to intersect, the shaft part has second reinforcement bodies 331 comprising wires that are braided so as to intersect, and the middle part has third reinforcement bodies 341 comprising wires that are braided so as to intersect. The third reinforcement bodies are configured so that braiding angles thereof, which are the axial-direction interior angles from among the angles formed by the intersecting wires, are smaller than the braiding angles of the first reinforcement bodies and the second reinforcement bodies.
