PROBLEM TO BE SOLVED: To provide a catheter with a kin-resistant membrane assembly. SOLUTION: This catheter is equipped with: a) an outer assembly with an outer polymer film and a superelastic alloy ribbon braid member inside the outer polymer membrane; b) an inner tube assembly placed inside the outer tube assembly at an interval from the outer tube assembly to form a ring space in between the outer tube assembly and the inner tube assembly, and c) a film assembly with an outward inflatable membrane, which is at a distal position of the outer tube assembly, is connected at a distal position to the distal end of the inner tube assembly, and forms an inflatable cavity fluid-communicated to the ring space in between the outer tube assembly and the inner tube assembly. |
