| 摘要 |
The invention concerns a catheter (1) designed to be inserted in a corporeal duct and comprising a flexible elongated body, rigid in traction, including a sealed tubular sheath (3) for transmitting a fluid under pressure and capable of being subjected to radial collapse. Said catheter is characterised in that said sheath (3) is made at least partially of a flexible material and has a thin wall (4) with uneven surface, such that, when said sheath (3) is subjected to such a radial collapse, the irregularities at the surface thereof maintain a fluid communication (7) between said sheath (3) ends.
