The duct (10) in the catheter, which is intended to transport the hydraulic liquid for operating the balloon (1) of the catheter, has a crescent-shaped cross-section with end portions (12) which have small radii of curvature. These small radii of curvature favour the formation of menisci of considerable height which oppose the formation of gas-liquid fragments within the tube. <IMAGE> |
