Abstract:
A tube coupling device for connecting a tubular rigid stem to a flexible catheter tube which is adapted to be arranged around said tubular rigid stem, the flexible catheter tube having a proximal free end, the tube coupling device having a main axis, a wall, at least one inner lumen extending along said main axis, through the wall, and two opposite radially non-deformable distal and proximal free ends, said inner lumen axially widening out towards the proximal free end of the tube coupling device, so that the proximal free end of the flexible catheter tube radially expands in the widening when arranged around the tubular rigid stem, said widening being delimited, along the main axis, at a first end, by the proximal free end of the tube coupling device, and, at a second opposite end by an internal annular flange protruding from the wall of the tube coupling device, in said at least one inner lumen, at a location along the main axis which is intermediate between the proximal and the distal free ends of the tube coupling device, wherein the flange comprises slots, so that said flange is divided into different sectors.
