A medical catheter, which comprises: an elongate catheter member defining a longitudinal axis and a transverse axis transverse to the longitudinal axis, and having a proximal end and a distal end, the elongate catheter member including an outer member and at least one longitudinal lumen within the outer member for passage of fluids, the outer member defining an elongate opening there through in communication with the at least one longitudinal lumen and being spaced proximally from a distal end of the at least one longitudinal lumen and bound by wall portions of the outer member, the elongate opening permitting fluids to pass between the at least one longitudinal lumen and locations external to the elongate catheter member, and defining a transverse dimension increasing from proximal to distal; the wall portions including a first side wall extending substantially parallel to the longitudinal axis, an end wall extending substantially parallel to the transverse axis and a second side wall which diverges outwardly from the first side wall, the end wall being positioned proximally of the distal end of the outer member, each of the elongate openings defining a transverse dimension increasing from a proximal end of the elongate opening to a distal end of the elongate opening.
