1. A catheter for the drainage of urine from a bladder, comprising: a catheter tube having a proximal end and a distal end and having a cylindrical wall with a lumen extending generally from the proximal end to the distal end to permit the passage of urine therethrough; the catheter tube being formed such that the proximal end thereof has a closed tip for insertion of the catheter tube through a urethra until the closed tip is positioned in the bladder and the distal end thereof has an opening for the drainage of urine from the bladder through the lumen of the catheter tube; the cylindrical wall having an outer surface with at least one defined external flow path extending generally in a longitudinal direction from a point to be positioned in the bladder in proximity to the closed tip to a point to be positioned in the urethra distally thereof; and at least one drainage eye associated with the defined external flow path when the point of the external flow path in proximity to the closed tip is positioned within the bladder, the drainage eye extending completely through the catheter tube from the outer surface to the lumen to permit urine in the flow path to pass through the drainage eye into the lumen.
