A medical catheter comprising: a hub assembly; and an elongate shaft extending distally from the hub assembly, the elongate shaft including a proximal section, a midshaft section, and a distal section extending along a longitudinal axis of the shaft; the midshaft section including a cylindrical tubular member having a lumen and including a skived distal portion having a compound cut surface including a first planar cut surface portion through a wall of the cylindrical tubular member and a second planar cut surface portion through the wall of the cylindrical tubular member, wherein the first planar cut surface portion is non-parallel to the second planar cut surface portion and exposes the lumen of the cylindrical tubular member, wherein the first planar cut surface extends along a plane that transects the cylindrical tubular member at an acute angle to the longitudinal axis, wherein the second planar cut surface portion extends substantially parallel to the longitudinal axis and extends to a distal end of the midshaft section; the distal section including an outer tubular member and an inner tubular member disposed within the outer tubular member; and wherein the skived distal portion of the tubular member overlaps a proximal portion of the outer tubular member of the distal section.
