A catheter manifold for an angioplasty balloon catheter assembly houses a plurality of serially arranged luers. Longitudinal sections of the luers are joined by tubular connectors, and with the connectors form a central passage through the manifold. At the most distal tubular connector is a reduction in passage diameter. A plurality of elongate, longitudinally directed flutes are formed in that connector just proximal of the diameter reduction. The flutes are engaged by a guide wire insertion tube or fiber insertion tube as it is loaded into the manifold, and tend to center the tube in the passageway. The flutes tend to maintain it in coaxial relation to the passageway, while permitting fluids from the proximal luers to flow in the passageway exteriorly of the tube.
