A blood treatment catheter includes a withdrawal lumen (16) and a supply lumen (18) in a joined segment (20) proximal to a dividing point (25) and in first and second unjoined tubes (24, 22), respectively, distal of the dividing point (25). The first tube (24) has a length greater than that of the second tube (22). There is an aperture (36) in the sidewall of the first unjoined tube (24) spaced distally from the dividing point (25). The catheter also includes a stiffening tube (12) capable of passing through the second unjoined tube (24), through the aperture (36) and extending distally of the aperture (36) through the first unjoined tube (24). <IMAGE> |
