Abstract
A multi-path catheter includes an elongate tubular member and a withdrawal pathway along which unfiltered fluid is withdrawn in a distal to proximal direction. The withdrawal pathway originates at a distal point and is at least partially defined by the elongate tubular member. The elongate tubular member also defines, at least partially, at least one infusion pathway along which filtered fluid is returned in a proximal to distal direction. The at least one infusion pathway extends distally beyond the withdrawal pathway. First and second legs of the elongate tubular member are positioned on opposing sides of the withdrawal pathway at the distal point, and the at least one infusion pathway is at least partially defined by one of the first and second legs. The first and second legs have outer walls that are unattached to one another at distal ends thereof.
