Abstract:
A double lumen catheter comprising an elongated tube having unitary outer walls and a longitudinal planar septum dividing an interior of said tube into an inlet lumen defined by an outer wall and said septum and a longer return lumen, said inlet lumen extending from a proximal end of said tube to an end terminating in a distally forward facing aperture that terminates said outer wall of said inlet lumen to form a wall-less open spacing defined solely by said septum, said return lumen extending substantially contiguously with said inlet lumen from said proximal end of said tube to an end terminating in a distally forward facing aperture spaced in the longitudinal direction distally forward of said inlet lumen aperture, wherein said inlet lumen aperture is defined by an outer wall lip that tapers away from said septum in a proximal direction and said return is defined by an outer wall lip that tapers away from said septum in a proximal direction and a diverting structure extending from said outer wall of said return lumen and positioned distally forward of said aperture of said inlet lumen and said spacing and noncontiguous to said aperture to divert flow of treated fluid discharged from said return lumen away from said distally forward facing aperture of said inlet lumen.
