Catheter for delivery of therapeutic liquid formulation

A catheter (100) for intraperitoneal drug delivery having a proximal end (10) and a distal end (12) for distribution of a liquid outflow, the catheter (100) comprising:

• a first longitudinal lumen (120) disposed with a plurality of outlets (122a to f) in a flow distribution region (130) for passage of the liquid outflow,
• a distribution inlet (110) to the first lumen (120) disposed within a longitudinal central region (132) of the flow distribution region (130),
• a second longitudinal lumen (140), wherein the second lumen (140) is in fluid connection with the first lumen (120) at the distribution inlet (110), and is provided at a proximal end (12) with a catheter inlet (142) for inflow of the liquid,
• the first (120) and second (140) lumens are comprised in a tube (160) wherein a lumen (162) of the tube is partitioned into the first (120) and second (140) lumens by a partitioning wall (150) attached to the tube lumen wall (164),
• the outlets (122a to c) of the plurality on the distal (12) side of the distribution inlet (110) are longitudinally positioned and sized in mirrored symmetry with the plurality of outlets (122d to f) on the proximal (10) side of the distribution inlet (110),
• the distal (12) terminal end and proximal (10) terminal end of the first (120) lumen are liquid sealed closed,
• the distal (12) terminal end of the second (140) lumen is liquid sealed closed,
• the proximal (10) terminal end of the second (140) lumen is open and forms the catheter inlet (142) for inflow of the liquid,
• wherein the plurality of outlets (122a to f) is configured to counteract a reduction in outflow as the distance from the distribution inlet (110) increases in the longitudinal direction (L).
