A catheter , the catheter comprising: a distal length extending to a distal end, the distal length configured to indwell a cavity of a patient body, the distal length comprising: a first lumen extending longitudinally through a lengthwise portion of the distal length, the first lumen at least partially defined by a first inner diameter surface of the distal length; a second lumen extending longitudinally through the lengthwise portion of the distal length, the second lumen at least partially defined by a second inner diameter surface of the distal length; and a first fenestration disposed through a side wall of the first lumen , the first fenestration forming an outlet of the first lumen; and a proximal length including a proximal lengthwise portion of the first lumen and a proximal lengthwise portion of the second lumen, wherein a cuff element is disposed on an outer surface of the proximal length, wherein the first and second lumens of the distal length are formed within a binal portion having an ovular cross-section with relatively smooth and continuous outer-perimeter shape, the second inner diameter surface defining the second lumen having a diameter larger than the first inner diameter surface defining the first lumen, and wherein the catheter further comprises a bifurcated length located proximally of the binal portion , the bifurcated length including a first tube portion and a second tube portion that join at a junction , the first lumen extending longitudinally through the first tube portion , and the second lumen extending longitudinally through the second tube portion . a distal length extending to a distal end, the distal length configured to indwell a cavity of a patient body, the distal length comprising: a first lumen extending longitudinally through a lengthwise portion of the distal length, the first lumen at least partially defined by a first inner diameter surface of the distal length; a second lumen extending longitudinally through the lengthwise portion of the distal length, the second lumen at least partially defined by a second inner diameter surface of the distal length; and a first fenestration disposed through a side wall of the first lumen , the first fenestration forming an outlet of the first lumen; and a first lumen extending longitudinally through a lengthwise portion of the distal length, the first lumen at least partially defined by a first inner diameter surface of the distal length; a second lumen extending longitudinally through the lengthwise portion of the distal length, the second lumen at least partially defined by a second inner diameter surface of the distal length; and a first fenestration disposed through a side wall of the first lumen , the first fenestration forming an outlet of the first lumen; and a proximal length including a proximal lengthwise portion of the first lumen and a proximal lengthwise portion of the second lumen, wherein a cuff element is disposed on an outer surface of the proximal length, wherein the first and second lumens of the distal length are formed within a binal portion having an ovular cross-section with relatively smooth and continuous outer-perimeter shape, the second inner diameter surface defining the second lumen having a diameter larger than the first inner diameter surface defining the first lumen, and wherein the catheter further comprises a bifurcated length located proximally of the binal portion , the bifurcated length including a first tube portion and a second tube portion that join at a junction , the first lumen extending longitudinally through the first tube portion , and the second lumen extending longitudinally through the second tube portion . <EOS>
