Abstract
A method is provided for facilitating urine output from the kidney, including: (a) inserting a catheter including: a drainage lumen including a distal portion configured to be positioned in a patient's kidney, renal pelvis and/or in the ureter adjacent to the renal pelvis and a proximal portion, the distal portion including a retention portion including a funnel support including at least one sidewall, wherein the funnel support includes a first diameter and a second diameter, the first diameter being less than the second diameter, the second diameter being closer to an end of the distal portion of the drainage lumen than the first diameter, wherein the proximal portion of the drainage lumen is essentially free of or free of openings; and (b) applying negative pressure to the proximal portion of the drainage lumen for a period of time to facilitate urine output from the kidney.
