Abstract
A ureteral catheter for placement in a kidney, renal pelvis, and/or in a ureter adjacent to the renal pelvis of a patient, includes: an elongated tube having a proximal end, a distal end, and a sidewall extending between the proximal end and the distal end of the tube defining at least one drainage lumen extending through the tube; and an expandable retention portion configured to transition from a retracted position to a deployed position and which, in the deployed position, defines a three-dimensional shape positioned to maintain fluid flow from the kidney through at least the distal end of the tube.
