Abstract
A catheter includes an elongated tube having a distal portion having a distal end and a sidewall defining at least one drainage lumen. The catheter also includes a permeable material. The permeable material is configured to be deployed in the urinary tract to maintain the distal end of the elongated tube at a predetermined position in a bladder, a ureter, a renal pelvis, or a kidney of the patient. When deployed, the permeable material defines a three-dimensional shape of sufficient size to permit flow of at least a portion of fluid from the urinary tract through the permeable material and the at least one drainage lumen.
