Claim 16:
17. A system for inducing negative pressure in a portion of a urinary tract, the system comprising:
at least one catheter comprising:
(a) a proximal portion, wherein the proximal portion is essentially free or free of drainage holes; and
(b) a distal portion comprising a retention portion configured to be deployed in a kidney and/or a renal pelvis, the retention portion comprising one or more drainage holes leading to one or more lumen(s) within the proximal portion,
wherein the retention portion, when deployed, defines a three-dimensional shape sized and positioned to maintain patency of fluid flow between the kidney and/or renal pelvis and a proximal end of the catheter by inhibiting mucosal tissue from appreciably occluding the one or more drainage holes when negative pressure is applied through the catheter; and
a negative pressure source in fluid communication with the lumen, the negative pressure source being configured for inducing a negative pressure in a portion of the urinary tract to draw fluid through the lumen of the catheter.
