1. A ureteral catheter comprising (a) a proximal portion;
- and (b) a distal portion, the distal portion comprising a retention portion that comprises one or more protected drainage holes, ports or perforations and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports or perforations upon application of negative pressure through the catheter, wherein the retention portion is configured into a funnel-shaped support having an outer surface and an inner surface, and wherein the outer periphery or protective surface area comprises the outer surface of the funnel-shaped support, and the one or more drainage holes, ports or perforations are disposed on the inner surface of the funnel-shaped support.

Abstract
Ureteral or bladder catheters are provided, including (a) a proximal portion; and (b) a distal portion, the distal portion including a retention portion that includes one or more protected drainage holes, ports or perforations and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports or perforations upon application of negative pressure through the catheter. Systems, kits and methods for inducing negative pressure to increase renal function also are provided.

11. A system for inducing negative pressure in a portion of a urinary tract of a patient, the system comprising:
-
(a) at least one ureteral catheter, the at least one ureteral catheter comprising a distal portion configured for insertion within the patient'"'"'s kidney and a proximal portion; (b) a bladder catheter comprising a distal portion configured for insertion within the patient'"'"'s bladder and a proximal portion for receiving negative pressure from a negative pressure source, wherein at least one of the at least one ureteral catheter(s) or the bladder catheter comprises (a) a proximal portion; and
(b) a distal portion, the distal portion comprising a retention portion that comprises one or more protected drainage holes, ports or perforations and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports or perforations upon application of negative pressure through the catheter; and(c) a negative pressure source for application of negative pressure through both the bladder catheter and the ureteral catheter(s), which in turn causes fluid from the kidney to be drawn into and through the ureteral catheter(s), then through the bladder catheter, and then outside of the patient'"'"'s body. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system for inducing negative pressure in a portion of a urinary tract of a patient, the system comprising:
-
(a) at least one ureteral catheter, the at least one ureteral catheter comprising a distal portion configured for insertion within the patient'"'"'s kidney and a proximal portion; (b) a bladder catheter comprising a distal portion configured for insertion within the patient'"'"'s bladder and a proximal portion for receiving a negative pressure, wherein the negative pressure causes fluid from the kidney to be drawn into and through the ureteral catheter(s), then through the bladder catheter, and then outside of the patient'"'"'s body, wherein at least one of the at least one ureteral catheter(s) or the bladder catheter comprises (a) a proximal portion; and
(b) a distal portion, the distal portion comprising a retention portion that comprises one or more protected drainage holes, ports or perforations and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports or perforations upon application of the negative pressure through the at least one ureteral catheter(s) or the bladder catheter.- View Dependent Claims (24, 25, 26, 27, 28)
