Systems and methods for inducing negative pressure in a portion of a urinary tract of a patient
First Claim
Patent Images
1. A system for inducing negative pressure in a portion of a urinary tract of a patient, the system comprising:
- (a) a 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 application of negative pressure, the proximal portion configured to extend outside of the patient'"'"'s body; and
(c) a pump external to the patient'"'"'s body for application of negative pressure through both the bladder catheter and the ureteral catheter, which in turn causes fluid from the kidney to be drawn into the ureteral catheter, through both the ureteral catheter and the bladder catheter, and then outside of the patient'"'"'s body.

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.

14. A method for inducing negative pressure in a portion of a urinary tract of a patient, the method comprising:
-
deploying a ureteral catheter into a ureter of a patient to maintain patency of fluid flow between a kidney and a bladder of the patient, the ureteral catheter comprising a distal portion for insertion within the patient'"'"'s kidney and a proximal portion; deploying a bladder catheter into the bladder of the patient, wherein the bladder catheter comprises a distal portion for insertion within the patient'"'"'s bladder and a proximal portion for application of negative pressure, the proximal portion extending outside of the patient'"'"'s body; and applying negative pressure to the proximal end of the bladder catheter to induce negative pressure in a portion of the urinary tract of the patient to remove fluid from the patient. - View Dependent Claims (15, 16, 17, 18, 19)
