Abstract: A method is provided for facilitating urine output from the kidney, including: (a) inserting a catheter including: a drainage lumen including a distal portion configured to be positioned in a patient's kidney, renal pelvis and/or in the ureter adjacent to the renal pelvis and a proximal portion, the distal portion including a retention portion including a funnel support including at least one sidewall, wherein the funnel support includes a first diameter and a second diameter, the first diameter being less than the second diameter, the second diameter being closer to an end of the distal portion of the drainage lumen than the first diameter, wherein the proximal portion of the drainage lumen is essentially free of or free of openings; and (b) applying negative pressure to the proximal portion of the drainage lumen for a period of time to facilitate urine output from the kidney.

Abstract: A method for increasing urine output rate from a patient having venous congestion is provided. The method includes: deploying a urinary catheter into the patient such that flow of urine from the ureter and/or kidney is transported within a drainage lumen of the catheter; applying negative pressure to the ureter and/or kidney through the drainage lumen of the catheter to extract urine from the patient; periodically measuring an edema value of the patient; and if the measured edema value is less than or equal to Grade 1 in which the depth of indentation is less than about 2 mm after about 10 seconds, ceasing the application of the negative pressure to the ureter and/or kidney.

Abstract: A bladder catheter is provided. The bladder catheter includes: a proximal portion configured to be positioned in at least a portion of a patient's urethra; and a distal portion configured to be positioned in a patient's bladder, the distal portion including a retention portion, wherein the retention portion includes an inwardly facing side including one or more perforations and an outwardly facing side, and wherein, when negative pressure is applied through the bladder catheter, fluid is drawn into the bladder catheter through the one or more perforations while bladder walls are prevented from appreciably occluding the one or more perforations by contact with the outwardly facing side of the retention portion.

Abstract: Ureteral or bladder catheters and systems are provided, including (a) a proximal portion; and (b) a distal portion, the distal portion including a retention portion including an outer periphery or protective surface area which prevents mucosal tissue from occluding one or more protected drainage holes, ports, or perforations disposed within the outer periphery or protective surface area upon application of negative pressure through the catheter.

Abstract: Ureteral catheters are provided including a drainage lumen including a distal portion configured to be positioned in a patient's kidney, renal pelvis and/or in the ureter adjacent to the renal pelvis for receiving fluid from a patient's kidney and a proximal portion for draining the fluid from the distal portion, the distal portion including a coiled retention portion including: at least a first coil having a first diameter; at least a second coil having a second diameter, the first diameter being less than the second diameter, the second coil being closer to an end of the distal portion of the drainage lumen than the first coil; and one or more perforations on a sidewall of the coiled retention portion of the distal portion of the drainage lumen for permitting fluid flow into the drainage lumen, wherein the proximal portion of the drainage lumen is essentially free of or free of perforations.

Abstract: A method for removing excess fluid from a patient with hemodilution is provided. The method includes: deploying a urinary tract catheter into the patient such that flow of urine from the ureter and/or kidney is transported within a drainage lumen of the catheter; applying negative pressure to the ureter and/or kidney through the drainage lumen of the catheter to extract urine from the patient; periodically measuring a hematocrit value of the patient; and if the measured hematocrit value is greater than a predetermined threshold value, ceasing the application of the negative pressure to the ureter and/or kidney. A system for removing excess fluid from a patient with hemodilution including a ureteral catheter and a pump is also provided.

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.

Abstract: The present invention provides a method and device for visualizing and treating an injury, wound or skin using a visual tourniquet and skin patch system made of transparent materials. The inventive bandage system is capable of applying pressure while absorbing bodily fluids away from the wound or skin and providing support for the application of one or more medicaments or a combination of treatment gas and/or medicine. The inventive bandage system enables the practitioner to visually inspect and measure the size of the wound over time without removing or touching the bandage or tourniquet thereby reducing pain and contamination of the wound bed. One embodiment of the inventive bandage system continuously controls the wound bed temperature thereby reducing pain and inhibiting bacterial growth. Other embodiments of the inventive bandage system are used as a visual tourniquet to apply a combination of pressures to a wound or skin.
