A system for removing fluid from a urinary tract includes at least one sensor configured to detect signal(s) representative of pulmonary artery pressure and communicate signal(s) representative of the pulmonary artery pressure and a controller. The controller is configured to: receive and process the signal(s) from the at least one sensor to determine if the pulmonary artery pressure is above, below, or at a predetermined value; and provide a control signal, determined at least in part from the pulmonary artery pressure signal(s) received from the at least one sensor, to a negative pressure source to apply negative pressure to a urinary catheter to remove fluid from a urinary tract when the pulmonary artery pressure is above the predetermined value and to cease applying negative pressure when the pulmonary artery pressure is at or below the predetermined value.

Negative pressure therapy system and methods

A pump for inducing negative pressure in the ureter and/or kidney is provided. The pump is configured to be in communication with at least one lumen of at least one ureteral catheter and to draw fluid from the ureter and/or kidney into the at least one lumen of the at least one ureteral catheter for removal of the fluid from the ureter and/or kidney. The pump is configured to induce negative pressure ranging from about 0.1 mmHg to about 50 mmHg gauge pressure proximate to the pump inlet, and the pump is configured to have an accuracy of about 10 mmHg or less proximate to the pump inlet.

Pump, system and methods of inducing negative pressure to increase renal perfusion

A medical device reduces the risk of operating room fires caused by light sources by shielding the illuminated light cable from directly interacting with surgical drapes or patient skin. The device includes a silicone housing that mates circumferentially over existing endoscopic light cables and a thermal insulator can be positioned over the light emitting tip of the cable.

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.

Ureteral catheters, bladder catheters, systems, kits and methods for inducing negative pressure to increase renal function

Negative pressure therapy systems are provided for increasing urine production, the negative pressure therapy system including: (a) a pump assembly, the pump assembly including: (i) a pump configured to provide negative pressure to a kidney, and (ii) a controller configured to regulate the negative pressure provided by the pump within a pressure range that facilitates increased urine production from the kidney.

Negative pressure therapy system

A negative pressure therapy system is provided for inducing negative pressure in a portion of a urinary tract of a patient, the system including: (a) at least one ureteral catheter configured to be positioned within a ureter and/or kidney of a patient; (b) one or more sensor(s) configured to determine information about urine produced within a urinary tract of the patient; and (c) a controller configured to increase urine production of the patient by adjusting one or more operating parameters of a negative pressure source for inducing negative pressure through the at least one ureteral catheter into the urinary tract of the patient, based at least in part upon the information determined by the one or more sensor(s).

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.

Systems and methods for inducing negative pressure in a portion of a urinary tract of a patient

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.

Method of removing excess fluid from a patient with hemodilution

Ureteral catheters and assemblies are provided including: a drainage lumen including 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 ureter and/or kidney, the distal portion including a coiled retention portion including at least a first coil having a first diameter and a second coil having a second diameter, the first diameter being less than the second diameter; or wherein the retention portion extends radially outwardly from a portion of the distal end of the drainage lumen portion, the retention portion including a proximal end having a first diameter, a distal end having a second diameter, and a wall and/or surface extending therebetween, the retention portion having a second diameter is greater than the first diameter when deployed; or wherein the retention portion includes a plurality of drainage tubes.

Ureteral and bladder catheters and methods of inducing negative pressure to increase renal perfusion

Ureteral catheters and assemblies are provided including: a proximal portion; and a distal portion, the distal portion including a retention portion, wherein the retention portion includes an inwardly facing side including one or more drainage ports and an outwardly facing side, and wherein, when negative pressure is applied through the ureteral catheter, fluid is drawn into the ureteral catheter through the one or more drainage ports while mucosal tissue is prevented from appreciably occluding the one or more drainage ports.

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.

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.
