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 percutaneous urinary catheter configured to be deployed in a urinary tract, including: (a) a proximal portion; and (b) a distal portion including a retention portion configured to be deployed in a kidney and/or a renal pelvis, the retention portion including 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.

Percutaneous urinary catheter

A percutaneous urinary catheter is provided, including a proximal portion, a distal portion configured to be deployed in a kidney and/or renal pelvis of the urinary tract, and at least one lumen extending at least partially through the proximal portion of the percutaneous urinary catheter; and a negative pressure source in fluid communication with the at least one lumen, the negative pressure source being configured to draw fluid from the urinary tract into the at least one lumen of the percutaneous urinary catheter for removal of the fluid from the urinary tract.

A coated urinary catheter or urinary stent device includes a urinary catheter or stent which, in a deployed position, includes or defines a protective surface area and a protected surface area and a coating upon at least a portion of the protective surface area. The coating includes a lubricant and an antimicrobial and/or pH buffering material. The device is configured such that, upon application of negative pressure to the catheter or stent, tissue of a urinary tract of a patient conforms or collapses onto the protective surface area and is thereby prevented or inhibited from occluding one or more protected drainage holes, ports or perforations of the catheter or stent.

Coated urinary catheter or ureteral stent and method

A catheter configured to be deployed in a urinary tract of a patient includes a proximal portion configured to pass through a percutaneous opening and a distal portion including a retention portion. The retention portion is configured to be deployed in a kidney, renal pelvis, and/or bladder of the patient. The retention portion includes one or more protected drainage holes, ports or perforations and is configured, when deployed, 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.
