Abstract
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.
Claims38
A percutaneous urinary catheter configured to be deployed in a urinary tract, comprising:
- (a) a proximal portion;
- and
- (b) a distal portion comprising a retention portion configured to be deployed in a kidney and/or a renal pelvis, the retention portion comprising 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.
The percutaneous urinary catheter of claim 8, wherein the first coil is closer to the proximal portion of the catheter than is the second coil.
A system for inducing negative pressure in a portion of a urinary tract, the system comprising:
- (a) a percutaneous urinary catheter configured to be deployed in a urinary tract, comprising:
- (i) a proximal portion;
- and
- (ii) a distal portion comprising a retention portion configured to be deployed in a kidney and/or a renal pelvis, the retention portion comprising 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;
- and
- (b) a negative pressure source in fluid communication with the lumen, the negative pressure source being configured for inducing a negative pressure in a portion of the urinary tract to draw fluid through the lumen of the catheter.
A negative pressure therapy system for increasing urine production, the negative pressure therapy system comprising:
- (a) a pump assembly, the pump assembly comprising:
- (i) a pump configured to provide positive or negative pressure to a kidney, and
- (ii) a controller configured to regulate the positive or negative pressure provided by the pump within a pressure range that facilitates increased urine production from the kidney,
- (b) at least one percutaneous urinary catheter configured to be deployed in a urinary tract, comprising:
- (i) a proximal portion;
- and
- (ii) a distal portion comprising a retention portion configured to be deployed in a kidney and/or a renal pelvis, the retention portion comprising 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;
A method for removing fluid from a urinary tract of a patient, the method comprising:
- inserting a percutaneous urinary catheter through a percutaneous opening and into a kidney and/or renal pelvis;
- and
- deploying a retention portion of the catheter within the kidney and/or renal pelvis to maintain patency of fluid flow from the kidney through at least a portion of the catheter, wherein the catheter comprises:
- (i) a proximal portion;
- and
- (ii) a distal portion comprising a retention portion configured to be deployed in the kidney and/or the renal pelvis, the retention portion comprising one or more drainage holes leading to one or more lumen(s) within the proximal portion, and
- 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.
