Patent number: 10512713Abstract: 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.Type: GrantFiled: January 20, 2017Date of Patent: December 24, 2019Assignee: Strataca Systems LimitedInventors: John R.

Publication number: 20180264226Abstract: A urine collection catheter is provided. The catheter includes: a conduit having an open distal end; a drainage tube positioned at least partially within the conduit; and a bladder superior wall support. The drainage tube includes one or more fluid ports or perforations for permitting fluid flow into a drainage lumen defined by the drainage tube. The bladder superior wall support includes a support cap and a plurality of support members extending from a proximal surface of the support cap through the open distal end of the conduit. The support cap is capable of being moved between a retracted position and a deployed position. In the deployed position, the distal end of the drainage tube is spaced apart from the support cap, such that the support cap supports portions of the superior wall of the bladder from occluding the one or more fluid ports or perforations of the drainage tube.Type: ApplicationFiled: July 20, 2016Publication date: September 20, 2018Inventors: John R.
