Patent number: 10799668Abstract: 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.Type: GrantFiled: October 24, 2019Date of Patent: October 13, 2020Assignee: Strataca Systems LimitedInventors: John R. Erbey, II, Jacob L. Upperco, David E. Orr, Michael Alan Fisher, Patrick William Strane, Lance Michael Black

Ureteral and bladder catheters and methods of inducing negative pressure to increase renal perfusion
Patent number: 10765834Abstract: 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.Type: GrantFiled: August 25, 2017Date of Patent: September 8, 2020Assignee: Strataca Systems LimitedInventors: John R.

Ureteral and bladder catheters and methods of inducing negative pressure to increase renal perfusion
Patent number: 10610664Abstract: 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.Type: GrantFiled: August 10, 2017Date of Patent: April 7, 2020Assignee: Strataca Systems LimitedInventors: John R. Erbey, II, Jacob L. Upperco, Michael Alan Fisher, Patrick William Strane, Lance Michael Black -

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. Erbey, II, Jacob L. Upperco, Michael Allen Fisher, Patrick William Strane, Lance Michael Black, David E. Orr
