Problems solved by technology

Exceeding normal blood volume in intravascular compartments can lead to high blood pressure, stress on the heart, and shortness of breath due to fluid accumulation in the pleural cavity, which reduces quality of life and even worsens other diseases such as CHF, leading to death

Abstract

A catheter (100) for treating hypervolemia in a patient includes a luminal ingress (112) joined to a luminal egress (114) at a distal end portion (116) of the catheter having a closed distal end (102). The distal end portion is configured to at least temporarily reside within a vessel of the patient, the distal end portion including a semipermeable membrane. The luminal ingress is designed to convey an influent having a first osmotic concentration to the distal end portion. The semipermeable membrane is configured to pass blood-borne water from the vessel into the distal portion. The blood- borne water is absorbed by the influent to produce an effluent having a second osmotic concentration lower than the first osmotic concentration. Systems (200) with the catheter and methods for treating hypervolemia are also disclosed.

Description

[0001] priority [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 750,124, filed October 24, 2018, which is hereby incorporated by reference in its entirety. Background technique [0003] Hypervolemia or fluid overload is a medical condition in which blood volume in the intravascular compartment exceeds normal levels due to excess water retained in the plasma. Water may build up in patients with chronic kidney disease, especially in advanced stages, such as end-stage renal disease ("ESRD"), in which the kidneys no longer efficiently filter out more water than the body needs. Water may also build up in patients with chronic heart disease such as congestive heart failure ("CHF"), in which the heart no longer efficiently pumps blood to the kidneys to filter out more water than the body needs. Exceeding normal blood volume in intravascular compartments can lead to high blood pressure, stress on the heart, and shortness of breath due t...
