Leaving this extra fluid in the body also causes undue bodily stress. Investigators need to find gentler, more tolerable ways to remove fluid from patients that need hemodialysis.\n\nOur investigators have designed and built a new, very small and very simplified device (RUF-D) that can do part of what a dialysis machine does. It doesn't clean the blood or replace the need for dialysis treatments, but it can provide additional and gentle removal of fluid between dialysis treatments which wasn't able to be taken off during a standard treatment session.",[13],"Device: RUF-D",[15],{"type":16,"name":17,"description":18,"armGroupLabels":19,"otherNames":20},"DEVICE","RUF-D","We have developed a simplified fluid removal device (RUF-D) to address the challenges that patients face with being unable to remove the fluid they need with standard dialysis.

In some people the ability of the kidneys to clean poisons out of the blood gets so low they need to be hooked up to a machine three times a week to do it for them. This is called dialysis. Unfortunately, although this treatment removes those waste products, people who need dialysis die much more often than people who don't need dialysis. Dialysis causes extreme stress on the body and leads to many organs being damaged.\n\nRemoving fluid from the body quickly causes the equivalent of repeated little heart attacks or little strokes in the brain. Many patients struggle to tolerate having all the fluid that they have drunk since their last dialysis session removed- without unpleasant symptoms of dangerously low blood pressure (which makes the damage worse).\n\nDialysis treatments can be done more slowly or more often, but that means having to spend a lot more time at the hospital and is difficult for the health system to be able to provide the extra treatment time.\n\nCould extra fluid be removed in between dialysis sessions? Up to now there has not been a way to effectively do this. Investigators have now designed and built an entirely new, very small and very simplified, device that can do part of what a dialysis machine does. It doesn't clean the blood or replace the need for conventional dialysis sessions, but it can provide additional and gentle removal of fluid which wasn't able to be taken off during a standard treatment session.\n\nIf this study is successful, it will be the first time that a wearable device has been successfully built and used to take off extra fluid when dialysis patients are not in the hospital. The ability to do this opens up the possibility of, 1) helping to treat patients (both making people feel better and live longer) who can't tolerate getting off all the fluid in the short 3-4 hours they are on the dialysis machine in the hospital, and 2) helping patients who feel OK having the fluid taken off but are silently being subjected to damage to their organs due to the rapid removal, have reduced damage.",[70,71],"Hemodialysis","Ultrafiltration",[70,71],"NOT_YET_RECRUITING","2026-04-28",{"date":76,"type":77},"2026-04-29","ACTUAL",{"date":79,"type":64},"2026-07-01",{"date":81,"type":64},"2027-12-31",{"name":5,"class":6},1]
