Assessment of a Wearable Ultrafiltration Device

"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. Participants 01-09 will receive one week of baseline observation (three HD treatments) with two weeks of supervised intervention using RUF-D post HD on Mondays and Wednesdays for up to six hours (total three-week study).~Participants 10-18 will receive one week of baseline observation, two weeks of intervention (identical to cohort one above), with an additional week of intervention (total four weeks) where participants will be fitted with the RUF-D (ensuring functionality) before going home with the device in operation for up to six hours twice weekly."
