ClinConnect Summary
The WRAP Study is investigating a new device called the WRAPSODY Endoprosthesis System, which is designed to help treat problems with blood flow in patients who are on chronic hemodialysis. Specifically, it aims to find out how safe and effective this device is for people who have blockages or narrowing in the veins used for dialysis. This study is currently recruiting participants aged 18 and older who have been using a mature hemodialysis access, such as an arteriovenous (AV) fistula or graft, for their treatments.
To participate in this study, individuals must provide consent and agree to follow-up visits for two years. They should be undergoing regular hemodialysis and have a specific blockage in their dialysis access that can be treated with the WRAPSODY device. However, there are certain conditions that would exclude someone from joining, such as having an active infection at the access site or if they are planning to abandon their dialysis access within six months. Participants can expect close monitoring and support throughout the study period to ensure their safety and to gather important information about the treatment's effectiveness.
