This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a device called ContraBand™ that is implanted into the blood vessels in your lungs during a minimally invasive procedure. The device works by gently narrowing these vessels, which reduces pressure in your heart and lungs and helps your heart pump blood more efficiently. Researchers hope this treatment will help people with heart failure breathe easier, exercise longer, and feel better overall.
Many people with heart failure have limiting symptoms even when taking the best available medications. This trial exists to see if this new treatment can help reduce the strain on the heart and improve quality of life in ways that current medications alone cannot.

If you qualify, you will undergo a procedure where doctors insert the ContraBand™ device through a catheter into your lung blood vessels—similar to a heart catheterization but with device placement. After the procedure, you will have follow-up visits to monitor how the device is working, check your symptoms, and measure your exercise capacity. The study will follow you over time to see whether the treatment improves your heart function and quality of life.
