Relieving Congestion in Acute Heart Failure (AHF) Patients.








AHF Background

Heart failure (HF) is a chronic, progressive disease in which the heart is unable to pump enough oxygen-rich blood to the body. Acute HF is the sudden worsening of this condition, mostly due to fluid congestion. Increase in blood volume elevates vascular pressure and affects the kidneys’ ability to exert urine and sodium, causing build-up in the extremities (edema), lungs (dyspnea), and other internal organs.

The key treatment is diuretic therapy, aimed at increasing the patient’s urine and sodium output.

Poor or delayed response to diuretics leads to increased mortality, longer hospitalization, and higher 30-day re-admission rates. This direct financial impact is not reimbursed to the hospitals, with potential added risk from The Affordable Care Act penalties.

Relieves congestion, restores organ function, enhances diuretic efficiency

The Doraya is designed to improve the efficacy of diuretic therapy in patients with acute heart failure (AHF). A manageable flow-reducing Central Venus Catheter, Doraya is deployed in the infrarenal IVC for up to 12 hours, helping cardiologists to temporarily manage venous hemodynamics, central venous pressure, renal afterload, and venous returns. Data from the Doraya First in Human feasibility study was presented at THT 2022 and featured in the March 2022 release of the Journal of the American College of Cardiology: Basic to Translational Science, demonstrating promising results.

Revamp medical was founded in 2016 with the goal of resolving one of the most urgent unmet needs in Acute Heart Failure patients. We believe that by using Doraya, cardiologists can enhance patient response to diuretic therapy, thereby rapidly alleviate signs and symptoms of congestion, improving patient outcomes and significantly reducing the financial burden of readmission. Revamp has a seasoned team of professionals with a proven track record in leading multiple med-tech startups.
