The treatment delivered by the device, which is known as renal denervation, is a procedure where a catheter is placed inside the blood vessels (renal arteries) that go to the kidneys. Ultrasound energy is created when the catheter is connected to a power source known as a generator. The ultrasound energy will heat up a small area of tissue around the blood vessel to disable nerves that are surrounding the blood vessels.

REDUCED - Todoran: Clinical evaluation of the Therapeutic Intra-Vascular Ultrasound (TIVUS™) System for renal denervation in patients with uncontrolled stage 2 hypertension: This study is seeking participants with uncontrolled high blood pressure despite taking blood pressure medications. TIVUS, or Therapeutic IntraVascular UltraSound (TIVUS™) System, is designed to denervate (deaden) the nerves surrounding the renal arteries (blood vessels going to the kidneys) as a way to help lower blood pressure.

Amgen Lipoprotein - Waring: A Multicenter, Cross-sectional Study to Characterize the Distribution of lipoprotein (a) Levels Among Patients With Documented History of Atherosclerotic Cardiovascular Disease (ASCVD): This study is being done to learn more about Lipoprotein (a) (Lp (a) values in people with known history of Atherosclerotic Cardiovascular Disease (ASCVD). Lipoprotein (a) is a particle that carries cholesterol in the blood. ASCVD is a type of thickening or hardening of the arteries caused by a buildup of plaque in the walls of arteries. Plaque is made up of substances such as fats and cholesterol. Plaque can cause blockages in the arteries which could result in a heart attack. High levels of Lp(a) are directly associated with a higher risk of cardiovascular events such as heart attacks or aortic stenosis.
