The purpose of this study is to see whether a medical device called the Paradise Renal Denervation System (also called The Paradise System) can lower high blood pressure in participants who are known to have hypertension. The device and the treatment delivered by the device, which is known as renal denervation, are investigational in the United States because they haven't been approved by the US Food and Drug Administration (FDA). 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. This is a continued access protocol meaning studies have already been done using this device.
This study is for participants who take 3 or more high blood pressure medications but continue to have high blood pressure. This is a five year study consisting of in person visits at screening, baseline, pre procedure testing, procedure and visits at 1,2,3,4,5,6,12,24,36,48 and 60 months. Study related testing includes BP measurements including 24 hour blood pressure readings, electrocardiograms (ECG), blood work, urine studies, and CT scans. Risks associated with this study include procedure risks such as pain, bleeding or bruising at the catheter insertion site. There are other study related risks such as risks of blood draws, radiation risk associated with the CT scan and loss of confidentiality.
This study is seeking participants with narrowing of the blood vessels of their lower limbs. The purpose of this study is to determine if treating a blockage in blood vessel in the leg has a better long term outcome when placing a stent like device called a scaffold that is coated with a medication after ballooning open the vessel compared to opening the vessel with the balloon only. The scaffold device is called the Esprit™BTK Everolimus Eluting Bioresorbable Scaffold System and is considered investigational meaning it has not been approved for commercial use by the US Food and Drug Administration. The study is designed to last 5 years and will include up to 10 visits.
This is a study for patients with high blood pressure. The purpose of this study is to evaluate the safety and effectiveness of renal denervation while you are still on your blood pressure medications. Renal denervation is a procedure that destroys the nerve fibers that run along the kidney blood vessels interrupting nerve signals that may cause high blood pressure.The purpose of the treatment (renal denervation) is to lower blood pressure. You will undergo renal angiography (RA), which you may or may not receive the study treatment (depending upon your study assignment). The sponsor has manufactured a new drug/device combination product called the Peregrine System™ Kit (also referred to as the Peregrine Kit). The Peregrine Kit contains a device, the Peregrine System™ Infusion Catheter (also referred to as the Peregrine Catheter), and a drug dehydrated alcohol for injection (also referred to as alcohol). Therefore, the effectiveness of the study catheter and the alcohol (Peregrine Kit) will be assessed by how well the treatment reduces your blood pressure. The participant will be asked to return to the doctor's office for follow-up visits at 4 and 8 weeks, 3, 4, 5 and 6 months, and 1, 2, and 3 years after the procedure. At the 1 year visit, the participant will find out if he/she got the treatment, and if he/she did not, they can choose to cross-over to the treatment if they still meet eligibility criteria.
The purpose of this study is to build a repository (collection) of heart signals from eligible subjects. The experimental part of this study is the collection of heart signals using a device similar to a heart monitor called the Phase Signal Acquisition System. The signals will be electronically sent to a storage center and paired with the subject's heart catheterization results for future use in research and development activities sponsored by Analytics 4 Life. The study will include up to 1500 participants at up to 20 research sites in the United States and will require approximately one hour of the subject's time. There are no follow-up visits. .

The experimental part of this study is the collection of the participant's heart signals using a device similar to a heart monitor called the Phase Signal Acquisition System. The signals will be electronically sent to a storage center, then compared to the results of the participant's heart catheterization and saved for future research and development activities sponsored by Analytics 4 Life. The study will include up to 2500 participants at up to 20 research sites in the United States and will require approximately one hour of the subject's time. There are no follow-up visits.
