Summary

This study is asking for volunteers who have been diagnosed with acute pulmonary embolism (PE). PE is a blood clot that blocks and stops blood flow to an artery in the lung. PE usually results from a blood clot in the leg that travels to the lung. Patients with PE may have shortness of breath, chest pain and/or an irregular heartbeat. This study will use a device known as the Vertex Pulmonary Embolectomy System. The Vertex Pulmonary Embolectomy System is a medical device which is indicated for use in the pulmonary arteries for the non-surgical removal of blood clots from blood vessels. The Vertex System has not yet been approved for use by the Food and Drug Administration (FDA) but is approved for use in this study for PE removal. Your study doctor will inform you about the risks that are related to your PE procedure. The risks associated with the study include loss of confidentiality and unknown risks. There will be no benefit to you, but it is hoped the information gained will add to the understanding of treatment options for others in the future. You do not have to participate to have your condition treated. This study will take 30 days to complete.

Hypertension/ High Blood Pressure
Summary

This study will enroll two groups of participants. The first group are those who participated in the RADIANCE CAP study, so have already undergone the renal denervation procedure. Those participants can enroll in this post approval study which will entail yearly follow up visits or telephone calls, blood pressure monitoring and questionnaires. The second group of participants are those scheduled to undergo a procedure called renal denervation for the treatment of high blood pressure that has not responded adequately to medications and lifestyle changes. Renal denervation is a procedure which uses a catheter (thin hollow tube) placed in the renal arteries (blood vessels that go to the kidneys) to deliver ultrasound energy. This energy will heat up a small area of tissue around the renal arteries to disable nerves that are surrounding the blood vessels as a way to help reduce blood pressure. Study visits include screening, procedure, discharge, months 1, 3, 6 and 12 then yearly for up to 5 years. Study procedures for this group includes blood work and urine studies, blood pressure monitoring, questionnaires, a follow up ultrasound of your kidneys and the blood vessels around the kidneys. Study related risks include loss of confidentiality, blood draw risks and unknown risks.

Pulmonary Artery Denervation Clinical Study using the Gradient Denervation System in Heart Failure Patients with Pulmonary Hypertension Group 2

Summary

This study is for patients who have heart failure with pulmonary hypertension. Heart failure means that the heart cannot pump blood as well as normal. Pulmonary hypertension happens when the pressure in the blood vessels leading from the heart to the lungs is too high, blood flowing through the lungs is limited, and the pressure in the lungs increases when you are physically active, causing symptoms of shortness of breath and tiredness.

The study uses the Gradient device to see if can help treat heart failure with pulmonary hypertension. This device and therapy is still investigational, which means it is currently not approved by a regulatory agency (such as U.S Food and Drug Administration) for regular hospital use and it includes only individuals who choose to take part. Risks in this study include those for standard cardiac catheterization techniques and the administration of anesthesia including allergic reactions, low blood pressure, skin rash, or difficulty breathing; however, all of the risks may not be known. The study will last approximately 3 years and includes the following visits: Baseline/Screening, Procedure, Discharge, 1 month, 6 months and visits annually for 3 years. Study related procedures include a physical exam, blood testing, 6 minute walk test, echocardiogram, CT scan and a Right heart catheterization.
