Peripheral Arterial Occlusive Disease
Peripheral Arterial Occlusive Disease (PAOD) is a condition caused by ischemia in the legs due to atherosclerotic disease affecting the larger arteries of the legs. Chronic PAOD can be regarded as a marker of generalized atherosclerosis. PAOD threatens the survival of an extremity and often causes lifelong disablement from a painful leg. The clinical consequences of PAOD include pain on walking (claudication), pain at rest and loss of tissue integrity in the distal limbs.A variety of medical therapies have been investigated for patients with PAOD. There is currently no evidence to suggest that any medical therapy is effective for patients with rest pain and/or ischemic ulcers. Also, the use of intramuscular angiogenic VEGF-A gene transfer has recently demonstrated a improvement in clinical and hemodynamic status in patients with severe PAOD
Severe Peripheral Artery Occlusive Disease
This is the first clinical research trial in which intravenous Prostaglandin E1 (PGE1 is a vasoactive hormone) will be used as supportive treatment along with the angioplasty procedure to treat or open up a blocked artery within one lower limb or the most affected of two limbs in subjects with Peripheral Arterial Occlusive Disease.
Peripheral Vascular Disease
Peripheral artery disease (PAD) results in blockages of arteries (blood vessels) in the legs and decreased blood flow to the legs. This may cause difficulty or pain with walking or other activities that use leg muscles. Exercise may help improve blood flow in the legs and improve the ability to walk. This research project is being implemented in adults with PAD to examine the effects of exercise or weight loss programs on lower extremity blood flow, health, and physical function.

Peripheral Arterial Occlusive Disease
The purpose of this study is to test the effects of leg exercise assistive paddling (LEAP) therapy during prolonged sitting (PS) on vascular and functional performance in those with peripheral artery disease (PAD) and age-matched controls. LEAP therapy is a novel application of passive limb movement to enhance blood flow through the legs without muscular contractions. Specifically, LEAP therapy is the rotational passive movement of the lower leg about the knee from 90 to 180 degrees of rotation at a cadence of 1Hz. Previous literature has indicated that this movement pattern can produce robust increases in blood flow in the passively moved limb in healthy individuals, and passive limb movement may protect vascular function during PS. However, the impact of LEAP therapy to improve blood flow in the legs of those with PAD during PS is unknown. Participants will participate in a randomized cross-over design study with 2 visits (LEAP therapy and no LEAP therapy). For the first visit, participants will be randomly allocated to receive LEAP therapy during 2.5 hours of PS or not. For the second visit, participants will sit for 2.5 hours and will receive the condition that they did not previously receive. Before and after PS, the following measurements will be made: flow-mediated dilation of the popliteal and brachial arteries, arterial stiffness with tonometry techniques, microvascular vasodilatory capacity and skeletal muscle metabolic rate with near-infrared spectroscopy, autonomic nervous system function, and there will be blood drawn from the antecubital vein. After PS, participants will participate in a graded exercise test to assess functional walking capacity. Finally, during PS, near-infrared spectroscopy on the calf muscles and electrocardiogram will be collected continuously to monitor muscle oxygen availability and autonomic activity, respectively.

Peripheral artery disease (PAD) is associated with elevated oxidative stress, and oxidative stress has been implicated as the cause of reduced endothelial reactivity in individuals with PAD. Endothelial function is important because the endothelium contributes to the dilation of arteries during exercise, thereby implicating impaired endothelial function as a mechanism contributing to exacerbated exercise-induced ischemia. Therefore, the purpose of this study is to test the hypothesis that acute exogenous diroximel fumarate (Vumerity) intake will improve antioxidant capacity, thereby reducing oxidative stress and improving vascular function and walking capacity in those with PAD. During this study, participants will be administered diroximel fumarate or a placebo, and the acute effects of diroximel fumarate on vascular function and walking capacity will be assessed. Vascular function and walking capacity will be assessed with flow-mediated dilation, arterial stiffness, head-up tilt test, blood biomarkers, near-infrared spectroscopy, and a treadmill test. There will be a follow-up visit to assess blood work after diroximel fumarate.

The purpose of this study is to determine if the CROSSER CTO Recanalization System can facilitate the successful crossing of Chronic Total Occlusions in the Central lumen of the Superficial Femoral Artery (SFA). A Chronic Total Occlusion (CTO) is defined as 100% narrowing of the artery, with no angiographically detectable antegrade blood flow, and the assessment that the lesion has been in existence for a minimum of 30 days. This study will enroll up to 100 patients at up to 8 clinical sites. The CROSSER CTO Recanalization System was cleared for commercialization by the US Food \& Drug Administration. This study also involves an imaging device called the IVUS (Intravascular Ultrasound Imaging) catheter. This device has been cleared for commercialization by the US Food and Drug Administration and will be studied for its cleared intended use. The IVUS catheter is used to generate real-time images of the artery, which will allow for evaluation of the artery after the occlusion is crossed. This is a post-market registry.

The goal of this observational study is to identify which plaque lesions in patients with peripheral arterial disease are impenetrable and to determine which devices minimize vessel wall injury. Patients undergoing intervention will have an MRI scan prior to their planned percutaneous vascular intervention to assess the plaque and predict procedural difficulty. Patients undergoing lower limb amputation due to peripheral arterial disease will have their limbs included into a second arm of the study The limb will undergo an MRI scan to assess the plaque. The investigator will then test two different devices and assess the effects of these devices on the vessel wall.
