View clinical trials related to Peripheral Arterial Disease.
Filter by:The objective is to ensure the pro-active collection of information on quality, safety and performance of FlowOx™ after it is placed on the market. The study will be carried out in a patient population with peripheral artery disease (claudicatio intermittens) to confirm its usefulness and in particular gather information for further improvements of the device related to this patient population. The data collected from the use of the CE-marked FlowOX™ device are change of walking distance, quality of life, and the patient's compliance.
This is an observational study of the DABRA Laser System and other medical devices intended for endovascular treatment of peripheral artery disease.
Different types of stem cells have recently been studied in clinical trial on ischemic disease of the heart and muscular arteries. Adipose derived stem cell, have shown in vitro and in vivo models a stronger potential of success in recovering from ischemic disease and oxygenation of the tissues. The investigators already shown in a phase I study, that adipose derived mesenchymal cells injected in patients with critical limb ischemia and no option for revascularization, had a very good tolerance and interesting effects on skin oxygenation and healing. The aim of the present clinical trial is to confirm the efficacy autologous transplantation of adipose tissue derived mesenchymal cells in patients with critical limb ischemia with poor options or no option for revascularization.
This is a pilot study of a new exercise device (TREDLR) designed to facilitate repetitive ankle flexion/extension movements (i.e., "treadling") through a momentum-driven internal flywheel while seated. The specific goals of this project are to explore improvements in mobility and exercise capacity in individuals who treadle compared to a control group.
An Early Feasibility Study to Assess Safety and Efficacy of the ChampioNIR® SFA Stent in the Treatment of Patients with Femoro-Popliteal Disease
This study investigates the efficacy and safety of the AbsorbaSeal 6Fr Vascular Closure device (VCD) for the closure of access site of patients requiring percutaneous diagnostic or interventional procedures. An expected total of 50 patients will be enrolled in this study. A total of 12 patients (4 patients per site) will be treated as roll-in phase, prior to enrollment of the first patient. The primary objective of this study is to assess the safety and effectiveness of the AbsorbaSeal 6Fr VCD. Enrollment into this study will include anatomically eligible patients requiring diagnostic and interventional procedures. Following physician training, patients will be enrolled. Efficacy and safety analyses will be based on these patients.Patients will be followed procedurally to discharge, at one month, (follow-up commitment). Secondary objectives are to further characterize adverse events (serious and non-serious), clinical utility measures and health-related quality of life.
Prospective, single-center, single-arm, non-randomized study to assess the safety and efficacy of the FLEX Scoring Catheter in patients with atherosclerotic peripheral artery disease in the superficial femoral and popliteal arteries.
The superficial femoral artery (SFA) is frequently involved in atherosclerosis and is the most common target of lower extremity endovascular procedures performed in patients with claudication. Endovascular treatment of SFA is challenging, given its exceptional predisposition to atherosclerosis and its exposure to extreme mechanical forces of extension, compression, torsion and flexion. The SFA is located in a fibro-muscular canal, follows a tortuous course and is considered a 'hostile' location for endovascular procedures, especially stents due to the risk of stent fracture. On the other hand, durability of balloon angioplasty in the SFA is dismal (25% patency at 1 year). Therefore, Nitinol (a metal alloy of nickel and titanium) stent implantation is the mainstay of endovascular SFA interventions when balloon angioplasty (PTA) leads to sub-optimal results during a procedure. It is used in over 70% of all cases and in nearly 100% of all femoro-popliteal (FP) CTO (chronic total occlusions) and long (≥60 mm) interventions. Endovascular treatment of SFA is challenging and restenosis is the most common cause for the lack of durability of a SFA peripheral vascular interventional procedure.5 Restenosis rates of SFA bare metal (nitinol) stents or BMS at 1 year exceeds 50% for lesions ≥60 mm in length or CTO. Stent based treatment of the SFA may not offer any additional advantage for short non-CTO (<60 mm) lesions compared to PTA. In a recent study, primarily comparing drug-eluting stents (DES) to balloon angioplasty in the SFA, 12 month patency rates were 83.1% and 32.8%, respectively for DES and balloon angioplasty arms. However, there are no head-to head studies randomized studies comparing DES and BMS in the SFA. Thus, endovascular SFA intervention in patients with symptomatic PAD is an area of urgent need for high-quality evidence as volume of these procedures continues to rise exponentially in the U.S. and around the world, largely on the basis of insufficient evidence.Thus, the purpose of this study is to conduct a randomized pilot trial comparing DES and BMS for percutaneous revascularization of SFA.
This is a proof-of-concept study to collect images to train a CADe algorithm to predict the correct level of amputation in individuals scheduled for amputation secondary to PAD.
This is a prospective, nonrandomized, single-arm study using CSI Orbital Atherectomy System in patients with PAD (total occlusions or significant stenosis). Patients will be enrolled if they have claudication and/or critical limb ischemia, and identifiable PAD disease with moderate to severe calcification on Computer Tomography Angiogram (PCA) or peripheral angiogram requiring percutaneous peripheral intervention (PPI).
