Filter by:The objective of this clinical investigation is to demonstrate and provide long term clinical data on safety and performance of the Exist 6F NiTi stent system type FLEX & PULL in a prospective investigation for the treatment of adult patients with de novo or re-stenotic symptomatic atherosclerotic lesions in Peripheral Artery Disease (PAD) requiring treatment of the Superficial Femoral Artery (SFA) or Proximal Popliteal Artery (P1 segment).
Clinical study to investigate the safety and the efficacy of the URECA CTO Device during recanalization and mechanical re-entry into the true lumen after passing the occlusions/calcifications (chronic total occlusions) in the peripheral vasculature.
The purpose of this study is to identify the type of patients being referred for the Vascular Rehabilitation Program (VRP) and to study the success rates of the program according to improvements in walking distance and quality of life surveys. Subjects will be in the VRP for 6-12 weeks and then be followed for 12 months after they complete the program. This is a single-site study at Baylor Scott & White Heart Hospital-Plano.
The purpose of this study is to apply Avazzia micro-current stimulation to patients with chronic, non-healing wounds to determine if this therapy is effective in perfusion and bacterial measurements.
The investigators have developed an online program to help people with peripheral arterial disease (PAD) in their extremities to better self-manage their condition. Some earlier testing has been done and the investigators now wish to try this system with participants who have this blood vessel disease as well as high blood pressure. Investigators are hoping to help these participants to achieve healthier lifestyles and improve their quality of life through education, monitoring and continuing support. A similar online desk-top version with over 30 participants has been tested at St. Michael's Hospital in Toronto. The investigators propose to test this newer mobile system with 210 outpatient participants from Hamilton General Hospital. Data collected will be analyzed following the (12 months for each participant) study, along with data recorded during clinical visits at baseline and twelve months for each participant. The objective is to evaluate changes to participant health and determine whether the health self-management process has been successful in improving participant lifestyles and quality of life, when compared to usual care.
Intermittent claudication (IC), the most common manifestation of peripheral artery disease (PAD), represents not only a significant detriment in quality of life, but also an increased risk for atherosclerotic cardiovascular disease (ASCVD), including progression of PAD, coronary artery disease (CAD) and cerebrovascular disease. Guideline directed therapy for IC includes supervised exercise, smoking cessation and optimal medical management to decrease overall risk of ASCVD. In the VA Health Care System, implementation of supervised exercise therapy through cardiac rehabilitation or physical therapy programs is limited by distances that patients must travel to VA facilities that provide these services. Furthermore, one of the most common failure points in exercise therapy programs is poor patient compliance. Improved patient participation and compliance in exercise programs for IC represents an unmet need, without which the majority of patients with life-style limiting PAD may not be receiving optimal medical management. Small studies have demonstrated the effectiveness of home-based exercise programs as an alternative to supervised exercise therapy; however, the success of the home-based exercise programs require remote coaching and/or regular provider feedback. The wide-spread availability of smart phones and smart devices has accelerated the implementation of telehealth programs that may supplement or may eventually replace in-person encounters for health care delivery. The role of provider feedback in addition to real-time feedback from smart devices remains completely unexplored. Our central hypothesis is that in individuals with IC, regular provider feedback on smart-device-based remote health monitoring data, which is available to the patient in real time, will augment the benefits of home-based exercise programs. We propose a randomized trial in patients with IC to test the central hypothesis through two Specific Aims: 1. To determine the effect of provider feedback on smart-device-based remote health monitoring data during home-based exercise programs on walking distance in patients with IC. 2. To determine the effect of provider feedback on smart-device-based remote health monitoring data during home-based exercise programs on quality of life (QOL) in patients with IC. Based on a sample size calculation to detect a 50% increase in walking distance between the 2 groups, we expect to enroll 30 patients (15 in each group). Patient participation in the study will be concluded after 12 weeks. As an exploratory aim in the study, we will also (as an optional part of the study) collect plasma before and after the 12-weeks of exercise to investigate changes in lipid levels and plasma biomarkers associated with exercise therapy. This exploratory aim will generate preliminary data for future studies.
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 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.
