Filter by:The objective of this Study is to evaluate the safety and efficacy of the IN.PACT Admiral® drug coated PTA balloon, utilized for the dilatation of the narrowed sections of the artery, as compared to other standard (non drug coated) PTA balloons. The IN.PACT Admiral, besides the mechanical dilatation effect typical of all PTA balloons, releases a drug (paclitaxel) from the balloon surface into the vessel walls. This drug absorption is intended to limit the chances and the entity of artery re-narrowing over time.
The primary objective of this study is to evaluate the safety and performance of the SAMBA Stent and Delivery System in the treatment of femoropopliteal lesions.
The purpose of this study is to evaluate the safety and activity of two doses of MultiGeneAngio, a cell therapy product produced from the patient's own cells, as potential treatment for patients with chronic critical limb ischemia.
The aim of the study is to compare the diagnostic value of this non-invasive vascular imaging tool with the established vascular diagnostic methods for PAD in order to get prognostic data. A higher sensitivity of Fluorescence angiography in order to recognize progression of critical limb ischemia could lead to earlier therapeutic interventions and thereby increase limb salvage. A diagnostic gap would be closed.
This Clinical Trial is being conducted to study how patients with peripheral arterial disease (a condition in which the blood vessels of the extremities are affected) respond to a dietary regimen of flaxseed. The purpose of the study is to examine whether or not dietary flaxseed have any effect on improving symptoms of cardiovascular disease. Additionally, the effects of dietary flaxseed on exercise tolerance will be assessed.
The purpose of this study is to compare the difference between two magnetic resonance imaging (MRI) techniques for visualizing arteries. The study hypothesizes that one method that relies upon imaging flowing blood in the pelvic and leg arteries will not be as accurate or efficient as injecting a safe imaging agent to change the appearance of the blood on the MRI. Both methods will be compared with Digital Subtraction Angiography (DSA).
The purpose of this study is to investigate the performance of paclitaxel-coated balloon expandable stainless steel coronary stent for the treatment of infrapopliteal stenoses and occlusions in patients with critical limb ischemia compared to percutaneous transluminal balloon angioplasty (PTA).
Lipid-rich atherosclerotic plaques, or "vulnerable plaques" are prone to rupture, causing local intravascular thrombosis, with subsequent grave clinical consequences. Atherosclerotic plaques normally removed during surgery, and peripheral blood samples will be studied to achieve the following objectives: "1" Define histological features of the vulnerable plaque, analyze its physical characteristics, and investigate selected gene expression. "2" Study biomarkers of inflammation in conjunction with the presence of vulnerable plaques. "3" Explore the potential role of infection in atherogenesis.
Critical limb ischemia is a condition where the blood circulation in the limbs, in most cases the legs, is decreased so that pain and non healing wounds ensue. Mostly, this is a sequel of arteriosclerosis and/or diabetes. If surgical and other methods for the improvement of blood supply for the leg have failed or are not possible, most of these patients will proceed to amputation of the leg. Bone marrow contains cells which can induce and augment the growth of new, small arteries called collateral arteries. It has been shown in animals and in some case series that the transplantation of a concentrate of the patient's own bone marrow with stem cells into the ischemic limb can improve the blood circulation via the induction of collateral growth. However, it is not known if this bone-marrow stem cell induced collateral growth is sufficient to avoid otherwise necessary amputations. Therefore, we conduct a study to compare the efficiency of concentrated bone marrow cells injected into the critically ischemic limb compared to a placebo procedure where only saline is injected. We think that the transplantation of autologous bone marrow will reduce the number of necessary leg amputations, reduce pain and induce wound healing. In this investigation, patients with limb threatening ischemia are randomly allocated either to the bone marrow group or to the placebo group. Patients in the bone marrow group will have their bone marrow harvested under sedation, and the bone marrow cells are concentrated. The cell concentrate will then be injected directly into the muscle of the diseased leg. Patients in the placebo group will undergo sedation as well but no bone marrow harvest is done, and saline is injected into the ischemic leg. The procedure will require about 1.5-2 hours, and the subjects will be admitted to a participating vascular Centre. Monthly examinations up to three months after the bone-marrow or placebo procedure are done. After the follow-up of three months, the rate of death and amputations and the wound healing process are compared between groups. Adverse and serious adverse events will be recorded during this time period. Diagnostic studies will be obtained to measure blood flow in the treated leg during the follow up period and include skin oxygen measurements, pressure recordings in the leg and arteriography. Also, quality of life, pain and wound healing will be assessed. After completion of the three months study participation, subjects who have been treated with placebo will be able to receive open-label bone marrow transplantation therapy.
The purpose of this study is to evaluate the safety and activity of increasing doses of MultiGeneAngio, a cell therapy product produced from the patient's own cells, as potential treatment for patients with peripheral arterial disease.
