Filter by:The aim of the study is to assess the safety and efficacy of the paclitaxel-releasing balloon catheter SeQuent® Please OTW to treat de novo and restenotic lesions in peripheral arteries. It is the intention of this trial to treat suitable target lesions with drug coated balloon (DCB) only.
A study to assess the effect of negative pulsating pressure therapy on patients with impaired blood flow to the leg caused by arterial disease, to see if the FlowOx device will increase the blood flow to the leg in these patients.
The primary purpose of this Phase 2 study is to optimize Plasmin delivery by comparing different delivery regimens in patients with peripheral arterial occlusion. The study includes a blinded plasminogen activator treatment group and a blinded plasminogen activator placebo group. The study will also assess safety and tolerability of Plasmin at 150 and 250 mg doses.
The objective of the study is To verify the safety and efficacy of the MDT-4107 Drug-Eluting Coronary Stent in the treatment of de novo lesions in native coronary arteries with a reference vessel diameter (RVD) that allows the use of 2.25mm diameter stents.
Arteriosclerosis is a common chronic disease with well known risk factors like diabetes mellitus, hypertension, dyslipidemia, adipositas and smoking, leading to severe complications like myocardial infarction, stroke or peripheral arterial occlusive disease. In addition to life-style factors there is also a genetic predisposition to develop complicated atherosclerosis. Objective: Improve individual risk prediction by clinical phenotyping and genotyping.
The objective of this study is to compare remote superficial femoral artery endarterectomy with suprageniculate bypass surgery in the treatment of long occlusions of the superficial femoral artery. The study hypothesis is that patency rates are comparable and therefore the minimal invasive remote superficial femoral artery endarterectomy can be considered in patients presenting with a long occlusion of the superficial femoral artery.
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 Thunder Trail is a randomized , double-blinded, placebo controlled German multi-centre study on the efficacy of local paclitaxel for prevention of restenosis in the superficial and popliteal artery.
The Rio Study is a randomized, double blinded German- Swiss- Austria multi-centre trial on the efficacy and safety of ReoPro together with interventional recanalization of TASC D lesions in the SFA and popliteal artery.
