Intermittent Negative Pressure; Impact on Peripheral Artery Disease and Intermittent Claudication

2019-09-27 06:30:42 | BioPortfolio


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.


A multi-center, randomized, sham (placebo)-controlled, double-blind trial to assess the efficacy and safety of FlowOx. This is done by comparing the increase in pain free walking distance compared to sham (placebo) device in patients with peripheral arterial disease (PAD) and intermittent claudication.

This study is conducted to assess the efficacy and safety of FlowOx™ compared to a sham FlowOx™ (placebo) device treatment. FlowOx™ can provide intermittent negative pressure (up to - 40 mmHg INP [intermittent negative pressure]) which is known to improve blood flow. The same device will also work as a sham (placebo) device by less negative pressure exerted by the device (in the range of -10 mmHg).

Daily home use of FlowOx™ for 2 hours (divided into minimum two sessions of 1 hour) per day in PAD-patients with intermittent claudication (stage II EMA, equivalent to Fontaine stage IIb in Germany) relative to sham (placebo) will be provided over a period of 12 weeks.

This efficacy study is evaluating the clinical effects of INP on patient with intermittent claudication with special focus on changes in pain free walking distance and quality of life.

Medical and Biotech [MESH] Definitions

An ergot derivative that has been used as a cerebral vasodilator and in peripheral vascular disease. It has been suggested to ameliorate cognitive deficits in cerebrovascular disease.

Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 blocking activity. It is effective in the prophylaxis of migraine, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an adjuvant in the therapy of epilepsy.

A beta-adrenergic agonist that causes direct relaxation of uterine and vascular smooth muscle. Its vasodilating actions are greater on the arteries supplying skeletal muscle than on those supplying skin. It is used in the treatment of peripheral vascular disease and in premature labor.

A nonselective alpha-adrenergic antagonist. It is used in the treatment of hypertension and hypertensive emergencies, pheochromocytoma, vasospasm of RAYNAUD DISEASE and frostbite, clonidine withdrawal syndrome, impotence, and peripheral vascular disease.

Extracellular membrane vesicles generated by the shedding of CELL MEMBRANES blebs. Microparticles originating from PLATELETS; ENDOTHELIAL CELLS; and other cell types circulate in the peripheral blood and through the MICROVASCULATURE where larger cells cannot, functioning as active effectors in a variety of vascular processes such as INFLAMMATION; HEMOSTASIS; angiogenesis; and vascular reactivity. Increased levels are found following stimulation of bleb formation under normal or pathological conditions.
