Abstract: The present invention relates to a non-invasive pulsatile circulatory assistance device encouraging the circulation of a volume of blood in a subject's body, wherein the device includes a flexible multilayer structure for applying against at least a portion of the subject's body, the structure having a flexible inner layer beside the subject's body and a more rigid outer layer; means for pulsating connected to the multilayer structure in such a manner that the assembly having the structure plus the pulsation means is leaktight, and wherein the pulsation means are adapted to create pulsations between the inner and outer layers by means of a fluid referred to as a “pulsation” fluid, each of the pulsations propagating progressively in the venous return direction along the portion of the subject's body when the structure is placed on the portion of the subject's body.

Abstract: The present invention pertains to the field of medical devices and in particular to a circulatory flow restoration (CFR) device comprising an abdominal pressure element, a thoracic pressure element, and a pulsatile generator. The present circulatory flow restoration (CFR) device may be used in cases of cardiac arrest.

Abstract: The present disclosure relates to a therapeutic method for improving the hemodynamics, the overall microcirculation in organs, and the restoration and preservation of deficient endothelial function in a patient, the method includes maintaining blood circulation in the patient's veins and arteries and temporarily relieving the heart of its pumping function. Relief may be accomplished by increasing the preload of the right ventricle so as to improve oxygenation of the myocardium and its contractility, reducing and diffusing regular pulsations in the proximity of the aortic root so as to improve the hemodynamics of the left ventricle of the heart, and/or mechanically stimulating the endothelium by shear forces so as to reduce systemic and pulmonary afterload.

Abstract: The invention relates to a single-use device, intended to be used in surgery each time a vascular approach by cannulation or catheterization (extracorporeal circulation, anesthesia, emergency, intensive care) is found to be necessary, in particular in heart surgery or interventional cardiology. This new device essentially includes a body (5), a sealing system consisting of two inflatable disks (4), a control connector for inflating and deflating the disk (4), a tubular unit (6) and a flexible guide (1).

Abstract: The invention relates to a novel pulsating medical device comprising: a catheter (1) designed to be inserted into a blood vessel, having a diameter and comprising a rod at its insertion end, termed part A; and an inflatable component (6) housed around part of the catheter (1), termed part B, said inflatable component (6) being designed to be connected to an inflation means (9) connected to the other end of said catheter (1) and termed part C, so that said inflatable component can be inflated/deflated in a pulsed manner, the diameter of part B of said catheter (1) being less than the diameters of parts A and C of said catheter (1), and the diameters of parts A and C of said catheter (1) being approximately equal.
