A device for treating vascular insufficiency is described. The device includes a flexible and elastic tubular structure attached to a base layer. The flexible and elastic tubular structure include an air inlet, where longitudinal expansion of a first portion of the tubular structure is less restricted than radial expansion of the first portion of the tubular structure. A fastener is attached to the base layer and configured to fasten the base layer circumferentially around a limb. A method for treating vascular insufficiency is also described.

A mechanical ventilation system comprises a plurality of ventilation therapy sub-systems. Each of the ventilation therapy sub-systems is adapted to assist a respiratory function of the patient. The system also comprises a detector of the respiratory drive of the patient, an operator interface receiving one or more control parameters, and a main controller. The main controller assigns a therapeutic contribution to each of the ventilation therapy sub-systems based on the respiratory drive of the patient and on the control parameters. The controller modulates the respiratory drive of a patient by controlling each of the plurality of the ventilation therapy sub-systems according to its assigned therapeutic contribution. Distinct ventilation therapy sub-systems may apply negative pressure on the abdomen of the patient, deliver a non-pressurizing inspiratory flow to the patient, or induce a positive pressure in the airways of the patient.
