Abstract:
1. A method for percutaneously introducing into a body of a living organism a device for circulating a body fluid in the body of the living organism, to support the heart and/or circulation of the living organism, wherein the device comprises: a catheter device which has at least one inlet portion to take up the body fluid at at least one first location within the body of the living organism, at least one outlet portion some distance from the at least one inlet portion to discharge the body fluid at at least one second location some distance from the at least one first location within the body of the living organism and a pump device for directed transport of the body fluid between the at least one inlet portion and the at least one outlet portion of the catheter device, the pump device comprising a collapsible double chamber cavity with an inner chamber and an outer chamber for inserting and feeding the device solely by means of puncturing the skin via a peripheral vein or artery in the living organism; and a valve arrangement coupled to the catheter device for controlled uptake of the body fluid as a function of operation of the pump device at the at least one inlet portion of the catheter device and controlled discharge of the body fluid at the at least one outlet portion of the catheter device, the method comprising the steps of: fitting the outer chamber of the pump device; and after fitting the outer chamber of the pump device, introducing the inner chamber of the pump device by an internal lumen of the catheter device, the internal lumen extending from the outer chamber of the pump device to a location outside of the body of the living organism.
