    摘要: A catheter directionally conducts a pulsating body fluid and has a line segment defining an inner volume. A pump chamber section is arranged proximally as an extension of the line segment and defines a pump chamber having a frame therein accommodating a balloon. A first opening connects the inner volume to an external volume and a second opening is arranged proximally from the first opening to connect the inner volume to the external volume. A check valve is assigned to the second opening and the check valve includes a valve foil having an aperture formed therein offset from the second opening. A third opening communicates with the pump chamber. The frame is of a shape memory material which provides rigidity for a pulsatile operation of the balloon. During operation, the pulsating body fluid is conveyed in the inner volume directionally between the first and second opening by operating the balloon.

    摘要: A pump catheter for the directed pulsatile conduction of blood includes a proximal section and a distal section which has an expandable pump chamber and a tube section arranged distally from the pump chamber. The tube section has an outlet opening. An inlet element having at least one inlet opening is arranged between the proximal section and the pump chamber and the inlet element and the pump chamber are geometrically spaced apart by a coupling element.

    摘要: The invention relates to a catheter for the directional conductance of a body fluid, particularly blood. The catheter includes a line segment which has a film tube defining an inner volume. A first port connects the inner volume to an external volume and a second port, arranged distally from the first port, connects the inner volume with the external volume. During operation of the catheter, the body fluid is conducted in the inner volume directionally between the first and second ports. The line segment includes a reinforcement running in the interior of the film tube. The film tube has a foldable section, a connecting region whereat the film tube is connected to the reinforcement, and a stabilized section having a structured profile.
