Abstract
A pumping system (200) for controlling the flow of interatrial blood comprises, housed inside a container (201), a control element (30, 30′, 30″) of the interatrial blood flow. The control element comprises: at least one worm screw (31), the rotation of which creates a two-way flow of interatrial blood; or a pair of counter-rotating propellers (31′); or a pair of membranes (31″) whose deformation creates a two-way flow of interatrial blood; or a flexible structure (31″) whose change in volume within the container (201) creates a two-way flow of interatrial blood.

1-17. (canceled)
A pumping system for the creation of a controlled two-way flow of interatrial blood, comprising:
- a container having an inner lumen suitable for allowing passage of interatrial blood and, at each end, an access opening to a central lumen;
- and
- a control element, engaged in a rotatable manner to the container, suitable for controlling flow of interatrial blood;
- wherein the control element comprises at least a worm screw, housed inside the container, the rotation of which creates a two-way flow of interatrial blood.
A pumping system for the creation of a controlled two-way flow of interatrial blood, comprising:
- a container having an inner lumen suitable for allowing passage of interatrial blood and, at each end, an access opening to a central lumen;
- and
- a control element engaged in a rotatable manner to a central body, suitable for controlling flow of interatrial blood;
- wherein the control element comprises a pair of counter-rotating propellers, each housed in an opening, the rotation of which creates a two-way flow of interatrial blood, and wherein each propeller comprises a plurality of blades.
A pumping system for the creation of a controlled two-way flow of interatrial blood, comprising:
- a container having an inner lumen suitable for allowing passage of interatrial blood and, at each end, an access opening to a central lumen;
- and
- a control element, engaged to the container, suitable for controlling flow of interatrial blood;
- wherein the control element comprises a pair of membranes, each positioned at an opening and each fitted with a one-way valve, the deformation of which creates a two-way flow of interatrial blood.
A pumping system for the creation of a controlled two-way flow of interatrial blood, comprising:
- a container having an inner lumen suitable for allowing passage of interatrial blood and, at each end, an access opening to a central lumen;
- and
- a control element, engaged to the container, suitable for controlling flow of interatrial blood;
- wherein the control element comprises a flexible structure positioned inside the container, and a pair of membranes provided at the openings of the container, each fitted with a one-way valve, wherein the actuation of a flexible membrane leads to a change in volume inside the container and the creation of a two-way flow of interatrial blood.
