Endoluminal devices and systems for creating two-way blood flow for the treatment of heart failure
Endoluminal devices are provided for the treatment of heart failure which include a central body adapted to permit the passage of interatrial blood, at least one anchor attached to the central body adapted to keep the endoluminal device in position within a defect present in the atrial septum of a patient's heart, and at least one control element engaged with the central body in a rotating manner. The rotation of the control element in relation to the central body creates a two-way flow of interatrial blood which allows the reduction of high pressure in the right side and in the left side of the heart.
1. An endoluminal device comprising:
a central body adapted to permit the passage of interatrial blood;
at least one anchor attached to the central body adapted to keep the endoluminal device in position within a defect in the interatrial septum of a patient's heart; and
at least one control element engaged with the central body in a rotating manner
wherein the rotation of the control element in relation to the central body creates a two-way flow of interatrial blood wherein the control element consists essentially of a propeller comprising a plurality of rotating vanes attached to each other at the center of the control element, and wherein the central body comprises:
a plurality of fixed vanes attached to the central body at its circumference and attached to each other at the center of the circumference; and
a plurality of apertures configured to alternate with the fixed vanes and adapted to permit the passage of interatrial blood.
2. The endoluminal device of claim 1 , comprising a pair of control elements rotating in opposite directions.
3. The endoluminal device of claim 1 , wherein the number of rotating vanes corresponds to the number of apertures.
4. The endoluminal device of claim 1 , wherein the center of the control element is configured to engage in a rotating manner at the center of the central body.
5. The endoluminal device of claim 1 , wherein the central body comprises a circular rim which extends in a radial direction from the circumference towards the center.
6. The endoluminal device of claim 1 , wherein the central body is cylindrical and is provided with an inner lumen.
7. The endoluminal device of claim 1 , wherein the central body consists essentially of a disc.
8. The endoluminal device of claim 1 comprising a pair of anchors, each attached to one end of the central body.
9. The endoluminal device of claim 1 , wherein the anchor comprises an open link, or a plurality of flanges which extend radially from the central body.
10. The endoluminal device of claim 1 comprising at least one radiopaque marker applied to the anchor.
11. An endoluminal system for the treatment of heart failure, comprising:
the endoluminal device of claim 1 ;
a release catheter for the transport and positioning of the endoluminal device inside the patient's heart;
an electric motor for operating the control element;
an energy transmission device to power the motor;
at least one pressure sensor for the continual measurement of the blood pressure in the right and left atrium;
a control unit for regulating the interatrial two-way blood flow; and
a data transmission device, for data transmission between the sensor, the control unit and motor.
12. The endoluminal system of claim 11 , wherein the motor is an electromagnetic induction electric motor.
