Abstract

Mammalian body implantable fluid flow influencing device, comprising a modular impeller having: An impeller hub module dimensioned and shaped to be deliverable to a delivery site within a conduit of a conduit system of the mammalian body via a catheter. An impeller vane module having at least a portion of an impeller vane; having, with respect to the impeller hub module, an assembled configuration in which the impeller vane module mates with the impeller hub module, and an unassembled configuration, in which the impeller vane module is unmated with the impeller hub module and being dimensioned and shaped to be deliverable to the delivery site via the catheter when in the unassembled configuration. The modular impeller being formed when the impeller vane module is retained in its assembled configuration, and dimensioned and shaped to be operable within at least one conduit of the conduit system. Method of implantation disclosed.

Claims (42)

1. A modular impeller device configured to be implanted within a body of a patient, the modular impeller device comprising:

an impeller hub;

an impeller vane; and

a control wire configured to be attached to the impeller vane,

wherein the modular impeller device has an assembled configuration in which the impeller vane is mated with the impeller hub, and an unassembled configuration in which the impeller vane is unmated with the impeller hub, the control wire being movable relative to the impeller hub to transition the modular impeller device within the body from the unassembled configuration to the assembled configuration, when the control wire is attached to the impeller vane.

2. The modular impeller device according to claim 1 , wherein the control wire is slidably movable relative to the impeller hub.

3. The modular impeller device according to claim 1 , wherein the impeller hub comprises a passage configured for slidably receiving the control wire therealong.

4. The modular impeller device according to claim 1 , wherein the control wire is configured for being pulled to move the control wire relative to the impeller hub for transitioning the modular impeller device within the body from the unassembled configuration to the assembled configuration.

5. The modular impeller device according to claim 1 , wherein the control wire is further movable relative to the impeller hub to transition the modular impeller device within the body from the assembled configuration to the unassembled configuration, when the control wire is attached to the impeller vane.

6. The modular impeller device according to claim 5 , wherein the control wire is configured for being pushed to move the control wire relative to the impeller hub for transitioning the modular impeller device within the body from the assembled configuration to the unassembled configuration.

7. The modular impeller device according to claim 1 , wherein the control wire is configured for releasably attaching the impeller vane.

8. The modular impeller device according to claim 7 , wherein the modular impeller device, when in the assembled configuration, is configured for being operated when the control wire is released from the impeller hub.

9. The modular impeller device according to claim 1 , wherein the control wire comprises a first magnet, and the impeller vane comprises a second magnet magnetically releasably attachable to the first magnet.

10. The modular impeller device according to claim 1 , wherein the impeller hub comprises an impeller hub connector, and the impeller vane comprises an impeller vane connector configured for releasably connecting to the impeller vane connector.

11. The modular impeller device according to claim 10 , wherein the impeller hub connector comprises a channel, and the impeller vane connector comprises a cylinder portion configured for being slidably received in the channel.

12. The modular impeller device according to claim 11 , wherein the control wire is disposed at least partially along the channel.

13. The modular impeller device according to claim 1 , further comprising a secondary connector configured for releasably retaining the impeller hub and the impeller vane together.

14. The modular impeller device according to claim 1 , further comprising an anchor sized and shaped for surrounding at least partially the impeller hub, the anchor having a collapsed configuration for transcatheter delivery of the modular impeller device within the body, and an expanded configuration configured for anchoring the modular impeller device intravascularly within the body.

15. The modular impeller device according to claim 14 , wherein the control wire passes through an opening of the anchor.

16. The modular impeller device according to claim 15 , wherein the opening of the anchor is sized and shaped for passing the impeller vane therethrough.

17. The modular impeller device according to claim 1 , further comprising a motor unit and a drive shaft operatively connected between the motor unit and the impeller hub for driving the impeller hub.

18. The modular impeller device according to claim 17 , further comprising a control cable extending distally from the motor unit, the control cable having a lumen configured for receiving the drive shaft and the control wire therein.

19. The modular impeller device according to claim 17 , further comprising a control cable extending proximally from the motor, the control cable having a lumen configured for receiving the control wire therein.

20. The modular impeller device according to claim 1 , wherein the control wire is manipulable at a distal end portion thereof by an operator for moving the control wire relative to the impeller hub within the body.

21. The modular impeller device according to claim 20 , wherein the distal end portion is configured to be disposed extracorporeally when the modular impeller device is implanted within the body.

22. The modular impeller device according to claim 1 , wherein the modular impeller device is transcatheterly implantable.

23. The modular impeller device according to claim 1 , wherein the impeller hub and the impeller vane are assemblable together within a cardiovascular system of the patient.

24. The modular impeller device according to claim 1 , wherein the control wire is further configured to be removably attached to the impeller vane, impeller is rotatable only when the control wire is removed from the impeller vane.

25. A modular impeller device configured to be implanted within a cardiovascular system of a patient, the modular impeller device comprising:

an impeller including an impeller hub and an impeller vane;

an anchor configured to at least partially surround the impeller and to anchor the modular impeller device within the cardiovascular system;

and

a control wire configured to be removably attached to the impeller vane, and further configured to be manipulated from outside the cardiovascular system by an operator for the impeller vane to mate with the impeller hub within the cardiovascular system, and for the impeller vane to unmate from the impeller hub within the cardiovascular system when the control wire is attached to the impeller vane.

26. The modular impeller device according to claim 25 , wherein the control wire is further configured for the impeller vane to slidably mate with the impeller hub, and for the impeller vane to slidably unmate from the impeller hub.

27. The modular impeller device according to claim 26 , wherein the impeller is rotatable only when the control wire is removed from the impeller vane.

28. A modular impeller device configured to be implanted within a cardiovascular system of a patient, the modular impeller device comprising:

an impeller hub;

an impeller vane; and

a control wire releasably attachable to the impeller vane,

wherein the modular impeller device has an assembled configuration in which the impeller vane is mated with the impeller hub, and an unassembled configuration in which the impeller vane is unmated with the impeller hub, the control wire being actuatable to transition the modular impeller device within the cardiovascular system from the unassembled configuration to the assembled configuration, when the control wire is attached to the impeller vane.

29. The modular impeller device according to claim 28 , wherein the control wire is slidably actuatable for transitioning the modular impeller device within the cardiovascular system from the unassembled configuration to the assembled configuration.
