Abstract

The invention features modular implantable ventricular assist devices configured to be, at least in part, assembled within a patient. The devices generally include a pump assembly and an expandable frame. The frame is configured to engage tissue of a patient when implanted. The pump assembly is configured to be operably coupled to the frame when the frame is implanted and in the expanded configuration.

First claim

What is claimed is:

1. A method comprising:
implanting a frame in a vessel;
attaching a scaffold having an opening to the implanted frame;
advancing a pump component through the vessel from a location away from the implanted frame into the scaffold opening; and
operably coupling the pump component to the scaffold.

2. The method of claim 1 , wherein the pump component comprises a micropump.

3. The method of claim 1 , wherein implanting the frame in the vessel comprises engaging the vessel with the frame.

4. The method of claim 1 , wherein the pump component is configured to pump fluid through the frame along a longitudinal axis of the frame.

5. The method of claim 1 , further comprising advancing the frame through the vessel prior to implanting the frame.

6. The method of claim 5 , wherein advancing the frame through the vessel comprises advancing the frame a distance of greater than 50 cm.

7. The method of claim 1 , further comprising advancing the scaffold through the vessel prior to attaching the scaffold to the frame.

8. The method of claim 7 , wherein advancing the scaffold through the vessel comprises advancing the scaffold a distance of greater than 50 cm.

9. The method of claim 1 , wherein advancing the pump component through the vessel comprises advancing the pump component a distance of greater than 50 cm.

10. The method of claim 1 , wherein the frame has an expanded configuration and a collapsed configuration.

11. The method of claim 1 , wherein the scaffold has an expanded configuration and a collapsed configuration.

12. The method of claim 1 , further comprising a heart valve attached to the frame.

13. The method of claim 1 , wherein the vessel is an aorta and the frame is configured to securely engage an inner wall of the aorta when implanted.

14. The method of claim 1 , wherein the frame is configured to be delivered through the vessel via an intravascular catheter.

15. The method of claim 1 , wherein the scaffold is configured to be delivered through the vessel via an intravascular catheter.

16. The method of claim 1 , wherein the pump component is configured to be delivered through the vessel via an intravascular catheter.
