Driveline bone anchors and methods of use

1. A bone anchor for securing a driveline to a bone, the driveline connecting an external controller or power source to an implantable blood pump, the bone anchor comprising:

a driveline capture portion configured to receive the driveline and fix a position of the driveline with respect to the driveline capture portion, wherein the driveline capture portion comprises:

a driveline receiver configured to receive the driveline, wherein the driveline receiver comprises a channel sized with respect to a diameter of the driveline to permit the driveline to extend through the channel; and

a driveline anchor configured to engage the driveline to fix the position of the driveline with respect to the driveline receiver; and

a bone capture portion configured to engage a bone and fix a position of the bone capture portion with respect to the bone.

2. The bone anchor of claim 1 , wherein the channel has a diameter less than a diameter of the driveline, and wherein the bone anchor comprises a top, a bottom, a first end, and a second end.

3. The bone anchor of claim 1 , wherein the channel of the driveline receiver is configured to cause the driveline to extend through the channel along an axis that is parallel to a plane formed by the bone capture portion.

4. The bone anchor of claim 1 , wherein the channel is cylindrical or circular, and wherein the driveline is retained within the channel by a friction fit.

5. A system for securing a driveline to a bone via a bone anchor, the driveline electrically connecting an external controller and an implantable blood pump, the system comprising:

an implantable blood pump comprising a rotor and a stator;

an external controller configured to power the implantable blood pump and provide a control signal to the implantable blood pump;

a percutaneous driveline electrically connecting the implantable blood pump and the external controller, wherein the percutaneous driveline has a diameter; and

a bone anchor comprising:

a driveline capture portion configured to receive the driveline and fix a position of the driveline with respect to the driveline capture portion, wherein the driveline capture portion comprises a channel sized with respect to a diameter of the driveline to permit the driveline to extend through the channel; and

a bone capture portion configured to receive a bone and fix a position of the bone capture portion with respect to the bone.

6. The system of claim 5 , wherein the channel having a diameter less than the diameter of the percutaneous driveline.

7. A method for affixing a driveline to a bone, wherein the driveline electrically connects an external controller to an implantable blood pump, the method comprising:

implanting the implantable blood pump in a patient's body;

creating a driveline path through a patient's body, wherein the driveline passes at least one bone;

connecting the driveline to a bone anchor via a driveline capture portion configured to receive the driveline and fix a position of the driveline with respect to the driveline capture portion, wherein the driveline capture portion comprises:

a driveline receiver configured to receive the driveline, wherein the driveline receiver comprises a channel sized with respect to a diameter of the driveline to permit the driveline to extend through the channel; and

a driveline anchor configured to engage the driveline to fix the position of the driveline with respect to the driveline receiver;

connecting the bone anchor to the at least one bone via a bone capture portion configured to engage a bone and fix a position of the bone capture portion with respect to the bone; and

electrically connecting the external controller and the implantable blood pump.

8. The method of claim 7 , wherein connecting the driveline to the bone anchor via the driveline capture portion comprises receiving the driveline in the driveline receiver and fixing the position of the driveline with respect to the driveline receiver via the driveline anchor.

9. The method of claim 8 , wherein the channel comprises a diameter less than a diameter of the driveline.

10. The method of claim 8 , wherein the bone anchor comprises a top, a bottom, a first end, and a second end, and wherein the driveline anchor comprises a plurality of capture hooks.

11. The method of claim 10 , wherein fixing the position of the driveline with respect to the driveline receiver via the driveline anchor comprises inserting the driveline through the plurality of capture hooks, wherein each of the plurality of capture hooks extend towards the top of the bone anchor and are spaced between the first and second ends of the bone anchor.

12. The method of claim 11 , wherein at least some of the capture hooks, together with the driveline receiver define a first channel configured to hold the driveline in a first orientation, and wherein at least one of the capture hooks, together with the driveline receiver defines a second channel configured to hold the driveline in a second orientation.

13. The method of claim 12 , wherein the driveline in the first orientation is perpendicular to the driveline in the second orientation.

14. The method of claim 7 , wherein electrically connecting the external controller and the implantable blood pump comprises providing at least one of: power; or a control signal to the implantable blood pump via the driveline.
