Abstract

Systems, methods, and devices for securing a driveline to a bone are disclosed herein. The driveline can connect an external controller to an implantable blood pump. The bone anchor can include a driveline capture portion. The driveline capture portion can receive the driveline and fix a position of the driveline with respect to the driveline capture portion. The driveline capture portion includes: a driveline receiver that can receive the driveline; and a driveline anchor that can engage the driveline to fix the position of the driveline with respect to the driveline receiver. The bone anchor can include a bone capture portion. The bone capture portion can engage a bone and fix a position of the bone with respect to the bone capture portion.

First claim

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; 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 driveline receiver defines an aperture, wherein the aperture 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 - 4 . (canceled)

5 . The bone anchor of claim 2 , wherein the driveline anchor comprises a plurality of capture hooks, and 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.

6 . (canceled)

7 . The bone anchor of claim 5 , 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.

8 . The bone anchor of claim 7 , 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, wherein the driveline in the first orientation is perpendicular to the driveline in the second orientation.

9 . (canceled)

10 . The bone anchor of claim 1 , wherein the bone capture portion comprises at least one of: a screw; a U-bolt a U-channel; or a cable tie.

11 - 13 . (canceled)

14 . The bone anchor of claim 1 , wherein the bone capture portion comprises a first U-member comprising a base and a second U-member comprising a base and a top, wherein the bases of the first and second U-members are connected.

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

16 . The system of claim 15 , wherein the driveline receiver defines an aperture having a diameter less than the diameter of the percutaneous driveline.

17 . The system of claim 15 , wherein the bone capture portion comprises an elongate member and at least one screw extending through a portion of the elongate member.

18 . The system of claim 15 , wherein the bone capture portion comprises an elongate member comprising a first end, a second end, a top, and a bottom, and wherein the bone capture portion comprises a first screw hole proximate to the first end and a second screw hole proximate to the second end.

19 . The system of claim 15 , wherein the bone capture portion comprises a U-shaped elongate member comprising a top, an open bottom, a first end, and a second end, and wherein the driveline capture portion comprises a plurality of capture hooks extending from the top of the U-shaped elongate member, wherein the plurality of hooks comprises a first hook in a first orientation and a second hook in a second orientation, wherein the first and second hooks together with top of the U-shaped elongate member define a first channel configured to hold the driveline in a first orientation.

20 . (canceled)

21 . The system of claim 19 , wherein the driveline capture portion further comprises a third hook in a third orientation, wherein the third hook together with top of the U-shaped elongate member defines a second channel configured to hold the driveline in a second orientation, and wherein the driveline in the first orientation is perpendicular to the driveline in the second orientation.

22 . (canceled)

23 . 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; 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.

24 . The method of claim 23 , 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

25 . The method of claim 24 , wherein the driveline receiver defines an aperture comprising a diameter less than a diameter of the driveline.

26 . The method of claim 24 , 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.

27 . The method of claim 26 , 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.

28 . The method of claim 27 , 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.

29 . (canceled)

30 . The method of claim 28 , wherein the driveline in the first orientation is perpendicular to the driveline in the second orientation.

31 . The method of claim 23 , 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.
