Driveline bone anchors and methods of use

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.

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.
