Abstract

Systems, methods, and devices for securing a driveline to a portion of skin are disclosed herein. The driveline can connect an external controller to an implantable blood pump. The skin 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 skin anchor can include a force distribution portion. The force distribution portion can engage a portion of skin and fix a position of the portion of skin with respect to the force distribution portion.

First claim

1 . A skin anchor for securing a percutaneous driveline to a portion of skin, the driveline connecting an external controller or power source to an implantable blood pump, the skin 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 force distribution portion extending from the driveline and configured to engage a portion of the skin and fix a position of the force distribution portion with respect to the portion of the skin.

2 . The skin anchor of claim 1 , wherein the force distribution portion comprises an enlarged member having a diameter larger than a diameter of the driveline and radially extending from the driveline when the driveline is received within the driveline capture portion.

3 - 4 . (canceled)

5 . The skin anchor of claim 1 , wherein the driveline receiver defines an aperture configured to receive the driveline, wherein the aperture has a diameter less than a diameter of the driveline.

6 . (canceled)

7 . The skin anchor of claim 5 , wherein the aperture comprises an interior surface, and wherein the interior surface comprises at least one feature configured to resist displacement of the skin anchor along the driveline.

8 - 18 . (canceled)

19 . The skin anchor of claim 1 , further comprising a tunneling bullet located intermediate between the driveline capture portion and the external controller, wherein the tunneling bullet comprises a base portion and a tip portion, and wherein the base portion abuts the force distribution portion, and wherein the tunneling bullet comprises a diameter of the base portion, wherein the diameter of the base portion is greater than the diameter of the force distribution portion.

20 - 21 . (canceled)

22 . The skin anchor of claim 1 , wherein the force distribution portion comprises a plurality of radially extendable tendrils.

23 . The skin anchor of claim 22 , wherein each of the radially extendable tendrils comprises a first arcuate component oriented in a first direction and a second arcuate component oriented in a second direction, wherein the first direction is opposite the second direction, wherein each of the radially extendable tendrils comprises the first arcuate component contacting the second arcuate component.

24 . (canceled)

25 . A system for securing a driveline to a portion of skin via a skin 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 skin 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 force distribution portion extending from the driveline and configured to engage a portion of the skin and fix a position of the force distribution portion with respect to the portion of the skin.

26 . The system of claim 25 , wherein the force distribution portion comprises an enlarged member, having a diameter larger than a diameter of the driveline, and wherein the enlarged member radially extends from the driveline when the driveline is received within the driveline capture portion.

27 - 28 . (canceled)

29 . The system of claim 25 , wherein the driveline receiver defines an aperture having a diameter less than a diameter of the driveline and configured to receive the driveline, and wherein the aperture comprises an interior surface comprising at least one feature configured to engage the driveline to fix the driveline with respect to the skin anchor.

30 - 38 . (canceled)

39 . The system of claim 25 , further comprising a tunneling bullet intermediate between the driveline capture portion and the external controller wherein the tunneling bullet comprises a base portion and a tip portion, and wherein the base portion abuts the force distribution portion.

40 . (canceled)

41 . The system of claim 39 , wherein the tunneling bullet comprises a first diameter at the base portion, wherein the diameter of the base portion is greater than the diameter of the force distribution portion, and wherein the tunneling bullet tapers from the first diameter at the base portion to a second diameter at the tip portion, wherein the second diameter is smaller than the first diameter.

42 . The system of claim 25 , wherein the force distribution portion comprises a plurality of radially deployable tendrils.

43 . The system of claim 42 , wherein each of the radially deployable tendrils comprises a first blade oriented in a first direction and a second blade oriented in a second direction, wherein each of the first and second blades comprise a pair of ends and an arcuate component located between the pair of ends, wherein the first direction is opposite the second direction, and wherein the arcuate component of the first blade abuts the arcuate component of the second blade.

44 . A method for affixing a driveline to a portion of skin, 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; connecting the driveline to a skin 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 skin anchor to a portion of skin proximate to a port through which the driveline exits the patient's body via a force distribution portion extending from the driveline and configured to engage a portion of the skin; and electrically connecting the external controller and the implantable blood pump.

45 . The method of claim 44 , wherein the force distribution portion comprises an enlarged member radially extending from the driveline, and wherein connecting the skin anchor to the portion of skin proximate to the port through which the driveline exits the patient's body comprises subdermally positioning the force distribution adjacent to the portion of skin proximate to the port.

46 . (canceled)

47 . The method of claim 45 , wherein the enlarged member has a diameter that is at least one of: larger than the port; or larger than a diameter of the driveline.

48 . (canceled)

49 . The method of claim 44 , wherein connecting the driveline to the skin anchor via the driveline capture portion comprises receiving the driveline in the driveline receiver and fixing the position of the driveline with respect t
