Abstract

There is disclosed various embodiments of an implantable anchor for anchoring a medical lead within a patient. The implantable anchor includes a body having at least one lumen for receiving a medical lead, a cam integrated with the body and rotatable to extend into the lumen for engaging, compressing and twisting the medical lead to inhibit the movement of the lead with respect to the anchor. The body of the anchor may include at least one slot, sized and positioned to receive a portion of the lead to further facilitate the inhibition of the movement of the lead. The cam may include a handle for facilitating the rotation and locking of the cam.

Claims

1. An implantable anchor for anchoring a medical lead within a user, the anchor comprising:

a body having at least a first lumen, the lumen extending from a first end of the body to a second end of the body along an axis, the lumen configured to receive the medical lead, the body having a cavity extending into the body generally perpendicular to the axis of the lumen; and

a cam including a first flange, the cam rotatably mounted within at least portion of the cavity of body intermediate the first end and the second end of the body, the cam rotatable between at least a first position and a second position, such that when the cam is in the first position, the first flange of the cam is substantially free from the lumen, such to facilitate the insertion and movement of the medical lead into the anchor, and further when the cam is in the second position, at least a portion of the flange of the cam extends into the lumen, such that when the medical lead extends through the lumen, the first flange of the cam displaces a section of the medical lead to substantially inhibit the movement of the medical lead with respect to the anchor.

2. The implantable anchor of claim 1, and further including an arm extending from the cam, the arm for facilitating the rotation of the cam between the first and second positions.

3. The implantable anchor of claim 1, further including a locking mechanism for locking the cam in the second position.

4. The implantable anchor of claim 2, wherein the arm includes a portion configured to engage the body to the anchor to releasably lock the cam in the second position.

5. The implantable anchor of claim 4, wherein the cam includes a second flange, the second flange positioned to extend into the lumen, the second flange for displacing the medical lead when the cam is positioned in the second position.

6. The implantable anchor of claim 4, wherein at least a portion of the engagement portion of the arm is configured in generally a “

C”

shape.

7. The implantable anchor of claim 1, wherein said body includes a slot for receiving a portion of the medical lead when the first flange of the cam twists the medical lead.

8. The implantable anchor of claim 1, wherein the body includes a plurality of slots, each of the plurality of slots for receiving a portion of the medical lead when the first flange of the cam displaces the section of the medical lead.

9. An implantable anchor for anchoring a medical lead within a living organism, the anchor comprising:

an elongated body having at least one lumen, the at least one lumen extending intermediate a first end of the body and a second end of the body along an axis, the at least one lumen configured to receive the medical lead, the body having a cavity extending into the body generally perpendicular to the axis of the lumen; and

a cam including at least one flange, with at least a portion of the cam positioned within the cavity of the body, the cam rotatable between at least a first position and a second position, such that when the cam is in the first position, the at least one flange of the cam is substantially free from the lumen, such to facilitate the insertion and movement of the medical lead into the anchor, and further when the cam is in the second position, at least a portion of the flange of the cam extends into the lumen, such that the at least one flange displaces a section of a medical lead extending through the lumen to substantially inhibit the movement of the medical lead with respect to the anchor.

10. The implantable anchor of claim 9, and further including an arm extending from the cam, the arm for facilitating the rotation of the cam between the first and second positions.

11. The implantable anchor of claim 9, further including a locking mechanism for locking the cam in the second position.

12. The implantable anchor of claim 10, wherein the arm includes a portion configured to engage the body to the anchor to lock the cam in the second position.

13. The implantable anchor of claim 9, wherein the cam includes at least a second flange, the second tab positioned to extend into the lumen, the second flange for displacing the section the medical lead when the cam is positioned in the second position.

14. The implantable anchor of claim 12, wherein at least a portion of the engagement portion of the arm is configured in generally a “

C”

shape.

15. The implantable anchor of claim 9, wherein said body includes at least one slot for receiving a portion of the medical lead when the first flange of the cam displaces the section of the medical lead.

16. An implantable anchor for anchoring a medical lead within a living organism, the anchor comprising:

an elongated body having at least one lumen, the at least one lumen extending intermediate a first end of the body and a second end of the body along an axis, the at least one lumen configured to receive the medical lead, the body having a cavity extending into the body generally perpendicular to the axis of the lumen;

a cam connected to the body, the cam rotatable between a first position and a second position; and

a plurality of flanges connected to the cam, such that when the cam is in the first position, each of the plurality of flanges are substantially free from the lumen, such to facilitate the insertion and movement of the medical lead into the anchor, and further when the cam is in the second position, each of the plurality of flanges displaces a section of the medical lead extending through the lumen to substantially inhibit the movement of the medical lead with respect to the anchor.

17. The implantable anchor of claim 16, and further including an arm extending from the cam, the arm for facilitating the rotation of the cam between the first and second positions.

18. The implantable anchor of claim 17, further including a locking mechanism for locking the cam in the second position.

19. The implantable anchor of claim 18, wherein the locking mechanism includes a portion extending from the arm configured to engage the body to the anchor.

20. The implantable anchor of claim 19, wherein said body includes at least one slot for receiving a portion of the medical lead when the plurality of flanges displaces the section of the medical lead.
