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 a cavity for receiving a medical lead, and a separate, removable key for insertion into the cavity. The key, upon insertion into the cavity, engages and locks the medical lead into place and prevents the movement of the medical lead with respect to the anchor.

Claims

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

a base having a cavity, the cavity for receiving the medical lead;

a key having a first portion for insertion into the cavity of the base, the first portion having a shape to mate with at least a portion of the cavity of the base;

wherein when the medical lead is disposed in the cavity of the base and the first portion of the key is subsequently inserted into the cavity of the base, the key engages at least a portion of the lead and inhibits the movement of the medical lead with respect to the anchor.

2. The implantable anchor of claim 1, further including a first hole extending through the base and a second hole extending through the first portion of the key, such that when the medical lead is disposed in the cavity of the base and the first portion of the key is inserted into the cavity of the base, the first hole and the second hole being in alignment to receive a suture therethrough to secure the anchor to the user and to further secure the first portion of the key in the cavity of the base.

3. The implantable anchor of claim 1, further including a first hole extending through the base, the first hole to facilitate the suturing of the anchor to the user.

4. The implantable anchor of claim 1, wherein each of the key and the base include a groove, such that then the first portion of the key is inserted into the cavity of the base, the groove of the key is in alignment with the groove of the base, the groove of the base and the key to receive a suture for securing the key to the base.

5. The implantable anchor of claim 1, wherein the cavity is configured to receive a second medical lead, the anchor further including a second key, the second key having a first portion for insertion into the cavity of the base, the first portion of the second key having a shape to mate with at least a portion of the cavity of the base, wherein when the second medical lead is disposed in the cavity of the base and the first portion of the second key is subsequently inserted into the cavity of the base, the key engages at least a portion of the second medical lead and inhibits the movement of the second medical lead with respect to the anchor.

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

a base having a cavity, the cavity for receiving the medical lead;

a first key having a portion for insertion into the cavity of the base;

wherein when the medical lead is disposed in the cavity of the base and the portion of the first key is subsequently inserted into the cavity of the base, the first key engages at least a portion of the medical lead and inhibits the movement of the medical lead with respect to the anchor.

7. The implantable anchor of claim 6, further including a first hole extending through the base, the first hole to facilitate the suturing of the anchor to the user.

8. The implantable anchor of claim 7, further including a second hole extending through the key, such that when the medical lead is disposed in the cavity of the base and the key is inserted into the cavity of the base, the first hole and the second hole align to receive a suture therethrough to secure the anchor to the living organism and to further secure the key within the cavity of the base.

9. The implantable anchor of claim 6, wherein each of the key and the base include a groove, such that then the key is inserted into the cavity of the base, the groove of the key is in alignment with the groove of the base, the groove of the base and the key to receive a suture for securing the key to the base.

10. The implantable anchor of claim 8, wherein each of the key and the base include a groove, such that then the key is inserted into the cavity of the base, the groove of the key is in alignment with the groove of the base, the groove of the base and the key to receive a suture for securing the key to the base.

11. The implantable anchor of claim 10, wherein the cavity is configured to receive a second medical lead, the anchor further including a second key, the second key having a portion for insertion into the cavity of the base, wherein when the second medical lead is disposed in the cavity of the base and the second key is subsequently inserted into the cavity of the base, the second key engages at least a portion of the second medical lead and inhibits the movement of the second medical lead with respect to the anchor.

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

a base having a cavity, the cavity for receiving the medical lead;

a first separate key having a portion for insertion into the cavity of the base;

the base further including a first opening for receiving the first key, the base including a second opening and third opening, with the second opening and the third opening configured to facilitate the passing of the medical lead therethrough;

wherein when the medical lead passes through the second and third opening and is disposed in the cavity of the base, when the portion of the first key is subsequently inserted into the cavity of the base, the first key engages at least a portion of the medical lead and inhibits the movement of the medical lead with respect to the anchor.

13. The implantable anchor of claim 12, further including a first hole extending through the base, the first hole to facilitate the suturing of the anchor to the user.

14. The implantable anchor of claim 13, further including a second hole extending through the key, such that when the medical lead is disposed in the cavity of the base and the key is inserted into the cavity of the base, the first hole and the second hole align to receive a suture therethrough to secure the anchor to the living organism and to further secure the key within the cavity of the base.

15. The implantable anchor of claim 12, wherein each of the key and the base include a groove, such that then the key is inserted into the cavity of the base, the groove of the key is in alignment with the groove of the base, the groove of the base and the key to receive a suture for securing the key to the base.

16. The implantable anchor of claim 14, wherein each of the key and the base include a groove, such that then the key is inserted into the cavity of the base, the groove of the key is in alignment with the groove of the base, the groove of the base and the key to receive a suture for securing the key to the base.

17. The implantable anchor of claim 15, wherein the cavity is configured to receive a second medical lead, the anchor further including a second key, the second key having a portion for insertion into the cavity of the base, wherein when the second medical lead is disposed in the cavity of the base and the second key is subsequently inserted into the cavity of the base, the second key engages at least a portion of the second medical lead and inhibits the movement of the second medical lead with respect to the anchor.
