Abstract

In some examples, an anchor for a therapy delivery element includes a body portion including a lumen extending through the body portion. The body portion includes a first configuration in which the lumen is linear, the body portion in the first configuration being configured to receive the therapy delivery element within the lumen. The body portion also includes a second configuration in which the lumen is non-linear, wherein the lumen of the body portion in the second configuration frictionally engages the therapy delivery element.

Claims

1. An anchor for a therapy delivery element, the anchor comprising:

a body portion including a circumferentially closed lumen extending through the body portion, the body portion including;

a first configuration in which the lumen is linear, the body portion in the first configuration being configured to receive the therapy delivery element within the lumen; and

a second configuration in which the lumen is non-linear, wherein the lumen of the body portion in the second configuration frictionally engages the therapy delivery element, wherein the frictional engagement is configured to inhibit movement of the therapy delivery element with respect to the lumen.

2. The anchor of claim 1, wherein a cross-sectional area of the lumen of the body portion in the second configuration is less than a cross-sectional area of at least a portion of the therapy delivery element, such that the body portion in the second configuration compressively engages the therapy delivery element with the therapy delivery element within the lumen.

3. The anchor of claim 1, wherein the body portion includes a first body portion connected by a flexible tab to a second body portion.

4. The anchor of claim 3, wherein the first body portion includes a first lumen extending through the first body portion, and the second body portion includes a second lumen extending through the second body portion, wherein the first lumen is out of alignment with the second lumen with the body portion in the second configuration.

5. The anchor of claim 1, wherein the body portion includes at least one annular rib disposed around the body portion.

6. The anchor of claim 1, comprising at least one retention member associated with the body portion, the at least one retention member configured to attach the anchor to a patient.

7. The anchor of claim 1, wherein the body portion is biased in the second configuration.

8. The anchor of claim 1, wherein the body portion includes an elastomeric material.

9. An anchor for a therapy delivery element, the anchor comprising:

a body portion including a first body portion, a second body portion, and a flexible tab connecting the first body portion and the second body portion, the first body portion including a first circumferentially closed lumen extending through the first body portion, the second body portion including a second circumferentially closed lumen extending through the second body portion, the body portion including;

a first configuration in which the first lumen and the second lumen are substantially aligned, the body portion in the first configuration being configured to receive the therapy delivery element within the first and second lumens; and

a second configuration in which the first lumen is out of alignment with the second lumen, wherein the first and second lumens of the body portion in the second configuration frictionally engage the therapy delivery element, wherein the frictional engagement is configured to inhibit movement of the therapy delivery element with respect to the first and second lumens.

10. The anchor of claim 9, wherein a cross-sectional area of at least one of the first lumen and the second lumen of the body portion in the second configuration is less than a cross-sectional area of at least a portion of the therapy delivery element, such that, with the body portion in the second configuration, at least one of the first body portion and the second body portion compressively engages the therapy delivery element with the therapy delivery element within the first and second lumens.

11. The anchor of claim 9, wherein the flexible tab includes an elastomeric material.

12. The anchor of claim 9, wherein the body portion is biased in the second configuration.

13. The anchor of claim 9, wherein at least one of the first and second body portions of the body portion includes at least one annular rib.

14. The anchor of claim 9, wherein each of the first and second body portions of the body portion includes at least one annular rib.

15. The anchor of claim 9, comprising at least one retention member associated with the body portion, the at least one retention member configured to attach the anchor to a patient.

16. The anchor of claim 15, wherein the at least one retention member is associated with one of the first and second body portions.

17. An anchor for a therapy delivery element, the anchor comprising:

a body portion including a first opening, a second opening, and a circumferentially closed lumen extending through the body portion from the first opening to the second opening, the body portion including;

a first configuration in which the lumen is linear, the body portion in the first configuration being configured to receive the therapy delivery element within the lumen; and

a second configuration in which the lumen is non-linear, wherein the lumen of the body portion in the second configuration frictionally engages the therapy delivery element wherein the frictional engagement is configured to inhibit movement of the therapy delivery element with respect to the lumen.

18. The anchor of claim 17, wherein a cross-sectional area of the lumen of the body portion in the second configuration is less than a cross-sectional area of at least a portion of the therapy delivery element, such that the body portion in the second configuration compressively engages the therapy delivery element with the therapy delivery element within the lumen.

19. The anchor of claim 17, wherein the body portion includes a first body portion connected by a flexible tab to a second body portion, wherein the first body portion includes the first opening and the second body portion includes the second opening.

20. The anchor of claim 19, wherein the first body portion includes a first lumen extending through the first body portion from the first opening to a second opening of the first body portion, and the second body portion includes a second lumen extending through the second body portion from a first opening to the second opening of the second body portion, wherein the first lumen is out of alignment with the second lumen with the body portion in the second configuration.
