Abstract

A lead receptacle having a lumen configured to traverse from an outer side of an outermost intercostal muscle to an inner side of an innermost intercostal muscle of an intercostal space of a patient and to support a lead traversing through the lumen. The lumen being configured to support one or more cardiac leads traversing through the intercostal space.

Claims

1. A lead receptacle comprising:

a lumen configured to traverse from an outer side of an outermost intercostal muscle to an inner side of an innermost intercostal muscle of an intercostal space of a patient and to support a lead traversing through the lumen, wherein the lumen is configured to support one or more cardiac leads traversing through the intercostal space and is configured to be screwed into an intercostal muscle of the patient within the intercostal space.

2. The lead receptacle of claim 1, wherein the lumen comprises an electrically insulating material configured to inhibit traversal of electrical signals through walls of the lumen.

3. The lead receptacle of claim 1, wherein the intercostal space of the patient is the intercostal space associated with a cardiac notch of the left lung of the patient.

4. The lead receptacle of claim 1, wherein the proximal end of the lumen is configured to terminate adjacent the pleural space of the patient.

5. The lead receptacle of claim 1, wherein the proximal end of the lumen is configured to terminate in the mediastinum of the patient.

6. The lead receptacle of claim 1, wherein the one or more cardiac leads are configured to carry electrical stimulation therapy from a pulse generator to a heart of the patient.

7. The lead receptacle of claim 1, wherein the lumen is coated with a pharmacological agent.

8. A lead receptacle comprising:

a lumen configured to traverse from an outer side of an outermost intercostal muscle to an inner side of an innermost intercostal muscle of an intercostal space of a patient and to support a lead traversing through the lumen, wherein the lumen is configured to support one or more cardiac leads traversing through the intercostal space and wherein the lumen is fixed into the intercostal space using a tine, a hook, a spring, or a screw.

9. The lead receptacle of claim 8, wherein the lumen comprises an electrically insulating material configured to inhibit traversal of electrical signals through walls of the lumen.

10. The lead receptacle of claim 8, wherein the intercostal space of the patient is the intercostal space associated with a cardiac notch of the left lung of the patient.

11. The lead receptacle of claim 8, wherein the proximal end of the lumen is configured to terminate adjacent the pleural space of the patient.

12. The lead receptacle of claim 8, wherein the proximal end of the lumen is configured to terminate in the mediastinum of the patient.

13. The lead receptacle of claim 8, wherein the lumen is configured to be pushed into an intercostal muscle of the patient within the intercostal space.

14. The lead receptacle of claim 8, wherein the one or more cardiac leads are configured to carry electrical stimulation therapy from a pulse generator to a heart of the patient.

15. The lead receptacle of claim 8, wherein the lumen is coated with a pharmacological agent.

16. A lead receptacle comprising:

a lumen configured to traverse from an outer side of an outermost intercostal muscle to an inner side of an innermost intercostal muscle of an intercostal space of a patient and to support a lead traversing through the lumen, wherein the lumen is configured to support one or more cardiac leads traversing through the intercostal space; and

a septum disposed transversely within the lumen, the septum configured to form a seal around the lead traversing through the lumen.

17. The lead receptacle of claim 16, wherein the lumen comprises an electrically insulating material configured to inhibit traversal of electrical signals through walls of the lumen.

18. The lead receptacle of claim 16, wherein the intercostal space of the patient is the intercostal space associated with a cardiac notch of the left lung of the patient.

19. The lead receptacle of claim 16, wherein the proximal end of the lumen is configured to terminate adjacent the pleural space of the patient.

20. The lead receptacle of claim 16, wherein the proximal end of the lumen is configured to terminate in the mediastinum of the patient.

21. The lead receptacle of claim 16, wherein the lumen is configured to be pushed into an intercostal muscle of the patient within the intercostal space.

22. The lead receptacle of claim 16, wherein the one or more cardiac leads are configured to carry electrical stimulation therapy from a pulse generator to a heart of the patient.

23. The lead receptacle of claim 16, wherein the lumen is coated with a pharmacological agent.

24. A lead receptacle comprising:

a lumen configured to traverse from an outer side of an outermost intercostal muscle to an inner side of an innermost intercostal muscle of an intercostal space of a patient and to support a lead traversing through the lumen, wherein the lumen is configured to support one or more cardiac leads traversing through the intercostal space; and

a second lumen configured to traverse from an outermost side of an outermost intercostal muscle to an innermost side of an innermost intercostal muscle, the second lumen adapted to facilitate dispensing pharmacological agents into the thorax of the patient.

25. The lead receptacle of claim 24, wherein the lumen and the second lumen comprise an electrically insulating material configured to inhibit traversal of electrical signals through walls of the lumen and the second lumen.

26. The lead receptacle of claim 24, wherein the intercostal space of the patient is the intercostal space associated with a cardiac notch of the left lung of the patient.

27. The lead receptacle of claim 24, wherein the proximal end of the lumen is configured to terminate adjacent the pleural space of the patient.

28. The lead receptacle of claim 24, wherein the proximal end of the lumen is configured to terminate in the mediastinum of the patient.

29. The lead receptacle of claim 24, wherein the lumen is configured to be pushed into an intercostal muscle of the patient within the intercostal space.

30. The lead receptacle of claim 24, wherein the one or more cardiac leads are configured to carry electrical stimulation therapy from a pulse generator to a heart of the patient.

31. The lead receptacle of claim 24, wherein the lumen is coated with a pharmacological agent.
