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 method of insulating intercostal muscle from a cardiac lead comprising:

inserting a lead receptacle into an intercostal space of a patient, the lead receptacle comprising a lumen configured to traverse from an outermost surface of an outermost intercostal muscle to the innermost surface of the innermost intercostal muscle of the patient, the lead receptacle configured to prevent movement of the lead receptacle toward the innermost intercostal muscle and toward the outermost intercostal muscle and to support a lead traversing through the lumen;

fixing the lead receptacle in place in the intercostal space of the patient

feeding a distal end of the cardiac lead through the lead receptacle; and

positioning the distal end of the cardiac lead within a mediastinum of the patient to deliver electrical stimulation therapy to a heart of the patient.

2. The method as in claim 1, wherein the lumen is made from an electrically insulating material.

3. The method as in claim 1, wherein the lumen is coated with a pharmacological agent.

4. The method of claim 1, wherein fixing the lead receptacle in place comprises using a hook.

5. The method of claim 1, wherein fixing the lead receptacle in place comprises using a spring.

6. The method of claim 1, wherein fixing the lead receptacle in place comprises using a screw.

7. The method of claim 1, wherein fixing the lead receptacle in place comprises using a tine.

8. The method of claim 1, wherein fixing the lead receptacle in place comprises fixing the lead receptacle into soft tissues within a thoracic cavity.

9. The method of claim 1, wherein inserting the lead receptacle further comprises inserting the lead receptacle to abut the superficial facia on an outermost side of a cardiac notch.

10. The method of claim 1, wherein inserting the lead receptacle further comprises inserting the lead receptacle to abut an endothoracic facia or a parietal pleura on an innermost side of a cardiac notch.

11. The method of claim 1, wherein inserting the lead receptacle further comprises inserting the lead receptacle through an incision at off-set positions of a plurality of layers of intercostal muscle, the inserting resulting in a transverse pressure applied by the plurality of layers of intercostal muscle against the lead receptacle.

12. The method of claim 1, wherein inserting the lead receptacle further comprises inserting the cardiac lead within the mediastinum of the patient adjacent, but not touching, the heart.

13. The method of claim 1, the method further comprising detecting a state of an organ of the patient by a sensor on the distal end of the cardiac lead.
