Abstract

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an implantable medical device. The implantable medical device may include an implantable pacing member having a housing and a lead input. A lead may be coupled to the lead input. The lead may be designed to extend along a pericardial space, epicardium, or both and engage a heart chamber. A passageway may be defined along a portion of the length of the lead.

Claims (30)

1. A method of implanting an implantable medical device within a patient, comprising:

implanting a lead interior of the patient's rib cage by advancing the lead along a sub-xiphoid pathway, the lead including at least one electrode; and

subcutaneously implanting a pacing member exterior of the patient's rib cage, the pacing member including a housing, a pulse generator within the housing, and a power source within the housing;

wherein a proximal end of the lead is connected to the pacing member exterior of the patient's rib cage and a distal end of the lead is located interior of the patient's rib cage, the distal end of the lead including a distalmost tip;

wherein the at least one electrode remains exterior of all chambers of the patient's heart subsequent to the completion of implanting the lead interior of the patient's rib cage;

wherein at least a portion of the pacing member extends superior of the distalmost tip of the lead subsequent to the completion of implanting the lead interior of the patient's rib cage and subcutaneously implanting the pacing member exterior of the patient's rib cage.

2. The method of claim 1 , wherein the at least one electrode comprises at least two electrodes including bipolar electrodes.

3. The method of claim 1 , wherein the lead is positioned in contact with an epicardium of the patient's heart.

4. The method of claim 1 , wherein the at least one electrode is positioned in contact with an epicardium of the patient's heart.

5. The method of claim 1 , wherein the lead is positioned in a pericardial space of the patient.

6. The method of claim 1 , wherein the implantable medical device, including the housing of the pacing member and the lead connected thereto, is implanted interior of the patient's skin.

7. The method of claim 1 , wherein the lead includes a pre-formed bend.

8. The method of claim 1 , wherein the lead is advanced through a delivery catheter.

9. The method of claim 1 , wherein the proximal end of the lead is detachably connected to a lead input of the pacing member.

10. The method of claim 1 , further comprising anchoring the distal end of the lead to an epicardium of the patient's heart.

11. A method of implanting an implantable medical device within a patient, comprising:

implanting a lead interior of the patient's rib cage by advancing the lead along a guidewire, the lead including at least one electrode; and

subcutaneously implanting a pacing member exterior of the patient's rib cage, the pacing member including a housing, a pulse generator within the housing, and a power source within the housing;

wherein a proximal end of the lead is connected to a lead input of the pacing member exterior of the patient's rib cage and a distal end of the lead is located interior of the patient's rib cage, the distal end of the lead including a distalmost tip;

wherein the at least one electrode remains exterior of all chambers of the patient's heart subsequent to the completion of implanting the lead interior of the patient's rib cage;

wherein at least a portion of the pacing member extends superior of the distalmost tip of the lead subsequent to the completion of implanting the lead interior of the patient's rib cage and subcutaneously implanting the pacing member exterior of the patient's rib cage.

12. The method of claim 11 , wherein the at least one electrode comprises at least two electrodes including bipolar electrodes.

13. The method of claim 11 , wherein the lead is positioned in contact with an epicardium of the patient's heart.

14. The method of claim 11 , wherein the at least one electrode is positioned in contact with an epicardium of the patient's heart.

15. The method of claim 11 , wherein the lead is positioned in a pericardial space of the patient.

16. The method of claim 11 , wherein the implantable medical device, including the housing of the pacing member and the lead connected thereto, is implanted interior of the patient's skin.

17. The method of claim 11 , wherein the lead includes a pre-formed bend.

18. The method of claim 11 , wherein the lead is advanced through a delivery catheter.

19. The method of claim 11 , wherein the proximal end of the lead is detachably connected to a lead input of the pacing member.

20. The method of claim 11 , further comprising anchoring the distal end of the lead to an epicardium of the patient's heart.
