Implantable medical devices and methods for making and delivering implantable medical devices
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.
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 an arcuate path, 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.
2. The method of claim 1 , wherein the lead is detachably connected with the pacing member at the lead input.
3. The method of claim 1 , wherein the at least one electrode comprises at least two electrodes including bipolar electrodes.
4. The method of claim 1 , wherein the lead 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 lead includes a guidewire lumen extending therein.
7. The method of claim 6 , wherein the step of implanting the lead includes advancing the lead along a guidewire disposed in the guidewire lumen.
8. The method of claim 1 , further comprising anchoring a distal end of the lead within the patient.
9. A method of implanting an implantable medical device within a patient, comprising:
implanting a lead between the patient's rib cage and the patient's heart by advancing the lead along an arcuate path, 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, a power source within the housing, and a lead input;
wherein a proximal end of the lead is detachably connected to the 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.
10. The method of claim 9 , wherein the step of implanting the lead includes advancing the lead along an arcuate path.
11. The method of claim 9 , wherein the at least one electrode comprises at least two electrodes including bipolar electrodes.
12. The method of claim 9 , further comprising:
positioning the lead in contact with an epicardium of the patient's heart.
13. The method of claim 9 , further comprising:
positioning the lead in a pericardial space of the patient.
14. The method of claim 9 , further comprising:
anchoring a distal end of the lead within the patient.
15. The method of claim 9 , wherein the lead includes a guidewire lumen extending therein.
16. The method of claim 15 , wherein the step of implanting the lead includes advancing the lead along a guidewire disposed in the guidewire lumen.
17. The method of claim 9 , wherein the lead includes a pre-formed bend.
18. A method of implanting an implantable medical device within a patient, comprising:
implanting a distal end of a lead interior of the patient's rib cage, 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;
wherein the lead includes a pre-formed bend.
19. The method of claim 18 , wherein the at least one electrode comprises at least two electrodes including bipolar electrodes.
20. The method of claim 18 , wherein the proximal end of the lead is detachably connected to a lead input of the pacing member.
