Abstract

An implantable medical lead includes an adaptor coupled to a body of the lead. The adaptor holds a sensor capsule between a first portion and a second portion of the lead body.

Claims

1. A medical electrical lead, comprising:

a lead body;

a sensor capsule;

an adaptor coupled to the lead body and holding the sensor capsule in the lead body, the adaptor comprising;

an open-sided channel;

a first conductor extending within the lead body and the open-sided channel of the adaptor.

2. The lead of claim 1, wherein the first conductor comprises an electrically conductive coiled wire.

3. The lead of claim 2, wherein the coiled wire includes a lumen sized to accommodate a lead delivery wire.

4. The lead of claim 1, wherein the first conductor comprises a cabled bundle of electrically conductive wires.

5. The lead of claim 1, wherein the first conductor comprises an electrically conductive wire and further comprising a low voltage electrode coupled to the conductor along the lead body.

6. The lead of claim 1, wherein the first conductor comprises an electrically conductive wire and further comprising a high voltage electrode coupled to the conductor along the lead body.

7. The lead of claim 1, wherein the first conductor comprises a fluid infusion tube.

8. A medical electrical lead comprising:

a lead body including a first portion and a second portion, the first portion including a first lumen and a second lumen extending lengthwise therein and the second portion including a first lumen and a second lumen extending lengthwise therein;

a sensor capsule including a length; and

an adaptor coupled to the lead body and holding the sensor capsule in between the lead body portions, the adaptor comprising;

a first part including a proximal end and a proximal lumen,

a second part including a distal end and a distal lumen;

a first open-sided channel extending alongside the sensor capsule.

9. The lead of claim 8, further comprising a first conductor extending within the lead body and the open-sided channel of the adaptor.

10. The lead of claim 9, wherein the first conductor comprises an electrically conductive coiled wire.

11. The lead of claim 10, wherein the coiled wire includes a lumen sized to accommodate a lead delivery wire.

12. The lead of claim 9, wherein the first conductor comprises a cabled bundle of electrically conductive wires.

13. The lead of claim 9, wherein the first conductor comprises an electrically conductive wire and further comprising a low voltage electrode coupled to the conductor along the second portion of the lead body.

14. The lead of claim 9, wherein the first conductor comprises an electrically conductive wire and further comprising a high voltage electrode coupled to the conductor along the second portion of the lead body.

15. The lead of claim 9, wherein the first conductor comprises a fluid infusion tube.

16. A method for assembling a medical electrical lead that includes a lead body first portion, a lead body second portion and a sensor capsule positioned in between the lead body first portion and the lead body second portion, the method comprising the steps of:

coupling a sensor bus to the sensor capsule;

coupling an adaptor to the lead body first portion, the adaptor adapted to hold the sensor capsule;

placing the sensor bus, which extends from the sensor capsule coupling, within a sensor conductor lumen of the lead body first portion through a proximal end of the adaptor; and

placing a first portion of a first elongate conductor within a first open-sided channel of the adaptor.

17. The method of claim 16, wherein the first conductor comprises an electrically conductive coiled wire.

18. The method of claim 17, wherein the coiled wire includes a lumen sized to accommodate a lead delivery wire.

19. The method of claim 16, wherein the first conductor comprises a cabled bundle of electrically conductive wires.

20. The method of claim 16, wherein the first conductor comprises an electrically conductive wire and further comprising coupling a low voltage to the conductor along the second portion of the lead body.

21. The method of claim 16, wherein the first conductor comprises an electrically conductive wire and further comprising coupling a high voltage to the conductor along the second portion of the lead body.

22. The method of claim 16, wherein the first conductor comprises a fluid infusion tube.
