Abstract

An operating room connector is used in conjunction with a multiple electrode SCS system which can easily detach and connect to an external trial stimulator (ETS). By connecting the electrode SCS system to a stylet handle, and then locking the stylet handle within a slot of the connector platform, a user is able to minimize the required steps in connecting the ETS to the implanted SCS lead system. The ETS can then be used to readjust the position of the electrode array(s) previously implanted to deliver an optimal stimulation therapy.

Claims

1. A method for positioning at least one lead system within a patient, the method comprising:

(a) engaging a first lead system with a first stylet wire through a central lumen of the first lead system, wherein the first stylet wire is attached to a first stylet handle, wherein the first lead system has a distal end and a proximal end, the distal end comprising a plurality of spaced-apart electrode contacts and the proximal end comprising a plurality of spaced-apart electrical terminals;

(b) maneuvering the first lead system to a first stimulation region within the patient using the first stylet wire; and

(c) locking the first stylet handle to a connector platform, wherein the connector platform includes a first open slot and a second open slot that each extend along a surface of the connector platform such that the first open slot and the second open slot are laterally spaced-apart from one another and extend parallel to one another, wherein the first stylet handle is locked to the connector platform by engaging a first front locking member of the first stylet handle onto a first front locking groove, and engaging a first rear locking member of the first stylet handle onto a first rear locking groove, both the first front locking groove and the first rear locking groove defined within the first open slot, wherein a plurality of first mating contacts are disposed within the first open slot, and wherein at least one of the plurality of first mating contacts aligns with at least one of the plurality of spaced-apart electrical terminals of the first lead system when the first stylet handle is inserted into the first open slot.

2. The method of claim 1, further comprising disconnecting the first stylet handle from the connector platform and removing the first stylet wire from the first lead system.

3. The method of claim 1, further comprising (d) connecting an external trial stimulator to at least one of the plurality of first mating contacts.

4. The method of claim 3, further comprising (e) using the first stylet wire to adjust the positioning of the distal end of the first lead system to a stimulation location within the first stimulation region.

5. The method of claim 4, further comprising (f) applying stimulation therapy to the distal end of the first lead system with the external trial stimulator.

6. The method of claim 5, wherein applying stimulation therapy to the distal end of the first lead system with the external trial stimulator comprises (g) testing the efficacy of the stimulation therapy.

7. The method of claim 6, further comprising (h) using the first stylet wire to readjust the positioning of the distal end of the first lead system to a different stimulation location within the first stimulation region and repeating (f), (g), and (h) until a desired stimulation location for the first lead system is established within the first stimulation region.

8. The method of claim 7, further comprising disconnecting the first stylet handle from the connector platform and removing the first stylet wire from the first lead system.

9. The method of claim 8, further comprising connecting the first lead system to an implantable pulse generator.

10. The method of claim 9, further comprising applying electrical current to the distal end of the first lead system with the implantable pulse generator to deliver stimulation therapy to the patient.

11. The method of claim 1, further comprising engaging a second lead system with a second stylet wire through a central lumen of the second lead system, wherein the second stylet wire is attached to a second stylet handle, and wherein the second lead system has a distal end and a proximal end, the distal end comprising a plurality of spaced-apart electrode contacts and the proximal end comprising a plurality of spaced-apart electrical terminals.

12. The method of claim 11, further comprising maneuvering the second lead system to a second stimulation region within the patient using the second stylet wire.

13. The method of claim 12, further comprising locking the second stylet handle to the second open slot of the connector platform such that the second stylet handle is inserted into the second open slot.

14. The method of claim 13, further comprising disconnecting the second stylet handle from the connector platform and removing the second stylet wire from the second lead system.

15. The method of claim 13, further comprising connecting the external trial stimulator to the connector platform.

16. The method of claim 15, further comprising using the second stylet wire to adjust the positioning of the distal end of the second lead system to a stimulation location within the second stimulation region.

17. The method of claim 16, further comprising applying stimulation therapy to the distal end of the second lead system with the external trial stimulator.

18. The method of claim 17, further comprising using the second stylet wire to repeatedly readjust the positioning of the distal end of the second lead system to a different stimulation location within the second stimulation region and applying stimulation therapy to the distal end of the second lead system with the external trial stimulator to test the efficacy of the stimulation therapy until a desired stimulation location for the second lead system is established within the second stimulation region.

19. The method of claim 1, wherein (c) locking the first stylet handle to the connector platform comprises inserting the first stylet handle into the first open slot, the first open slot extending along a flat surface of the connector platform.

20. The method of claim 1, wherein engaging the first rear locking member onto the first rear locking groove defined in the first open slot comprises snapping the first rear locking member onto the first rear locking groove.
