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 connector for connecting at least one lead system to an external trial stimulator, the connector comprising:

a connector platform having an outer surface;

a first open slot defined along the outer surface of the connector platform, the first open slot having a front portion, an opposing rear portion, and a longitudinal length, the first open slot comprising

a first front locking groove disposed in the front portion of the first open slot,

a first rear locking groove disposed in the rear portion of the first open slot, and

a plurality of spaced-apart first mating contacts disposed along the longitudinal length of the first open slot; and

a first stylet handle configured and arranged for removably locking to the first open slot of the connector platform, the first stylet handle having a front portion, an opposing rear portion, and a longitudinal length, the first stylet handle comprising

a first stylet wire permanently attached to the first stylet handle, the first stylet wire configured and arranged to engage the at least one lead system,

a first front locking member disposed along the front portion of the first stylet handle, the first front locking member configured and arranged to removably engage the first front locking groove, and

a first rear locking member disposed along the rear portion of the first stylet handle, the first rear locking member configured and arranged to removably engage the first rear locking groove.

2. The connector of claim 1, wherein the connector platform further comprises

a second open slot defined along the outer surface, the second open slot having a front portion, an opposing rear portion, and a longitudinal length, the second open slot comprising

a second front locking groove disposed in the front portion of the second open slot,

a second rear locking groove disposed in the rear portion of the second open slot, and

a plurality of spaced-apart second mating contacts disposed along the longitudinal length of the second open slot;

and

a second stylet handle configured and arranged for removably locking to the connector platform, the second stylet handle having a front portion, an opposing rear portion, and a longitudinal length, the second stylet handle comprising

a second stylet wire permanently attached to the second stylet handle, the second stylet wire configured and arranged to engage the at least one lead system,

a second front locking member disposed along the front portion of the second stylet handle, the second front locking member configured and arranged to removably engage the second front locking groove, and

a second rear locking member disposed along the rear portion of the second stylet handle, the second rear locking member configured and arranged to removably engage the second rear locking groove.

3. The connector of claim 2, wherein the at least one lead system comprises a first lead with a proximal end and an opposing distal end, wherein a plurality of spaced-apart electrode contacts are disposed along the distal end and a plurality of spaced-apart electrical terminals are disposed along the proximal end.

4. The connector of claim 3, wherein the first stylet wire is configured and arranged to engage the first lead.

5. The connector of claim 3, wherein at least one of the plurality of first mating contacts of the connector platform is configured and arranged to align with at least one of the plurality of spaced-apart electrical terminals of the first lead when the first stylet handle is removably locked to the first open slot.

6. The connector of claim 3, wherein the at least one lead system further comprises a second lead with a proximal end and an opposing distal end, wherein a plurality of spaced-apart electrode contacts are disposed along the distal end and a plurality of spaced-apart electrical terminals are disposed along the proximal end.

7. The connector of claim 6, wherein the second stylet wire is configured and arranged to engage the second lead.

8. The connector of claim 6, wherein at least one of the plurality of second mating contacts of the connector platform is configured and arranged to align with at least one of the plurality of spaced-apart electrical terminals of the second lead when the second stylet handle is removably locked to the second open slot.

9. The connector of claim 2, wherein the first open slot and the second open slot are laterally spaced-apart from one another.

10. The connector of claim 2, wherein the first open slot and the second open slot extend parallel to one another.

11. The connector of claim 1, wherein the first stylet handle is configured and arranged to removable couple to the connector platform when at least one of the first front locking member removably engages the first front locking groove or the first rear locking member removably engages the first rear locking groove.

12. The connector of claim 1, wherein the first stylet handle is configured and arranged to removable couple to the connector platform when both the first front locking member removably engages the first front locking groove and the first rear locking member removably engages the first rear locking groove.

13. The connector of claim 1, wherein the connector platform has a top surface, a bottom surface opposite to the top surface, a front surface, a rear surface opposite to the front surface, a first side surface, and a second side surface opposite to the first side surface.

14. The connector of claim 13, wherein the first open slot is defined along the top surface of the connector platform.

15. The connector of claim 1, wherein the first stylet handle is configured and arranged for removably locking to the first open slot of the connector platform by clipping down onto the first open slot.

16. The connector of claim 1, wherein the first rear locking member is configured and arranged to removably engage the first rear locking groove by snapping the first rear locking member into the first rear locking groove.

17. The connector of claim 1, further comprising an adhesive permanently attaching the first stylet wire to the first stylet handle.

18. The connector of claim 1, wherein the connector platform defines an opening along the outer surface of the connector platform, the opening configured and arranged to receive an operating room external cable.

19. The connector of claim 1, further comprising an operating room external cable permanently coupled to the connector platform.

20. The connector of claim 1, wherein the first stylet handle is formed from plastic.
