Abstract

An electrical stimulation lead latching kit includes a connector having a housing that defines a lead lumen and a latching lumen that at least partially intersects the lead lumen; and a latching device including a latching pin, a handle, and an attaching element that attaches the latching pin to the handle. The latching pin has a longitudinal surface and is configured for insertion into the latching lumen, and the attaching element is configured to enable the latching pin to detach from the handle when the latching pin is in the latching lumen. When the latching pin is positioned in the latching lumen and a portion of an electrical stimulation lead or lead extension is positioned in the lead lumen, the longitudinal surface of the latching pin engages the electrical stimulation lead or lead extension to latch the electrical stimulation lead or lead extension to the connector.

Claims

1. An electrical stimulation lead latching kit, comprising:

a connector comprising a housing that defines a lead lumen and a latching lumen that at least partially intersects the lead lumen, wherein the lead lumen is configured to receive a portion of an electrical stimulation lead or lead extension; and

a latching device comprising a latching pin, a handle, and an attaching element that attaches the latching pin to the handle, wherein the latching pin has a longitudinal surface and is configured for insertion into the latching lumen and the attaching element is configured to enable the latching pin to detach from the handle when the latching pin is in the latching lumen, wherein the latching pin has a cross-sectional dimension so that, when the latching pin is positioned in the latching lumen and the portion of the electrical stimulation lead or lead extension is positioned in the lead lumen, the longitudinal surface of the latching pin engages the portion of the electrical stimulation lead or lead extension to latch the electrical stimulation lead or lead extension to the connector.

2. The electrical stimulation lead latching kit of claim 1, wherein the attaching element is a frangible portion between the latching pin and the handle.

3. The electrical stimulation lead latching kit of claim 1, wherein the housing of the connector comprises at least two lead lumens that each at least partially intersect the latching lumen.

4. The electrical stimulation lead latching kit of claim 1, wherein the latching pin is cylindrical.

5. The electrical stimulation lead latching kit of claim 1, wherein the latching pin is a modified cylinder with a rounded, longitudinal surface and one flat, longitudinal surface.

6. The electrical stimulation lead latching kit of claim 1, wherein the latching lumen has a longitudinal dimension that is at least as long as a longitudinal dimension of the latching pin.

7. The electrical stimulation lead latching kit of claim 1, wherein the latching pin has a tapered proximal end portion.

8. The electrical stimulation lead latching kit of claim 1, wherein at least one portion of the latching lumen is threaded and a portion of the latching pin is also threaded.

9. The electrical stimulation lead latching kit of claim 1, wherein an end of the latching pin comprises a recess configured to receive an end portion of a tool.

10. The electrical stimulation lead latching kit of claim 1, wherein the housing includes another lead lumen that at least partially intersects the latching lumen and is disposed opposite the lead lumen with the latching lumen between the lead lumen and the other lead lumen.

11. The electrical stimulation lead latching kit of claim 1, wherein the latching pin has the cross-sectional dimension so that, when the latching pin is positioned in the latching lumen and the portion of the electrical stimulation lead or lead extension is positioned in the lead lumen, the latching pin compresses the portion of the electrical stimulation lead or lead extension to latch the electrical stimulation lead or lead extension to the connector.

12. The electrical stimulation lead latching kit of claim 1, further comprising the electrical stimulation lead, wherein the electrical stimulation lead comprises

a lead body having a distal end portion, a proximal end portion, and a longitudinal length;

a plurality of electrodes disposed along the distal end portion of the lead body;

a plurality of terminals disposed along the proximal end portion of the lead body; and

a plurality of conductors electrically coupling the terminals to the electrodes.

13. The electrical stimulation lead latching kit of claim 1, wherein the housing of the connector includes another latching lumen that at least partially intersects the lead lumen.

14. The electrical stimulation lead latching kit of claim 1, further comprising a control module wherein the control module comprises the connector.

15. The electrical stimulation lead latching kit of claim 14, further comprising a pin disposal tool that includes a housing, the housing of the pin disposal tool including a control module lumen and a pin catching compartment that extends from the control module lumen, wherein the control module lumen is configured to receive the housing of the connector, wherein the pin catching compartment is configured to at least partially align with the latching lumen of the housing of the connector when the control module lumen receives the housing of the connector, wherein the pin catching compartment is further configured to receive the latching pin from the latching lumen of the housing of the connector when the pin catching compartment at least partially aligns with the latching lumen of the housing of the connector.

16. The electrical stimulation lead latching kit of claim 1, further comprising a lead extension, wherein the lead extension comprises the connector.

17. The electrical stimulation lead latching kit of claim 1, further comprising a lead anchor, wherein the lead anchor comprises the connector.

19. A method of latching an electrical stimulation lead or lead extension using the electrical stimulation lead latching kit of claim 1, the method comprising:

inserting a portion of the electrical stimulation lead or lead extension into the lead lumen of the housing of the connector of the electrical stimulation lead latching kit;

inserting the latching pin of the latching device into the latching lumen of the housing of the connector to engage the electrical stimulation lead or lead extension to latch the electrical stimulation lead or lead extension to the connector; and

detaching the latching pin from the handle while the latching pin is positioned in the latching lumen.

20. A method of unlatching an electrical stimulation lead or lead extension using the electrical stimulation lead latching kit of claim 15, the method comprising:

providing the control module of the electrical stimulation lead latching kit with a portion of the lead or lead extension inserted in the lead lumen and the latching pin disposed in the latching lumen and engaging the portion of the electrical stimulation lead or lead extension;

inserting the housing of the connector into the control module lumen of the pin disposal tool to at least partially align the pin catching compartment of the pin disposal tool with the latching lumen of the housing of the connector; and

pushing the latching pin from the latching lumen into the pin catching compartment of the pin disposal tool to disengage the latching pin from the portion of the electrical stimulation lead or lead extension to unlatch the electrical stimulation lead or lead extension.

18. A connector, comprising:

a housing that defines a lead lumen and a latching lumen that at least partially intersects the lead lumen, wherein the lead lumen is configured to receive a portion of an electrical stimulation lead or lead extension; and

a latching pin disposed in the latching lumen, wherein the latching pin has a longitudinal surface that is configured for rotation between an unlocked position and a locked position, wherein, in the unlocked position, the connector is configured for insertion or removal of a portion of the electrical stimulation lead or lead extension from the lead lumen and, in the locked position with the portion of the electrical stimulation lead or lead extension disposed in the lead lumen, the longitudinal surface of the latching pin engages the portion of the electrical stimulation lead or lead extension to latch the electrical stimulation lead or lead extension to the connector.
