Abstract

A lead includes a lead body extending from a distal end to a proximal end, and at least one conductor disposed within the lead body and extending from the distal end to the proximal end of the lead body. The lead further includes an outer terminal ring, a terminal pin, and an insulative sleeve disposed between the outer terminal ring and the terminal pin, where the insulative sleeve is coupled with the outer terminal ring with a snap-fit connection. A pin latch is disposed on an outer periphery surface of the insulative sleeve, where the pin latch is rotatable about a hinge point.

Claims

1. A lead, comprising:

a lead body;

a first conductive member disposed along the lead body, the first conductive member having a bore therethrough;

an insulative sleeve coupled with the first conductive member, the insulative sleeve having a coupled position and an uncoupled position, the insulative sleeve including at least one deflecting member disposed along the insulative sleeve, the deflecting member having a deflected position when the insulative sleeve is in the coupled position; and

a second conductive member coupled with the insulative sleeve;

wherein the at least one deflecting member is radially disposed between an inner surface of the second conductive member and an outer surface of the first conductive member.

2. The lead of claim 1, wherein the first conductive member is a terminal pin.

3. The lead of claim 1, wherein the second conductive member is a terminal ring.

4. The lead of claim 1, further comprising means for resisting rotation of the insulative sleeve relative to at least one of the first conductive member or the second conductive member.

5. The lead of claim 4, wherein the means for resisting rotation includes at least one axial groove of the second conductive member.

6. The lead of claim 5, wherein the at least one axial groove includes a plurality of V-shaped grooves disposed along an inner surface of the second conductor member.

7. The lead of claim 1, wherein an inner surface of the insulative sleeve is tapered from a first sleeve portion to a second sleeve portion.

8. The lead of claim 1, wherein the insulative sleeve has an outer surface and the deflecting member is disposed along the outer surface of the insulative sleeve.

9. The lead of claim 1, wherein the at least one deflecting member is compressed to a deflected position by the inner surface of the second conductive member and the outer surface of the first conductive member.

10. The lead of claim 1, wherein the insulation sleeve is longer than the second conductive member.

11. A lead, comprising:

a lead body;

a first conductive member disposed along the lead body, the first conductive member having a bore therethrough;

an insulative sleeve coupled with the first conductive member, the insulative sleeve having a coupled position and an uncoupled position, the insulative sleeve including at least one deflecting member disposed along the insulative sleeve, the deflecting member having a deflected position when the insulative sleeve is in the coupled position; and

a second conductive member coupled with the insulative sleeve, the second conductive member including a coupling portion adapted to engage the insulative sleeve;

wherein the at least one deflecting member is radially disposed between an inner surface of the second conductive member and an outer surface of the first conductive member.

12. The lead of claim 11, wherein the first conductive member is a terminal pin.

13. The lead of claim 11, wherein the second conductive member is a terminal ring.

14. The lead of claim 11, further comprising means for resisting rotation of the insulative sleeve relative to at least one of the first conductive member or the second conductive member.

15. The lead of claim 14, wherein the means for resisting rotation includes at least one axial groove of the second conductive member.

16. The lead of claim 11, wherein an inner surface of the insulative sleeve is tapered from a first sleeve portion to a second sleeve portion.

17. The lead of claim 11, wherein the insulative sleeve has an outer surface and the deflecting member is disposed along the outer surface of the insulative sleeve.

18. The lead of claim 11, wherein the at least one deflecting member is compressed to a deflected position by the inner surface of the second conductive member and the outer surface of the first conductive member.

19. The lead of claim 11, wherein the insulation sleeve is longer than the second conductive member.

20. The lead of claim 11, wherein the coupling portion includes an annular recess configured to engage each deflecting member.

21. A lead, comprising:

a lead body;

a first conductive member disposed along the lead body, the first conductive member having a bore therethrough;

an insulative sleeve coupled with the first conductive member, the insulative sleeve having a coupled position and an uncoupled position, the insulative sleeve including at least one deflecting member disposed along the insulative sleeve, the deflecting member having a deflected position when the insulative sleeve is in the coupled position;

a second conductive member coupled with the insulative sleeve; and

a plurality of axial grooves disposed along an inner surface of the second conductor member in order to resist rotation of the insulative sleeve relative to at least one of the first conductive member or the second conductive member.
