Abstract

One embodiment is an electrical stimulation arrangement that includes a lead having a lead body and first contacts disposed along a first end surface of the proximal end portion of the lead body; and a lead extension having a lead extension body and second contacts disposed along the second end surface of the distal end portion of the lead extension body. Several of the first and second contacts form contact pairs with each contact pair containing one first contact and one second contact. For each contact pair, either the first contact or second contact is a male pin and the other of the first contact or second contact is a female socket configured and arranged to mate with the male pin when the proximal end portion of the lead body is mated to the distal end portion of the lead extension body forming a connector.

wherein a plurality of the first and second contacts form contact pairs, each contact pair containing one of the first contacts and one of the second contacts, wherein, for each contact pair, either the first contact or second contact of the contact pair is a male pin and another of the first contact or second contact of the contact pair is a female socket configured and arranged to mate with the male pin when the proximal end portion of the lead body is mated to the distal end portion of the lead extension body forming a connector.

2. The electrical stimulation arrangement of claim 1, wherein the first contact of each contact pair is the male pin and the second contact of each contact pair is the female receptacle.

3. The electrical stimulation arrangement of claim 1, wherein the first contacts are arranged in a first linear array and the second contacts are arranged in a second linear array.

4. The electrical stimulation arrangement of claim 1, wherein the first contacts are arranged in a first two-dimensional array and the second contacts are arranged in a second two-dimensional array.

5. The electrical stimulation arrangement of claim 1, further comprising a gasket disposed on each male pin or within each female socket.

6. The electrical stimulation arrangement of claim 1, wherein the male pins and female sockets are configured and arranged to generate a tactile or audible response when mated.

7. The electrical stimulation arrangement of claim 1, further comprising a sheath configured and arranged to slide over the connector formed by mating the proximal end portion of the lead body with the distal end portion of the lead extension body.

8. The electrical stimulation arrangement of claim 7, wherein the sheath is an elastomeric sheath.

9. The electrical stimulation arrangement of claim 7, wherein at least one of the lead body or the lead extension body comprises a flange or groove to facilitate retention of the sleeve.

10. The electrical stimulation arrangement of claim 9, wherein the sleeve comprises a flange or groove to facilitate retention of the sleeve on the lead body or the lead extension body.

11. The electrical stimulation arrangement of claim 1, wherein the proximal end portion of the lead body and the distal end portion of the lead extension body, when mated to form the connector, have a same diameter as the lead body.
