Abstract

In various examples, an apparatus includes a neurostimulation interconnection apparatus including an elongate lead body including a lead proximal end and a lead distal end. The lead proximal end includes a first connector portion. A stimulation device includes a header. The header includes a second connector portion including a shape complementary to a shape of the first connector portion. The first connector portion is mateably engageable with the second connector portion, wherein one of the first connector portion and the second connector portion includes a plurality of pins and the other of the first connector portion and the second connector portion includes a plurality of sockets. There are an equal number of sockets and pins, wherein, with the first connector portion mateably engaged with the second connector portion, the pins align and electrically couple with the sockets.

Claims
