Multiple function lead assembly
First Claim
1. Apparatus for connecting a body implantable tissue stimulator and lead assembly, comprisingat least two distal electrodes on said lead assembly for electrical stimulation or sensing,at least two coaxial proximal connectors on said lead assembly axially spaced apart and electrically connected to said distal electrodes for connecting said distal electrodes with said tissue stimulation means,a female connector assembly on said body implantable tissue stimulator adapted to electrically connect said proximal connector to said stimulator,insulator means intermediate adjacent ones of said coaxial proximal connectors having fluid sealing ribs cooperating with said female connector assembly for maintaining fluid isolation between said connectors.

Abstract
Apparatus and methods are provided for manually altering the function of the distal electrodes of a body implantable tissue stimulator assembly. In one exemplary embodiment, the polarity of distal electrodes may be reversed by axially repositioning the proximal connectors within the female connector assembly of a tissue stimulator.
