A focal tissue stimulator is provided that includes a pair of concentric conductors. The conductors may include an inner conductor, and an outer conductor that has an elliptical annular shape and surrounds the inner conductor. The outer conductor may have a minor axis and a mutually-perpendicular, major axis, with a first portion of the outer conductor proximate the minor axis being closer in proximity to the inner conductor than a second portion of the outer conductor proximate the major axis. In this regard, the inner and outer conductors may be coupled or couplable to respective leads configured to deliver current for passage therebetween, with the elliptical annular shape of the outer conductor creating a pathway of increased current density at the first portion relative to the second portion. |

1. A focal tissue stimulator comprising a pair of concentric conductors, the pair of concentric conductors comprising:
an inner conductor; and an outer conductor having an elliptical annular shape and surrounding the inner conductor, the outer conductor having a minor axis and a mutually-perpendicular, major axis, a first portion of the outer conductor proximate the minor axis being closer in proximity to the inner conductor than a second portion of the outer conductor proximate the major axis, wherein the inner and outer conductors are coupled or couplable to respective leads configured to deliver current for passage therebetween, the elliptical annular shape of the outer conductor creating a pathway of increased current density at the first portion relative to the second portion. |
