Cable termination with an angularly offset parabolic wall profile

An anchor having an internal passage defined by a revolved wall profile. The anchor is conceptually divided into four regions: a neck region, a transition region, a mid region, and a distal region. Each of these regions has its own design considerations. A portion of a parabola is used to define at least part of the revolved wall profile. The parabolic portion is preferably used in at least the neck and mid regions. In order to create a tangency condition proximate the neck anchor boundary, the parabola used to create the wall profile is angularly offset from the wall profile's axis of rotation.
