An implantable cuff electrode for collision block of pudendal nerve motor activity

An implantable cuff electrode technique for collision block of pudendal nerve motor activity has been developed and tested through acute and chronic animal studies. The necessary quasitrapezoidal stimulus parameters for acute and chronic collision block generation have been characterized and are discussed. An asymmetric two-electrode cuff design effectively produces the trains of antidromically propagated action potentials needed to implement a collision block of motor signals to the external periurethral sphincter.<>
