1. A placement structure comprising: two sets of wings for facilitating placement of an implantable device; said implantable device having an outer surface and having at least two electrodes, a first electrode and a second electrode configured to be implanted proximate to neural/muscular tissue; a holder comprised of elastic material that is configured to retain said implantable device and having a hollow longitudinal cavity; said hollow longitudinal cavity configured to accept said implantable device across its length and perpendicular to the longitudinal axis of the longitudinal cavity; said hollow longitudinal cavity having a proximal portion and a distal portion configured for holding and retaining said implantable device; said hollow longitudinal cavity configured to retain said implantable device and said first electrode and said second electrode in direct contact with the neural/muscular tissue; said implantable device snapped into said hollow longitudinal cavity where it is elastically retained by said elastic material of said holder; at least two sets of elastic wings comprising a first set and a second set of elastic wings configured to capture neural/muscular tissue; and said placement structure comprised of biocompatible plastic.
