Transdermal Medical Patch

A medical patch having a top surface, an opposite bottom surface and an outer perimeter extending between a trailing end and an opposite leading end, the patch comprising:

• a first adhesive centrally disposed inward from the outer perimeter on only a portion of the bottom surface of the medical patch;
• a second adhesive disposed only proximate its outer perimeter on the bottom surface of the medical patch without overlapping the first adhesive;
• the second adhesive exhibiting a higher peel force than that of the first adhesive;
• a central liner disposed on only a portion of the bottom surface of the patch completely covering the first adhesive, an outer perimeter of the central liner being disposed inward a predetermined distance from the outer perimeter of the patch;
• a leading end outer perimeter liner covering only a leading portion of the bottom surface of the medical patch proximate the leading end and extending to the outer perimeter of the medical patch;
• and
• a trailing end outer perimeter liner covering only a trailing portion of the bottom surface of the medical patch disposed proximate the trailing end and extending to the outer perimeter of the medical patch;
• wherein each of the outer perimeter liners are laterally folded over onto itself with its outer contour substantially aligned;
• the outer perimeter liners are arranged so that respective folds of each of the outer perimeters abut one another along a fold line interface thereby defining an opening that exposes the first adhesive;
• wherein the central liner overlaps only a portion of each of the outer perimeter liners;
• the outer perimeter liners together with the central liner completely cover the bottom surface of the medical patch.

A self-positioning neurostimulation medical patch for stimulation of a sacral (S3 foramen) spinal nerve;

• the medical patch having a top surface, a bottom surface, an outer perimeter, a leading end and an opposite trailing end, the leading and trailing ends defining a central longitudinal axis;
• the medical patch comprising:
• an electrode for generating an electrical signal, the electrode being disposed proximate the leading end of the medical patch;
• a liner covering the bottom surface of the medical patch;
• wherein the outer perimeter of the medical patch has a linear section disposed symmetrically on both sides of the central longitudinal axis;
• the linear sections are oriented at an angle of approximately ±60 degrees relative to the central longitudinal axis;
• the electrode is disposed at an intersection of parallel lines approximately 2 cm inward relative to the respective linear sections.
