Abstract

A medical patch having a multi-piece bottom liner including a central liner sequentially removable independently of two outer perimeter liners. The multi-piece liner covering two adhesives of different peel force. Removal of the central liner exposes a first temporary/repositionable adhesive. Once properly positioned, the outer perimeter liners are removed to expose a second stronger adhesive. A foam cushioning layer is disposed beneath and extends beyond a footprint of every printed circuit board to prevent skin irritation. The medical patch may be designed specifically for stimulation of the sacral (S3 foramen) spinal nerve without the use of a separate mechanical placement tool or assistance by another.
