A system for delivering energy to an isolated part of a mammalian body includes an electrically powered patch and a self-supporting adhesive film. The patch has a major surface and comprises a matrix of at least one flexible, biocompatible material which is capable of conforming to the isolated body part. The self-supporting adhesive film has a first non-tacky surface arranged and configured for releasable attachment to the patch and a second tacky surface, opposite the first surface, for adhesive attachment to the isolated body part. The releasable attachment between the self-supporting adhesive film and the electrically powered patch has a lower strength than the adhesive attachment between the film and the isolated body part. Thus, during use the electrically powered patch is removable from the self-supporting adhesive film while leaving the self-supporting adhesive film adhered to the isolated body part.
