The tissue integration layer has a porous structure adapted for ingress of tissue to anchor the device when implanted. The crowning element is 5 adapted for epidermal attachment when the device is implanted and is configured such that once implanted, part of the crowning element extends through the epidermis and is accessible from outside the subject's body. The porous structure of the tissue integration layer is interconnected for tissue ingress during implantation.1/8 220 122 100 1222 12 230 240 Figure 110 120 126/ 122 124 Figure 1 A
