Abstract
A device to facilitate ablation of tissue, such as for forming one or more openings in the tissue for transdermal monitoring and/or delivery applications. The device comprises: (a) a support layer having at least one aperture therein, and (b) at least one energy absorbent film layer disposed over the at least one aperture in the support layer for making substantial contact with tissue through the aperture. The at least one energy absorbent film layer is under a tension force and absorbs energy focused thereon to thermally ablate the tissue. After ablation, the layer breaks apart allowing access to the ablated tissue beneath it.
