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.
Claims18
A device to facilitate thermal ablation of tissue, comprising:
- (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, wherein the at least one energy absorbent film layer is under a tension force;
- and absorbs energy focused thereon to thermally ablate the tissue.
A method for forming openings in a tissue comprising the steps of:
- (a) positioning a support layer having an aperture therein on a tissue;
- (b) positioning an energy absorbent film layer over the aperture to make substantial contact with the tissue through the aperture;
- and
- (c) focusing energy onto the at least one energy absorbent film layer to conduct heat to the tissue thereby ablating the tissue.
