Abstract
This disclosure relates to an in vivo treatment of a skin lesion of a mammal comprising application of electrical energy to the skin lesion in a form of electrical pulses. At least one electrical pulse is applied. The pulse duration may be at least 1 nanosecond at the full-width-half-maximum. Surface of a tissue surrounding the skin lesion may be marked to guide the device to deliver the electric pulses at substantially precise locations on the lesion surface. This treatment may prevent at least growth of the lesion.
Claims21
A decal comprising:
- a film that is transferable to a surface of an object that is visibly different than other regions of the object surface and that has a size;
- a decal positioning mark that is usable to position the decal on the object surface;
- a device guiding mark on the film that is transferable to the object surface together with the film and that is usable to position a device in relation to the object surface after the film is transferred to the object surface;
- a marked area on the decal that:
- after the film is transferred on the surface, is usable to indicate a boundary around the visibly different region on the object surface, and
- does not comprise the film;
- wherein the decal has a front surface and a back surface;
- wherein the film has a front surface and a back surface;
- wherein the front surface of the film is configured to be in contact with the object surface after the film is transferred to the object surface;
- and
- wherein the film and the device guiding mark are configured to detachably attach to the object surface after the film is transferred to the object surface.
A method of delivering one or more electrical nanopulses to a lesion on a surface of a skin comprising:
- providing a system comprising a pulse delivery device,
- providing a decal,
- positioning the pulse delivery device using the decal, and
- delivering at least one electrical pulse to the lesion using the pulse delivery device.
