| abstract |
The present methods and systems provide treatment of a preselected body surface by injuring a portion of the body surface, optionally applying a composition such as a pharmaceutical agent to the injured portion of the body surface, and selection of a further portion on the body surface for the same or different injury and optional contacting with the same or different composition, wherein the further portion has a preselected geometry with respect to the first injured portion. The repetition of the selection, injury, and optional exposure to a composition with respect to successive portions of the body surface, optionally under partial or total computer control, provides efficient treatment of the body surface pursuant to the objective of regeneration, remodeling, resurfacing, restoration, follicular neogenesis, neocollagenesis, stem cell recruitment, activation, or differentiation, reepitheliazation, wound healing, or any other desired biological or physical modification. |
