Abstract

Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

Claims26

Dependent claims

An apparatus for non-thermal tissue ablation comprising:

a) a main body configured for handheld operation;
b) a tip comprising a skin-penetrating component comprising one or more sharpened hollow coring needles, wherein said tip is detachably attached to said main body and wherein each of said one or more sharpened hollow coring needles is configured to produce a plurality of ablated tissue portions by penetrating into and retracting from skin;
and
c) a translating mechanism disposed in the main body for driving said one or more sharpened hollow coring needles across a region of the skin in one or two directions that are orthogonal to a longitudinal movement of the hollow coring needles penetrating into the skin and retracting the hollow coring needles from the skin.
