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
A method for non-thermal tissue ablation comprising:
- a) providing a handheld device having a main body and a tip, wherein said tip comprises one or more sharpened hollow coring needles, the tip being detachably attached to the main body;
- b) penetrating into and retracting the one or more sharpened hollow coring needles into a skin to produce a plurality of ablated tissue portions;
- and
- c) 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 one or more sharpened hollow coring needles penetrating into the skin and retracting the one or more sharpened hollow coring needles from the skin, using a translating mechanism disposed in the main body.
