1. A handheld roller assembly for treating a patient'"'"'s dermal surface, the assembly comprising:
- a handle having a longitudinal axis, a proximal end and a distal end;
an axle disposed toward the distal end of the handle, the axle extending substantially transverse to the longitudinal axis of the handle;
a roller cartridge having an outer surface and lumen configured to slideably receive the axle, the lumen extending longitudinally along a central axis of the roller cartridge;
a quick-release mechanism configured to secure the roller cartridge to the axle and release the roller cartridge from the axle; and
a plurality of microstructures extending normal to the outer surface of the roller cartridge.

Abstract
A microstructure roller apparatus including a handle, an axle, a retention mechanism and a roller cartridge is disclosed herein. The handle can have an axle at one end and a grip portion at the other end. A generally cylindrical roller cartridge can be coupled to the axle by inserting the axle into a central lumen of the roller cartridge. A retention mechanism on the axle can hold the roller cartridge to the axle. The cartridge can include multiple strips that have an array of microstructures along the length and width of each strip. The handle can be weighted to provide a correct amount of pressure to the patient.

17. A roller assembly for treating a patient'"'"'s dermal surface, the assembly comprising:
-
a handle, the handle comprising a projecting portion that projected from the handle in a direction transverse to a longitudinal axis of the handle; a roller cartridge configured to slide over the projecting portion of the handle; a coupling member configured to automatically lock the roller cartridge to the handle without preventing rotation of the roller cartridge with respect to the handle, and further configured to release the roller cartridge from the handle when activated by a user; and a plurality of microstructures extending normal to an outer surface of the roller cartridge.
