First Claim
1. A transdermal microneedling apparatus, comprising:
- a main body having a front end and a back end opposite its front end, the main body comprising a drive motor, drive circuitry for controlling the drive motor, and a drive linkage located on a distal end of the drive motor;
a power source capsule having a proximal end coupled to the back end of the main body, the power source capsule comprising a power source and associated power source management circuitry;
a needle cartridge having a proximal end coupled to the front end of the main body, the needle cartridge comprising;
a drive shaft disposed therethrough;
a needle unit coupled to a distal end of the drive shaft to move therewith, the needle unit having at least one needle extending therefrom;
wherein the drive shaft comprises a linkage member configured to engage the drive linkage of the drive motor; and
wherein the drive shaft is configured to be driven by the drive motor and thereby drive movement of the needle unit such that the at least one needle extends beyond and retracts within the distal end of the needle cartridge;
RF energy circuitry powered by the power source and configured to generate RF energy; and
transfer circuitry configured to transfer the generated RF energy from the RF energy circuitry to the at least one needle.

Abstract
Disclosed herein are transdermal microneedling devices that generate and emit low RF energy. Such a microneedling device may comprise a drive motor, drive circuitry for controlling the drive motor, and a drive linkage located on the drive motor rotor. The microneedling device may also comprise a power source capsule comprising a battery and associated power management circuitry. Also included may be a needle cartridge coupled to the main body, and comprising a drive shaft and a needle unit coupled to a distal end of the drive shaft to move therewith, where the needle unit has at least one needle extending therefrom. The drive shaft may comprise a linkage member configured to engage the drive linkage of the drive motor, and be configured to be driven by the drive motor and thereby drive movement of the needle unit such that the at least one needle extends beyond and retracts within the distal end of the needle cartridge. The microneedling device may also include RF energy circuitry powered by the power source and configured to generate RF energy, as well as transfer circuitry configured to transfer the generated RF energy from the RF energy circuitry to the at least one needle.
