Disposable radio frequency needle cartridges having absorbing containment barriers
First Claim
1. A needle cartridge for use with a transdermal microneedling apparatus, the needle cartridge comprising:
- a base portion having a proximal end and a distal end opposite its proximal end;
a housing having a proximal end coupled to the distal end of the base portion, and having an open distal end opposite its proximal end; and
a radio frequency (RF) capsule configured to be received within the housing, and comprising a proximal end having a drive shaft mount configured to receive an end of a drive shaft, and a distal end opposite its proximal end, the RF capsule further comprising;
a power source,RF oscillator circuitry powered by the power source and configured to generate RF energy,a needle unit disposed at the distal end of the RF capsule and comprising at least one needle extending therefrom, andtransfer circuitry configured to transfer the generated RF energy from the RF oscillator circuitry to the at least one needle.

Abstract
Disclosed herein are unique needle cartridges for use with transdermal microneedling devices that generate and emit low energy RF signals to, and prevent backflow of liquid(s) from, the skin of a patient. One embodiment may comprise a base portion and a sleeve coupled to the base portion. Such an embodiment may also comprise an RF needle capsule disposed within the housing, and having a needle unit comprising at least one needle on an end thereof. Also, the needle cartridge comprises a drive shaft disposed through the base portion and coupled to the needle unit, and configured to be driven reciprocally along a longitudinal axis of the base portion and thereby move the RF needle capsule reciprocally such that the needles of the needle unit extend beyond and retract within the housing. Such RF needle cartridges further include an absorbing barrier disposed within the housing to prevent the backflow of liquid(s) from the needle unit by absorbing such liquid(s).
