Abstract

The present invention provides apparatus and method for removal of body hair using electroporation. The apparatus has a pulse generator capable of generator electrical pulses of the desired amplitude and duration to kill hair follicles and an applicator having a first electrode placed in contact with a hair follicle and a second electrode interacting with the first electrode to provide an electroporating field in the tissue volume surrounding a hair to be removed. The apparatus may include a TENS system to provide patient relief from discomfort experienced by application of the electroporation pulses.

Claims (9)

1. Apparatus for providing hair removal therapy to a patient, said apparatus comprising:

a high voltage pulse generator; and

an applicator electrically connected to said pulse generator, said applicator including a central electrode and an outer electrode surrounding the central electrode,

wherein said generator supplies pulses to said electrodes to create a electroporating field causing hair follicle death when said central electrode is placed into contact with a hair follicle, said apparatus further including a TENS system for providing a patient relief from discomfort caused by the application of electroporating pulses.

2. The apparatus of claim 1 wherein said TENS system includes a TENS generator for generation of TENS pulses and a synchronizing circuit for synchronizing the application to a patient of TENS pulses and electroporating pulses.

3. The apparatus of claim 2 wherein said applicator includes TENS electrodes for applying TENS therapy to the patient during electroporating treatment.

4. The apparatus of claim 3 wherein said TENS electrodes comprise said central and said outer electrodes.

5. The apparatus of claim 3 wherein said TENS electrodes comprise said central applicator electrode and a third electrode disposed outwardly from said outer electrode.

6. The apparatus of claim 5 wherein said third electrode has a substantially annular configuration.
