The present invention relates to: a skin patch for an RF energy-using treatment device, the skin patch which has one surface in contact with the skin and has the other surface that is usable by making contact with an electrode of the RF energy-using treatment device, and which comprises a marker so as to guide treatment of the RF energy-using treatment device; an RF energy using treatment device using the skin patch; a control method therefor; and an RF energy-using skin treatment method. The skin patch for an RF energy-using treatment device, the RF energy-using treatment device using same, the control method therefor and the RF energy-using skin treatment method, according to the present invention, can guide the treatment location of a user from the patch attached to the skin, and control RF energy so as to improve treatment precision.

An LED facial mask incorporates a transparent light guide which distributes therapeutically useful frequencies of light over the skin of a user's face. Further, a USB connection port provides power. Alternate embodiments incorporate the mask device into alternate forms of wearable devices.

A pulsed laser skin treatment device is for laser induced optical breakdown of hair or skin tissue. The device has a light exit window to be placed against a surface to be treated such as skin during use. A feedback system is used for determining a state of contact between the light exit window and the surface. To this end the feedback system is capable of detecting a feedback signal representative for the state of contact. If the feedback signal or the state of contact is such that the risk of skin surface or device damage by the device operation is too high, the user or the device has a way to interrupt the treatment or to reduce light output to reduce or eliminate this risk.

The invention relates to a treatment device for dielectric harrier discharge plasma treatment of a wound surface or skin surface, having: a flexible, planar electrode assembly with at least one planar electrode (6, 6′) and a dielectric layer (5) which at least partially embeds the at least one electrode (6, 6′), has a contact side (7) facing the wound surface or skin surface and electrically shields the planar electrode (6, 6′) from the wound surface or skin surface such that only a dielectric barrier current can flow from the electrode (6, 6′) to the wound surface or skin surface; and a control device (2) which has a separate housing (25) and via which the electrode (6, 6′) can be connected to an operating voltage. The treatment device allows simpler wound treatment in that the assembly of electrode (6, 6′) and dielectric layer (5) is designed for uninterrupted contact with the wound surface or skin surface and that the housing (25) of the control device (2) can be fastened with a fastening device (3, 3′) to the body having the wound surface or skin surface.

Described herein are methods and systems for using the treatment tip apparatuses and high-voltage connectors with robotic surgical systems. For example, retractable treatment tip apparatuses (e.g., devices, systems, etc.) including one, or more preferably a plurality, of electrodes that are protected by a housing (which may be retractable) until pressed against the tissue for deployment of the electrodes and delivery of a therapeutic treatment, are disclosed. In particular, these apparatuses may include a plurality of treatment needle electrodes and may be configured for the delivery of nanosecond pulsed electric fields. Also described herein are high-voltage connectors configured to provide high-voltage energy, such as nsPEF pulses, from a generator to the retractable treatment tip apparatuses.

The present disclosure provides a method for treating clinical or pre-clinical skin damage in a skin field of a subject, wherein the skin field has been allocated a skin cancerization field index (SCR) score of at least 1 as determined by a process comprising the steps of: (i) assessing the number of keratoses in the skin field; (ii) assessing the thickness of the thickest keratosis in the skin field; and (iii) assessing the proportion of the field affected by clinical or subclinical skin damage. Based on the assessments made in (i), (ii) and (iii) the subject is optionally treated by at least one of (a) freezing one or more lesions, (b) shaving, curetting or surgically removing one or more lesions, (c) applying a topical treatment for actinic keratosis, basal cell carcinoma or squamous cell carcinoma, and (d) radiation therapy.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

An optic includes a first end, a fluorescent material, and a second end. The first end is adapted to transmit a first band of electromagnetic radiation to the fluorescent material. The fluorescent material is adapted to absorb the first band of electromagnetic radiation and emit a second band of electromagnetic radiation. The second end is adapted to contact the biological tissue and deliver the second band of electromagnetic radiation to treat the biological tissue.

Disclosed are kits for at least partly liquefying tissue. The kit may include a liquefaction promoting medium (LPM). The LPM may include a non-ionic surfactant; a zwitterionic surfactant; and an abrasive material. The kit may include instructions. The instructions may direct a user to treat a tissue of a living subject by: applying the LPM together with the abrasive material to the tissue of the living subject; and transmitting energy to the tissue of the living subject through the abrasive material in the presence of the LPM effective to cause at least partial dissolution of one or more components of the tissue of the living subject.

The present invention provides a device for rejuvenating a region of skin or mucosal tissue, comprising: a pulsed electromagnetic frequency generator; a plurality of electrodes in communication with the pulsed electromagnetic frequency generator and an RF tissue diathermy device. The electrodes apply the pulsed electromagnetic power and the RF tissue diathermy to the tissue, heating it such that one portion of the region of mucosal tissue is maintained at a predetermined temperature range T.sub.1 while another portion of the region of mucosal tissue is at least temporarily maintained at predetermined temperature range T.sub.2.
