Disposable protection system for capacitive radiofrequency delivery devices
View Patent ↗A disposable device designed to enhance the safety of capacitive radiofrequency therapies is described that is able to prevent risks arising from lesions present on the dielectric surface of the insulated electrode or on the stratum corneum of the skin, as well as risks arising from the use of technologies placed on the market before the certification of non-cytotoxicity of the parts applied to the patient (ISO 10993: 2018) was required, as well as the risks of contamination of parts applied in therapies previously performed on other patients.
1 . An electrically insulating protective shield for an insulated electrode of a capacitive RF delivery device that must be applied in direct physical contact with the skin surface of a patient to be treated; said insulated electrode comprising a central solid electrically conductive core entirely enclosed within a first insulating dielectric material coating, said insulating protective shield made of non-cytotoxic dielectric material and configured and specifically adapted as a removable dielectric positioned between and in direct physical contact with the first insulating dielectric material coating and the skin surface of the patient to be treated; wherein, when in use, the insulating protective shield forms a second separate dielectric barrier over the first dielectric coating, thereby providing two distinct dielectric layers interposed between the conductive core of the insulated electrode and the skin surface of the patient to be treated.
2 . The protective shield according to claim 1 , characterized in that the protective shield is disposable.
3 . The protective shield according to claim 1 , having a thickness of 0.01-20 mm.
4 . The protective shield according to claim 1 , in rigid, semi-rigid or flexible form.
5 . The protective shield according to claim 1 , hot-molded or injection-molded, milled or molded.
6 . The protective shield according to claim 1 , made of PVC or polyoxymethylene (POM), polysulfone (PSU), polyphenylsulfone (PPSU), polyetheretherketone (PEEK).
7 . The protective shield according to claim 1 , in the form of a cover cap specifically adapted to the shape of an insulated electrode of a capacitive RF delivery device.
8 . The protective shield according to claim 1 , in the form of a film, membrane or dielectric sheet to be applied on the stratum corneum of the patient.
9 . A cosmetic method comprising interposing the protective shield according to claim 1 between the insulated electrode of a capacitive RF delivery device and the patient's skin area to be treated; said insulated electrode consisting of a central solid electrically conductive core entirely enclosed within a first insulating dielectric material coating, wherein the insulating protective shield is placed between and in direct contact with the insulating dielectric material coating of the insulated electrode and the skin surface of a patient to be treated; wherein, during use, the protective shield provides a second separate dielectric barrier forming a double electrical insulation between the conductive core and the patient's skin.
10 . A method for the medical treatment of injured or non-intact skin tissues by applying capacitive RF, said method comprising interposing the protective shield according to claim 1 between the insulated electrode of a capacitive RF delivery device and the patient's skin area to be treated; said insulated electrode consisting of a central solid electrically conductive core entirely enclosed within a first insulating dielectric material coating, wherein the insulating protective shield is placed between and in direct contact with the insulating dielectric material coating of the insulated electrode and the skin surface of a patient to be treated; wherein, during use, the protective shield provides a second separate dielectric barrier forming a double electrical insulation between the conductive core and the patient's skin.
11 . The protective shield according to claim 3 , having a thickness of 0.1-5 mm.
