Title (EN) PATCH, CONTROLLER, AND METHOD FOR THE PHOTODYNAMIC THERAPY OF A DERMAL LESION
(FR) PATCH, SYSTEME DE CONTROLE ET METHODE DE TRAITEMENT PHOTODYNAMIQUE D'UNE LESION DERMIQUE
Abstract:
(EN) An apparatus for photodynamic therapy (PDT) includes a cover (22) shaped to engage skin tissue (12) and a fiber optic panel (31) housed within the cover (22). Hydrogel (26) is located within the cover (22) and is in intimate physical and optical contact with the fiber optic panel (31) for optically coupling light from the fiber optic panel (31) to the skin tissue (12). The hydrogel (26) engages the stratum corneum (14) and hydrates and softens the stratum corneum (14) to enhance its optical transmissiveness to facilitate the transmission of light therethrough and to enhance its chemical transmissiveness to facilitate the transmission therethrough of photopharmaceuticals (28, 54) for treatment of a dermal lesion (10).
(FR) L'invention concerne un appareil de traitement photodynamique (TPD) qui comprend un couvercle (22) ayant une forme lui permettant de prendre appui sur le tissu cutané (12), et un faisceau de fibres optiques (31) logé dans le couvercle (22). Un hydrogel (26) disposé à l'intérieur du couvercle (22) est en contact physique et optique intime avec le faisceau de fibres optiques (31) de façon à permettre le couplage optique de la lumière provenant du faisceau (31) avec le tissu cutané (12). L'hydrogel (26) entre en contact avec le stratum corneum (14), qu'il hydrate et assouplit pour améliorer sa transmissivité optique afin de faciliter la transmission de la lumière et pour améliorer sa transmissivité chimique afin de faciliter la transmission de médicaments photosensibles (28, 54) en vue du traitement d'une lésion dermique (10).
