Title
(EN) ENHANCED-FLEXIBILITY TRANSDUCER ARRAYS FOR DELIVERING TTFIELDS (TUMOR TREATING FIELDS)
(FR) RÉSEAUX DE TRANSDUCTEURS À FLEXIBILITÉ AMÉLIORÉE POUR LA DÉLIVRANCE DES CHAMPS TT (CHAMPS DE TRAITEMENT TUMORAL)
Abstract
(EN)
A transducer array for use in tumor-treating fields (TTFields) therapy is particularly suited for use in treating abdominal or thoracic cancers. The transducer array has features that increase its flexibility and adhesion to the patient's skin, including a branching configuration and a correspondingly branching top covering adhesive-backed layer. Additionally, a skin-level adhesive layer is provided beneath the flex circuit to which the electrode elements are attached, to help ensure thorough, lasting adhesion of the transducer array to the patient's skin over the course of treatment.
(FR)
Un réseau de transducteurs destiné à être utilisé dans la thérapie de champs de traitement tumoral (TTFields)) est particulièrement approprié pour utilisation dans le traitement de cancers abdominaux ou thoraciques. Le réseau de transducteurs présente des caractéristiques qui augmentent sa flexibilité et leur adhérence à la peau du patient, notamment une configuration de ramification et une couche à dos adhésif recouvrant le dessus de la ramification correspondante. En outre, une couche adhésive au niveau de la peau est disposée sous le circuit souple auquel les éléments d'électrode sont fixés, afin de faciliter une adhérence complète et durable du réseau de transducteurs sur la peau du patient pendant le traitement.
