Abstract: 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.

Abstract: A message display system comprises a bumper sticker kit including blank bumper stickers and sets of alpha/numeric display members. Each blank bumper sticker comprises a front display surface having registration indicia formed thereon and a back surface comprising an adhesive layer which is normally covered by a backing sheet. Each set of alpha/numeric display indicia includes a plurality of letters, numerals, etc. each comprising a front display surface of contrasting color relative to the front display surfaces of the blank bumper stickers and a back surface comprising an adhesive layer which is normally covered by a backing sheet.In the use of the invention, a message is formed on the front display surface of each blank bumper sticker by removing selected alpha/numeric display members from one of the sets and applying the display members to the front display surface of the blank bumper sticker in accordance with the registration indicia thereon.
