Title (EN) MEDICAL TREATMENT DEVICES HAVING ADJUSTABLE LENGTH AND/OR DIAMETER
(FR) DISPOSITIFS DE TRAITEMENT MÉDICAL À LONGUEUR ET/OU À DIAMÈTRE AJUSTABLES
Abstract:
(EN) A tissue treatment device (10) comprises an elongate shaft (12) having a distal end (13) and a heating element (22) disposed at the distal end (13) of the shaft (12). The heating element (22) has a proximal end (24) and a distal end (26). A first electrical pathway is configured to extend between a power source (18), the proximal end (24) of the heating element (22), and the distal end (26) of the heating element (22), and defines a first treatment length (LI) extending between the proximal and distal ends of the heating element (22). A second electrical pathway is configured to extend between the power source (18), the distal end (26) of the heating element (22), and an intermediate point (34) along the heating element (22) intermediate the proximal and distal ends thereof, and defines a second treatment length (L2) extending between the intermediate point (34) and the distal end (26) of the heating element (22).
(FR) La présente invention concerne un dispositif (10) de traitement de tissus comprenant une tige allongée (12) dotée d'une extrémité distale (13) et d'un élément chauffant (22) disposé au niveau de l'extrémité distale (13) de la tige (12). L'élément chauffant (22) comprend une extrémité proximale (24) et une extrémité distale (26). Un premier trajet électrique est conçu pour s'étendre entre une source d'alimentation (18), l'extrémité proximale (24) de l'élément chauffant (22), et l'extrémité distale (26) de l'élément chauffant (22), et définit une première longueur de traitement (L1) s'étendant entre les extrémités proximale et distale de l'élément chauffant (22). Un second trajet électrique est conçu pour s'étendre entre la source d'alimentation (18), l'extrémité distale (26) de l'élément chauffant (22), et un point intermédiaire (34) le long de l'élément chauffant (22) entre ses extrémités proximale et distale, et définit une seconde longueur de traitement (L2) qui s'étend entre le point intermédiaire (34) et l'extrémité distale (26) de l'élément chauffant.
