Title
(EN) DEVICE FOR HEAT TREATMENT OF BODY TISSUE
(FR) DISPOSITIF SERVANT A EFFECTUER LE TRAITEMENT THERMIQUE D'UN TISSU CORPOREL
Abstract
(EN)
Transurethral catheter (10) for the heat treatment of body tissue surrounding the catheter, including an elongated light carrier (11). A light receiving and light distributing elongated light probe (12) is operatively connected to said light carrier (11), and the light probe (12) comprises light reflecting surfaces (13) for preventing received light from escaping from the probe (12). At least one light emitting section (14) is formed in the probe (12) for emitting light into said body tissue.
(FR)
Cathéter transurétral (10) servant à effectuer le traitement thermique d'un tissu corporel entourant le cathéter, et comprenant un élément allongé (11) conducteur de lumière. Une sonde (12) allongée recevant et distribuant de la lumière est accouplée à cet élément allongé (11) et présente des surfaces réfléchissantes (13) permettant d'empêcher la lumière reçue de s'échapper de la sonde (12). Au moins une partie (14) émettant de la lumière est située dans la sonde (12) et sert à émettre de la lumière vers l'intérieur dudit tissu corporel.
