Title (EN) DEVICES AND METHODS FOR RADIATION TREATMENT OF AN INTERNAL BODY ORGAN
(FR) DISPOSITIFS ET PROCEDES PERMETTANT D'IRRADIER ET DE TRAITER UN ORGANE CORPOREL INTERNE
Abstract:
(EN) The invention provides methods and devices for delivering low level radiation to inhibit neo-intimal hyperplasia following angioplasty or other intravascular procedures. In an exemplary method, a balloon (32) is inflated within a stenosed region of a blood vessel to produce a treated region. The balloon (32) is then deflated and a radioactive source (10) within a sleeve is aligned over the deflated balloon (32). The balloon (32) is again inflated at the treated region to engage the sleeve having the radioactive source (10) against the blood vessel within the treated region for from 1 minute to 40 minutes to deliver a sufficient dose of radiation to inhibit neo-intimal hyperplasia.
(FR) Cette invention se rapporte à des procédés et à des dispositifs conçus pour administrer une faible dose de rayonnement dans le but d'inhiber une hyperplasie aboutissant à une néo-intima à la suite d'une angioplastie ou de toute autre intervention intra-vasculaire. Selon un procédé préféré, on gonfle un ballonnet (32) à l'intérieur d'une région sténosée d'un vaisseau sanguin de manière à constituer une région traitée. On dégonfle ensuite le ballonnet (32) et on aligne une source radioactive (10), disposée à l'intérieur d'un manchon, au-dessus du ballonnet dégonflé (32). On regonfle alors ledit ballonnet (32) au niveau de cette région traitée de façon à amener le manchon contenant la source radioactive (10) au contact du vaisseau sanguin, à l'intérieur de la région traitée, pendant 1 à 40 minutes, de manière à administrer une dose de rayonnement suffisante pour inhiber une hyperplasie aboutissant à une néo-intima.
