CA 2656385

The invention provides a device and method for illuminating a body surface. A light source is optically coupled to the proximal end of a light guide and a light scatterer is optically coupled to the distal end of the light guide. The device includes a deployment mechanism that is configured to bring the light scatterer from a small caliber configuration in which the light scatterer is delivered to the body surface to a large caliber configuration in which the light scatterer irradiates the body surface. The invention may be used, for example, irradiate the periadventitial surface of an aneurysmal blood vessel.

L'invention prévoit un dispositif et procédé pour éclairer une surface de corps. Une source lumineuse est couplée optiquement à l'extrémité proximale d'un guide lumineux et un diffuseur de lumière est couplé optiquement à l'extrémité distale du guide lumineux. Le dispositif inclut un mécanisme de déploiement qui est configuré afin de faire passer le diffuseur de lumière d'une configuration à petit calibre dans laquelle le diffuseur de lumière est amené à la surface de corps à une configuration à grand calibre dans laquelle le diffuseur de lumière irradie la surface de corps. L'invention peut être utilisée, par exemple, pour irradier la surface périadventitielle d'un vaisseau sanguin anévrismal.
