CA 2744399

An apparatus and a method are provided for the treatment of soft tissue. The apparatus includes a light source and at least two optical assemblies. Each of the optical assemblies includes at least one optical element and a light-transmitting contact surface configured to transmit a substantially uniform distribution of light therethrough. The apparatus further includes at least two optical transmission devices each disposed between the light source and a corresponding one of the at least two optical assemblies. The apparatus also includes a handpiece to which the at least two optical assemblies are attached, and which is adapted to bring the light- transmitting contact surfaces of the at least two optical assemblies in contact with soft tissue disposed there between. The method includes compressing and substantially flattening portions of the tonsil tissue between light-transmitting contact ] surfaces of two opposed light emitting optical assemblies, introducing light into an optical element of each of the optical assemblies; and irradiating the tonsil tissue by directing the light from the optical element through the light-transmitting contact surfaces to the tonsil tissue in a substantially uniform light distribution.

L'invention concerne un appareil et un procédé destinés au traitement de tissus mous. L'appareil comprend une source lumineuse et au moins deux ensembles optiques. Chacun des ensembles optiques comprend au moins un élément optique et une surface de contact transmettant la lumière configurée de façon à transmettre une répartition de lumière sensiblement uniforme à travers celle-ci. L'appareil comprend en outre au moins deux dispositifs de transmission optique, chacun d'eux étant disposé entre la source lumineuse et un ensemble correspondant parmi lesdits au moins deux ensembles optiques. L'appareil comprend également un manche auquel sont fixés lesdits au moins deux ensembles optiques et qui est prévu pour amener les surfaces de contact transmettant la lumière desdits au moins deux ensembles optiques en contact avec un tissu mou disposé entre celles-ci. Le procédé comporte les étapes consistant à comprimer et à aplatir sensiblement des parties du tissu des amygdales entre des surfaces de contact transmettant la lumière de deux ensembles optiques opposés émettant de la lumière, à introduire de la lumière dans un élément optique de chacun des ensembles optiques ; et à irradier le tissu d'amygdales en dirigeant la lumière provenant de l'élément optique à travers les surfaces de contact transmettant la lumière vers le tissu d'amygdales selon une répartition de lumière sensiblement uniforme.
