An improved device for delivery of photo-energy from a light source (14), such as a laser, into a uterine cavity for photodynamic therapy, is comprised of a plurality of optic fibers (24, 26, 28) which are bundled together and inserted into the uterine cavity by means of a cannula (18). Withdrawing of the cannula (18) allows the optic fibers (24, 26, 28) to splay or diverge within the cavity. Different portions of the distal tips of the optic fibers (24, 26, 28) are provided with a light diffusing tip, the remainder of the fiber optics being non-diffusing.

Dispositif perfectionné permettant de transmettre de l'énergie lumineuse depuis une source lumineuse (14), telle qu'un laser, à une cavité intra-utérine dans le cadre d'une thérapie photodynamique. Ce dispositif comprend une pluralité de fibres optiques (24, 26, 28) assemblées sous forme de faisceau et introduites dans la cavité utérine par l'intermédiaire d'une canule (18). L'enlèvement de la canule (18) permet aux fibres optiques (24, 26, 28) de s'étaler ou de diverger les unes par rapport aux autres à l'intérieur de la cavité. Différentes parties des extrémités distales desdites fibres (24, 26, 27) présentent des propriétés de diffusion de lumière, les parties restantes des fibres optiques ne diffusant pas la lumière.
