An apparatus for the isotropic irradiation of cavity walls includes in a first channel of a catheter a light conducting fiber which has a cortically shaped tip for deflecting a light beam radially outwardly through a transparent portion of the catheter and a resiliently expandable sleeve tightly disposed around the catheter and having its interior in communication by a second channel with a fluid supply for expanding the sleeve so as form a light scattering structure whose scattering characteristics are adjustable dependent on the degree of sleeve expansion.

Apparatus for the isotropic irradiation of cavity walls

Apparatus for the isotropic emission and for the isotropic reception of light which includes a light conductor having a conical distal end with a scattering body mounted thereon in spaced relationship such that a cavity is formed between the light conductor end and the scattering body. The apparatus permits access to cavities such as hollow organs for internal laser phototherapy, for example.

Arrangement for the isotropic emission and isotropic reception of light

A method and an apparatus for the substantially uniform irradiation of the entire area of cavities from the inside. The apparatus comprises a light source and a layer comprising a material having a high-scatter capability, low transmission and low absorption, wherein said layer fits well to the interior surface of a cavity. The method comprises placing an area-covering layer along rhe cavity wall of the cavity to be irradiated with a material having a high diffusive reflection capability, low transmission, and low absorption capability to obtain a lined cavity; introducing a light source onto the interior of the lined cavity; and irradiating the lined cavity so that the light entering from the area-covering layer into the cavity wall is homogeneously distributed.
