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

The present invention relates to a method and apparatus for the uniform and simultaneous illumination by means of radiation of the interior surfaces of cavities for the purpose of observation and/or irradiation. In particular, such cavities may be not only hollow organ cavities, but also cavities in non-organic objects. The solution provides that the interior of the cavities is filled, at least in part, with a light scattering or dispersing medium and the dispersing medium is caused to shine or scatter light by means of one or a plurality of radiations or scattered light. With the integral irradiation used according to the present invention, two procedures are combined technologically, namely diagnosis and therapy of, for example, carcinoma in organ cavities which have been photosensitized by chemical substances, possibly on the basis of differences in decomposition of cancerous and normal tissue.
