| 摘要 |
<p>The invention relates to a device for radiation treatment of proliferative tissue surrounding a cavity in an animal body comprising: at least a first inflatable balloon system having a balloon wall for placement in said cavity; a supportive probe having an elongated, hollow body with a distal end connected with said at least first inflatable balloon system and a proximal end remaining outside said cavity; inflation means for inflating and deflating said at least first balloon system; radiation delivering means for placing at least one energy emitting source within said cavity for performing said radiation treatment, wherein said radiation delivering means comprise at least one hollow guidance channel for guiding said at least one energy emitting source inside said cavity. The invention aims to provide a device according to the above identified preamble, which balloon system completely conforms the outer surface of the cavity disregarding its outer shape or dimensions and which avoids the risk of tissue perfusion as no high pressures are exerted by the balloon system on the tissue surrounding the cavity. The device is according to the invention characterized in that said inflatable balloon system comprises two or more balloon chambers accommodated around the distal end of said supportive probe and wherein said at least one guidance channel is positioned between and outside adjacent balloon chambers. With this feature an inflated balloon system is obtained with a shape conformal to the body cavity shape.</p> |
