Abstract: A device for medical radiation therapy uses in the treatment area a deformable carrier mat (1) which can be placed on the patient. This carrier mat (1) has prefabricated mounting channels (7) running inside its mat plane to accommodate or to insert the guide sleeves (2), in which an essentially point-shaped radiation source (5) can be displaced and positioned. The carrier mat (1) is made of one piece from silicone or a silicone-like material which can be autoclaved. The carrier mat (1) is constructed from a plurality of spheres (9) or rounded, sphere-like, ball-shaped bodies (9a) which are provided adjacent to each other and are connected with each other by means of collar sections (8), while the mounting channels (7) run through the spheres (9) and/or the collar sections (8). Due to this even in the case of a minimum thickness of the carrier mat (1) a particularly good mobility and shape adaptability is present.

Abstract: A method for using stent which is a hollow, cylindrical structure made of a synthetic substance which becomes plastic and malleable in a temperature range from 45.degree. to 75.degree. Celsius. The stent is brought to the desired site, for example a stenosed section of an artery, by means of a heatable balloon catheter. The stent is heated at the site to be treated and whilst in the plastic state is expanded through dilatation of a balloon. After being cooled to body temperature the expanded stent retains the form achieved. The body fluids bring about complete biodegradation of the implanted stent.

Abstract: Device for the widening of blood vessels having a catheter (5) in whose front end area an elongate, inflatable balloon (6) is present, with the outside of the uninflated balloon (6) being wound round with a woven material (1) of such a length that its end edges (2), provided with a border, overlap. After introduction into the vessel and widening, the woven material serves as a vessel prosthesis.
