Abstract: The present invention relates to a method and an apparatus for guiding an irradiation equipment (2) located outside a human body (1) or an animal body. The method comprises the steps of identifying, in an image (4), a three-dimensional element (7) visible in the image (4), said three-dimensional element (7) has been in position in, or being inserted into, a cavity of the human body (1) or the animal body, establishing, in the image (4), a preliminary position of the three-dimensional element (7) visible in the image (4) in relation to a reference, establishing a preliminary position of the irradiation equipment (2) in relation to the reference, and adjusting the irradiation equipment (2) in response to the position the three-dimensional element (7).

Abstract: The present invention relates to a stent (1?) for use in a tubular organ of a body. The stent (1?) comprises a first part (8) to be positioned in a diseased part (2) of the organ and acting as a stentbody therein, and a second part (10, 10?, 40) to be positioned in a non-diseased part (6) of the organ and acting as an anchoring element therein. The two parts (8; 10, 10?, 40) are being designed as tubular members interconnected at the ends facing one another by a flexible, axially rigid connecting part (9), at least said second part (10, 10?, 40) having memorized therein a capacity to expand radially after an increase in temperature, thereby providing anchorage of the second part (10, 10?, 40) at a determined distance away from the diseased part (2) of the organ. The present invention further relates to a catheter (12, 50) and a method for using the stent (1?) and catheter (12, 50).
