Abstract:
1. An assembly comprising a valve prosthesis and a prosthesis fixing device, comprising: a tubular element providing a lumen therethrough and intended to lie, when the prosthesis fixing device is in an implanted position, with an outside in contact with a wall part of the circulatory system and to accommodate said valve prosthesis inside the lumen of said tubular element, the tubular element having pins distributed around a periphery of the tubular element, said pins having pointed ends for penetrating the peripheral wall when the prothesis fixing device is in the implanted position, wherein the pointed ends face in radially outward direction of the tubular element, and each pin is angularly arranged on an arm which, via a bend line, is fixed by one end to the tubular element in a manner which permits swinging around said bend line, and wherein the arms and pins are movable, by swinging about the bend line, from an insertion position, in which the arms and pins are located inside the exposed lumen of the tubular element, into the implanted position in which at least the pins, viewed in the radial direction, project from the outside of the tubular element, the valve prosthesis comprising a cylindrical outer body fitting in the lumen of said tubular element, wherein the arms and pins are located within the longitudinal boundaries of the tubular element in the insertion position and in that the tubular element is provided with radial passages, viewed in radial direction of the tubular element, located alongside the pins and arms, such that, on swinging from the insertion position into the implanted position, the pins emerge through these passages and the arms are located within the passages.
