<p>- The present invention relates to a prosthesis intended to be introduced into a body duct, comprising a flexible tube (2) intended to retain the normal passage cross-section of the body duct and a holding device (5) intended to immobilise the said tube (2) in position in the said duct (U), the said device (5) being connected to the distal end of the said tube (2) by connection means (4), while being arranged at a distance from the said end. - According to the invention, the holding device consists of a radially deformable structure (5) capable of passing from a first state in which its cross-section is at most equal to that of the body duct (U) into which it is to be introduced, to a second state in which its cross-section is such that the said structure (5) can bear on the inner wall of the said body duct, especially in the vicinity of the edge of an orifice in the body duct (U) emerging in a natural cavity. <IMAGE></p> |
