Abstract
Abstract The invention concerns a kit ( 11 ) comprising a tubular endoprosthesis ( 19 ) having an inner surface ( 57 ) delimiting a channel ( 58 ) with longitudinal axis (X-X′). It comprises a prosthetic valve ( 17 ) designed to be implanted in the channel ( 58 ). The valve ( 17 ) comprises a supporting frame ( 25 ) having an outer surface ( 35 A, 35 B) designed to be pressed against the inner surface ( 57 ), and a flexible cover ( 39 ) connected to the frame ( 25 ). The inner surface ( 57 ) has at least two segments ( 65, 67 ) with variable cross-section along the longitudinal axis (X-X′). The segments ( 65, 67 ) form respectively a proximal stop ( 71 ) and a distal stop ( 73 ) to lock the axial displacement of the outer surface ( 35 A, 35 B) along the inner surface ( 57 ) along two opposite directions.
