1. A valve prosthesis for implantation is a body channel, the prosthesis comprising a collapsible valvular structure (14), and an expandable frame (10, 10

  • ) on which said valvular structure (14) is mounted, said valvular structure (14) being composed of a valvular tissue compatible with the human body and blood, the valvular tissue being sufficiently supple and resistant to allow said valvular structure (14) to pass from a closed state to an open state to allow a body fluid exerting pressure on the valvular structure (14) to flow, wherein said valvular tissue forms a continuous surface and is provided with guiding means formed or incorporated within, said guiding means creating stiffened zones which induce said valvular structure (14) to follow a patterned movement in its expansion to said open state and closed state, providing therefore a structure sufficiently rigid to prevent eversion.
