Abstract: The invention relates to a self-expandable stent, especially a pulmonary stent, with a proximal section, a middle section and a distal section arranged at a longitudinal axis of the stent, the stent having a dry valve made of bovine pericardium arranged at the middle section thereof, a skirt surrounding the dry valve at least at the middle section and made of one of bovine pericardium and polyester, wherein the stent further comprises eyelets arranged at a distal end at the distal section and/or a proximal end at the proximal section for fixing the stent at an artery, and wherein the stent comprises a frame composed of a plurality of arms forming the proximal, the middle and the distal section with the sections being interconnected, and the stent comprising a fixture area at the middle section of the frame with the arms being arranged in parallel to each other at the fixture area and the middle section comprising one or more fixture openings at said fixture area for fixing the valve at the frame.

Abstract: The present invention relates to an implant for placement in a cardiac vessel, the implant being able to be expanded from an un-deployed state to an expanded state in which the implant has a larger outer diameter than in the storage state, the implant having a main body with first and second ends and a central portion arranged between the first and second ends, the central portion of the implant having a larger outer diameter than the first and second ends of the implant when the implant is in the expanded state. The invention further relates to a delivery device for an implant and to a method of delivering an implant.

Abstract: The invention relates to a self-expendable stent for placement at a mitral annulus that is self-expandable from an undeployed state to a deployed state comprising a stent frame having at least a first section and a second section arranged at a longitudinal axis of the stent, wherein the stent frame is formed by a plurality of endless arms, the arms being connected to one another at connection points forming a web-like structure with diamond-shaped cells; a dry valve made out of bovine pericardium arranged at least at the second section of the stent with the dry bovine pericardium being configured to be rehydrated with a solution, a skirt surrounding the dry valve and comprising at least one of bovine pericardium and polyester, and wherein, in the expanded state, a maximum outer diameter of the first section is larger than a maximum outer diameter of the second section, and wherein at least at a transition between the first section and the second section some of the endless arms extend outwardly beyond the web

Abstract: The invention relates to a stent for placement at an aortic annulus that is expandable from an undeployed state to a deployed state comprising a stent frame having rows of cells with a proximal section and a distal section at a longitudinal axis of the stent, the stent frame being formed by a plurality of arms, the arms being connected to one another at connection points, and wherein the plurality of arms forms a plurality of diamond-shaped stent cells, in particular the rows of cells, formed of vertices at said connection points between the arms, a dry valve made out bovine pericardium arranged at least at the distal section of the stent with the dry bovine pericardium being configured to be rehydrated with a solution, a skirt surrounding the dry valve and comprising at least one of bovine pericardium and polyester, and one or more eyelets arranged at a distal end of some of the arms, with the eyelets being configured to fix the valve to the stent frame.

Abstract: The present invention relates to a method for treating biological tissue and a biological tissue obtained by the treatment method, and specifically to a method for treating biological tissue so as to suppress the calcification, risk of biofilm adherent over pericardium and strength reduction of the tissue due to treatment. The invention is also directed to bioprosthesis and transcatheter heart valves containing the biological tissue.
