Zusammenfassung:Bioprosthetic component for an implant, based on a native or optionally modified biological material, is claimed. The surface of the biological material has at least one zone, due to a separate stability-increasing treatment of a part of the surface, which exhibits an increased mechanical stability compared to the mechanical stability before the stability-increasing treatment. The zones have increased mechanical stability of = 40% of the surface and the properties of the remaining zones of >= 60% of the surface. Bioprosthetic component for an implant, based on a native or optionally modified biological material, is claimed. The surface of the biological material has at least one zone, due to a separate stability-increasing treatment of a part of the surface, which exhibits an increased mechanical stability compared to the mechanical stability before the stability-increasing treatment. The zones have increased mechanical stability of = 40% of the surface and the properties of the remaining zones of >= 60% of the surface, which are substantially unaltered before and after the stability-increasing treatment, based on the total surface of the bioprosthetic component. An independent claim is also included for producing a bioprosthetic component for an implant, preferably a biological heart valve, preferably a heart valve leaflet, comprising subjecting a part of the surface of the bioprosthetic component for an implant to a separate stability-increasing treatment, optionally a separate stability-increasing chemical and/or thermal treatment, to produce zones having an increased mechanical stability compared to the mechanical stability before the stability-increasing treatment, where the zones with increased mechanical stability are formed by maximum proportion of up to 40% of the surface and the properties of the remaining zones with a proportion of at least 60% of the surface are unaltered by the stability-increasing treatment.
