Abstract

A method of preparing biological tissue for use as a component of an implant, in particular as part of a heart valve prosthesis, which can be implanted by catheter. The biological tissue is subjected to a dimensional and structural stabilization step and is dried. For the dimensional and structural stabilization, a combination of a first, polyethylene glycol-containing solution and at least one second, glycerol-containing solution is used.
