Abstract
The present invention relates to a stent () for the positioning and anchoring of a valvular prosthesis () in an implantation site in the heart of a patient. Specifically, the present invention relates to an expandable stent for an endoprosthesis used in the treatment of a narrowing of a cardiac valve and/or a cardiac valve insufficiency. So as to ensure that no longitudinal displacement of a valvular prosthesis () fastened to a stent () will occur relative the stent () in the implanted state of the stent (), even given the peristaltic motion of the heart, the stent () according to the invention comprises at least one fastening portion () via which the valvular prosthesis () is connectable to the stent (). The stent () further comprises positioning arches () and retaining arches (), whereby at least one positioning arch () is connected to at least one retaining arch () via a first connecting land (). The stent () moreover comprises at least one auxiliary retaining arch () which connects the respective arms () of the at least one retaining arch () connected to the at least one positioning arch ().
