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.

Claims

1. An expandable stent (10) for the positioning and anchoring of a valvular prosthesis (100) in an implantation site in the heart of a patient in the treatment of a narrowed cardiac valve or a cardiac valve insufficiency, wherein the stent (10) comprises a plurality of positioning arches (15a, 15b, 15c) configured to be positioned within a plurality of pockets (T) of the patient'"'"'s native heart valve and positioned on a first side of a plurality of native heart valve leaflets, and a plurality of retaining arches (16a, 16b, 16c) configured to be positioned on a second side of the plurality of native heart valve leaflets opposite the first side.
