1. A delivery system, comprising:
- a catheter shaft;
a prosthetic valve coupled to the catheter shaft, the prosthetic valve including a stent and a plurality of leaflets coupled to the stent;
wherein the stent has an inflow end region and an outflow end region;
a sealing member coupled to the inflow end region; and
one or more fixation elements disposed along the stent, the one or more fixation elements being designed to releasably secure the stent to the catheter shaft,wherein the sealing member includes a polymer.
