The stent-valves include a stent component having a first flared end region and a second end, a plurality of leaflets coupled to the stent, and a sealing element coupled to the first end region. ## Claims ### Claim 1 A prosthetic heart valve, comprising: a stent having a first end region and a second end region; wherein the first end region is flared and includes a first ring of cells adjacent a first end of the stent; one or more attachment elements disposed at the second end region, the attachment elements being designed to attach the stent to a delivery catheter; a plurality of leaflets coupled to the stent; and a sealing member coupled to the first end region; wherein at least a portion of the sealing member is disposed outside of the stent and covers the first ring of cells, wherein the sealing member has an inflow edge disposed at an inflow end of the stent and a free floating edge that is axially spaced apart from the inflow edge and positioned at a proximal end of the sealing member. ### Claim 2 (depends on 1) The prosthetic heart valve of claim 1, wherein the first end region is an inflow end region. ### Claim 3 (depends on 1) The prosthetic heart valve of claim 1, wherein the sealing member has an outflow edge axially spaced apart from the inflow edge. ### Claim 4 (depends on 1) The prosthetic heart valve of claim 1, wherein the sealing member includes a plurality of flaps. ### Claim 5 (depends on 1) The prosthetic heart valve of claim 1, wherein the sealing member has an outflow edge, and wherein a plurality of cuts are disposed along the outflow edge. ### Claim 6 (depends on 5) The prosthetic heart valve of claim 5, wherein the plurality of cuts defines a plurality of alternating projections and recesses in the sealing member. ### Claim 7 (depends on 1) The prosthetic heart valve of claim 1, wherein the sealing member is conformable. ### Claim 8 A prosthetic heart valve, comprising: a stent having a substantially conical inflow region and an outflow region, wherein the stent comprises a framework forming a plurality of cells; a plurality of leaflets coupled to the stent; a multi-component fabric reinforcement, wherein each component has a trapezoid geometry; a sealing member coupled to the substantially conical inflow region, the sealing member having an inflow edge disposed at an inflow end of the stent; and wherein the outflow region includes alternating axial peaks and valleys; wherein the sealing member extends along an outer surface of the framework and covers at least an end row of cells proximate the inflow end, the sealing member having a free floating edge that is axially spaced apart from the inflow edge and positioned at a proximal end of the sealing member. ### Claim 9 (depends on 8) The prosthetic heart valve of claim 8, wherein the free floating edge of the sealing member is an outflow edge. ### Claim 10 (depends on 8) The prosthetic heart valve of claim 8, wherein the sealing member includes a plurality of flaps. ### Claim 11 (depends on 9) The prosthetic heart valve of claim 9, wherein the sealing member includes a plurality of cuts disposed adjacent to the outflow edge. ### Claim 12 (depends on 11) The prosthetic heart valve of claim 11, wherein the plurality of cuts defines alternating axial peaks and valleys in the outflow edge. ### Claim 13 A prosthetic heart valve, comprising: a stent having a flared inflow region, a central region, and an outflow region; a plurality of leaflets coupled to the stent; a multi-component fabric reinforcement, wherein each component has a trapezoid geometry; and a sealing member coupled to the flared inflow region, the sealing member having an inflow edge and an outflow edge, wherein the outflow edge defines a free-floating edge; wherein the stent includes an annular groove and the free-floating edge of the sealing member is positioned within the annular groove. ### Claim 14 (depends on 13) The prosthetic heart valve of claim 13, wherein the sealing member includes a plurality of flaps. ### Claim 15 (depends on 13) The prosthetic heart valve of claim 13, wherein the sealing member includes a plurality of cuts. ### Claim 16 (depends on 13) The prosthetic heart valve of claim 13, wherein a plurality of cuts are disposed along the outflow edge. ### Claim 17 (depends on 16) The prosthetic heart valve of claim 16, wherein the plurality of cuts defines a plurality of alternating projections and recesses in the sealing member.
