| 摘要 |
Embodiments of the present invention provide prosthetic valves (200) having sealing members (212) on the external surface thereof. The sealing members of the present invention can be positioned on the prosthetic valve such that, when the prosthetic valve is implanted in a native annulus, each provided sealing member is located adjacent to a commissural point of the native valve leaflets. Because the sealing members are precisely oriented on the prosthetic valve, a physician can ensure that the sealing members are aligned with the commissural points of the native valve leaflets. In embodiments of the present invention, the prosthetic valve can have a waisted middle section, and the sealing members can be located in the waisted middle section such that the crimped diameter of the prosthetic valve is not negatively impacted by the sealing members. |
