Aortic prosthetic devices
First Claim
1. A prosthetic device for use in the treatment of an aortic valve of a patient'"'"'s heart, said prosthetic device having a compressed state for transarterial delivery and being expandable to an expanded state for implantation, said prosthetic device comprising:
- an expandable support constructed so as to be implantable in the expanded state of the prosthetic device in an aortic annulus of the aortic valve;
an inner envelope having an upstream portion that lines the inner surface of the support, and a downstream portion which, when the prosthetic device is in the expanded state, is configured to extend into an aorta and defines a diverging conical section having a diameter that gradually increases from an upstream end of the diverging conical section to a downstream end of the section, which diverging conical section is configured to produce, during systole, a non-turbulent blood flow into the aorta with pressure recovery at the downstream end of the diverging conical section; and
a prosthetic valve coupled to the downstream portion of the envelope at the downstream end of the diverging conical section.

Abstract
A prosthetic device is provided for treatment of an aortic valve, having a compressed state for transarterial delivery and being expandable to an expanded state for implantation. The device includes an expandable support implantable in the expanded state of the prosthetic device in an aortic annulus, and an inner envelope having an upstream portion that lines the inner surface of the support, and a downstream portion which, when the prosthetic device is in the expanded state, extends into an aorta and defines a diverging conical section having a diameter that gradually increases from an upstream end of the section to a downstream end of the section. The section is configured to produce, during systole, a non-turbulent blood flow into the aorta with pressure recovery at the downstream end of the section. Other embodiments are also described.
