Claim Text:
1. A system for replacing a heart valve, having an annulus and a plurality of native leaflets, with a prosthetic valve, the system comprising: a low-profile prosthetic valve expandable within a valve annulus to permanently replace the heart valve, the prosthetic valve including one or more prosthetic leaflets; at least one temporary valve (TV) including a central delivery catheter and an occluder configured to be reversibly expanded in a vessel in proximity to the annulus to partially occlude the vessel, the TV being configured to be delivered and removed percutaneously with the occluder in a contracted state; and at least one low-profile stent configured to be deployed through the central delivery catheter into the annulus of the heart valve, wherein the at least one low-profile stent includes a plurality of low-profile stents configured to be delivered and concentrically deployed in the annulus, the low-profile stents being sequentially delivered and deployed through the central delivery catheter, wherein each of the plurality of low-profile stents has a radial strength insufficient to fully open the plurality of native leaflets, wherein the plurality of low-profile stents, when deployed into the annulus of the heart valve, together has a total radial strength sufficient to fully open the plurality of native leaflets to place the annulus in an open configuration, prevent recoil of the annulus and the plurality of native leaflets of the valve, and assume substantially all of a mechanical load sufficient to maintain the open configuration of the annulus, wherein the prosthetic valve is configured to serve as a framework to support the one or more prosthetic leaflets therein, wherein the prosthetic valve alone has a radial strength insufficient to serve to maintain the open configuration of the annulus, and wherein the prosthetic valve is configured to be deployed and securely anchored inside the plurality of low-profile stents when deployed into the annulus, the deployed plurality of low-profile stents being configured to house the prosthetic valve.
