1. A delivery system for percutaneously delivering a heart valve prosthesis to a site of a native heart valve, the delivery system comprising:
a delivery catheter including:
an outer sheath;
an inner shaft slidably disposed within the outer sheath; and
an orifice restriction mechanism attached to a distal portion of the inner shaft, wherein the orifice restriction mechanism has a first state and a radially expanded second state, and wherein the orifice restriction mechanism moves with the inner shaft in both the first state and the radially expanded second state; and
a heart valve prosthesis having a radially collapsed configuration and a radially expanded configuration, the heart valve prosthesis disposed within the outer sheath in the radially collapsed configuration in a delivery configuration of the delivery system,
wherein the orifice restriction mechanism is configured to be positioned within the native heart valve and is configured to temporarily replicate the operation of the native heart valve until the heart valve prosthesis is deployed within the native heart valve.
