Apparatus comprising: a valve comprising a stent component and a valve component (800, 900, 1000) of the stent including the component (800, 900, 1000) of the stent a first section (802), a second section (804) configured to house the valve component and a third section (806) comprising at least one element (808, 814, 902, 1002) of binding, and may take the component (800, 900, 1000) of the stent and valve component a folded for placement and an expanded configuration after implantation and a system (2200, 2300, 2400, 2500 configuration , 2600) placement that can removably join the at least one element (808, 814, 902, 1002) connecting the valve stent system (2200, 2300, 2400, 2500, 2600) for positioning comprises a carrier (2222, 2514) of the stent to attachable removably the at least one element (808, 814, 902, 1002) of binding of stent valve and a cover (2206, 2506) outside, which in a closed position the outer cover (2206, 2506) surrounding the stent valve still attached to the carrier (2222, 2514) of the stent and therefore limits the expansion valve stent, wherein the cover (2206, 2506) and carrier (2222, 2514) stent are configured for relative movement with respect to one another to move from a closed position to a partially open position, to an open position, wherein in the partially open position, the stent valve is partially expanded but not separated from the carrier (2222, 2514) of the stent that the outer cap (2206, 2506) still surrounds the at least one element (808, 814, 90 2, 1002) connecting the valve stent and the carrier (2222, 2514) of the stent, while in the open position the cover (2206, 2506) Outside not limit the expansion of the stent valve and thus the valve stent is separated from the carrier (2222, 2514) of the stent and is expanded to the expanded configuration wherein the stent valve may be automatically separated system (2200, 2300, 2400, 2500, 2600) placement moving the cover ( 2206, 2506) outside her away from the element (808, 814, 9
