Method of implanting a prosthetic valve

A method of implanting a prosthetic valve in a body vessel, comprising:

• providing a first expandable frame member having unexpanded and expanded configurations, the first frame member defining a sinus portion;
• providing a second expandable frame member having unexpanded and expanded configurations, the second expandable frame member having an attached graft member forming a valve adapted to permit fluid flow through said body vessel in a first direction and to substantially prevent fluid flow through said body vessel in a second, opposite direction;
• percutaneously delivering the first frame member to a point of treatment in said body vessel;
• deploying the first frame member at the point of treatment;
• percutaneously delivering the second frame member with the attached graft member to the point of treatment;
• after deploying the first frame member at the point of treatment, deploying the second frame member with the attached graft member at the point of treatment such that the second frame member is positioned radially inward of the first frame member within said body vessel to form said prosthetic valve.

A method of implanting a prosthetic valve in a body vessel, comprising:

• providing a first expandable frame member having unexpanded and expanded configurations, the first frame member having a first axial length and defining a sinus portion;
• providing a second expandable frame member having unexpanded and expanded configurations, the second expandable frame member having a second axial length and an attached graft member forming a valve adapted to permit fluid flow through said body vessel in a first direction and to substantially prevent fluid flow through said body vessel in a second, opposite direction, the first axial length being greater than the second axial length;
• percutaneously delivering the first frame member to a point of treatment in said body vessel;
• deploying the first frame member at the point of treatment;
• percutaneously delivering the second frame member with the attached graft member to the point of treatment;
• after deploying the first frame member at the point of treatment, deploying the second frame member with the attached graft member at the point of treatment such that the second frame member is positioned radially inward of the first frame member within said body vessel and such that the valve is positioned substantially adjacent the sinus portion to form said prosthetic valve.
