A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable valve support. If desired, one or more anchor may be used. The valve support, which entirely supports the valve annulus, valve leaflets, and valve commissure points, is configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the assembly is properly positioned. The anchor engages the lumen wall when expanded and prevents substantial migration of the valve assembly when positioned in place. The prosthetic valve assembly is compressible about a catheter, and restrained from expanding by an outer sheath. The catheter may be inserted inside a lumen within the body, such as the femoral artery, and delivered to a desired location, such as the heart. When the outer sheath is retracted, the prosthetic valve assembly expands to an expanded position such that the valve and valve support expand within the deficient native valve, and the anchor engages the lumen wall.
A prosthetic valve assembly for use in replacing a deficient native valve, the valve assembly comprising:
A method of replacing a deficient native valve comprising the steps of:
A prosthetic valve assembly configured for endoluminal delivery to replace a deficient native valve, the valve assembly comprising an axial valve support portion configured to support a prosthetic valve having at least one leaflet and configured to expand in situ to push the residual native valve components against the native annulus and surrounding tissue so as to prevent substantial interference with the positioning and/or operation of the prosthetic valve by any residual components of the native valve, including calcified native components, said support portion comprising a first section selectively dimensioned to expand when deployed in situ substantially no greater than a preset diameter to maximize coaptivity of the prosthetic valve leaflets and to prevent significant regurgitation, and a second section expandable to a diameter greater than the first section.
A prosthetic valve assembly configured for percutaneous delivery to replace a deficient native valve, the valve assembly comprising an axial valve support portion comprising a central band comprising a plurality of expandable cells, the support portion configured to support a prosthetic valve having a plurality of leaflets and to prevent substantial interference with the positioning and/or operation of the prosthetic valve by any residual components of the native valve, including calcified native components, said support portion comprising a first section selectively dimensioned to expand when deployed in situ substantially no greater than a preset diameter to maximize coaptivity of the prosthetic valve leaflets and to prevent significant regurgitation.
A prosthetic valve assembly comprising an axial valve support portion configured to support a prosthetic valve having a plurality of leaflets and to prevent substantial interference with the positioning and/or operation of the prosthetic valve by any residual components of the native valve, including calcified native components, said support portion comprising
