Abstract
A valvular prosthesis and method of using the prosthesis are disclosed. A valve apparatus is located within a stent apparatus, such that the prosthesis is deformable between a first condition and a second condition, in which the prosthesis has a reduced cross-sectional dimension relative to the first condition, whereby implantation of the prosthesis is facilitated when in the second condition.
Claims25
A valvular prosthesis comprising:
- a valve apparatus located within a stent apparatus to form a stented valve, the stented valve being deformable between a first condition a second condition, the stented valve having a cross-sectional dimension in the second condition that is less than a cross-sectional dimension of the stented valve when in first condition, whereby implantation of the stented valve is facilitated when in the second condition.
A method for implanting a valvular prosthesis having a valve apparatus mounted within a stent apparatus, comprising the steps of:
- reducing a cross-sectional dimension of the valvular prosthesis to a first condition;
- positioning the valvular prosthesis at a desired position within a length of tubular tissue while in the first condition;
- and
- increasing the cross-sectional dimension of the valvular prosthesis to a second condition, such that a portion of the valvular prosthesis engages the tubular tissue to mitigate axial movement of the prosthesis relative to the tubular tissue.
1 more element
A valvular prosthesis comprising:
- valve means for permitting substantially unidirectional flow of fluid through the valve means;
- and
- stent means disposed about the valve means for supporting the valve means, the stent means and valve means being deformable between a first condition a second condition, in which the prosthesis has a cross-sectional dimension that is less than a cross-sectional dimension thereof when in the first condition, whereby implantation of the prosthesis is facilitated when the stent means and valve means are in the second condition.
