Abstract
A mitral valve therapy device effects the condition of a mitral valve annulus of a heart. The device includes an elongated member dimensioned to be placed in the coronary sinus of the heart adjacent the mitral valve annulus. The elongated member is flexible when placed in the heart in a first orientation to position the device in the coronary sinus adjacent the mitral valve annulus and relatively inflexible when rotated into a second orientation after the device is positioned in the coronary sinus adjacent to the mitral valve annulus to substantially straighten and increase the radius of curvature of the mitral valve annulus.
Claims26
A device that effects the condition of a mitral valve annulus of a heart comprising an elongated member dimensioned to be placed in the coronary sinus of the heart adjacent the mitral valve annulus, the elongated member having a relatively low resistance to flexure in a first direction and a relatively high resistance to flexure n a second direction.
A device that effects the condition of a mitral valve annulus of a heart comprising an elongated member dimensioned to be placed in the coronary sinus of the heart adjacent the mitral valve annulus, the elongated member being flexible when placed in the heart in a first orientation to position the device in the coronary sinus adjacent the mitral valve annulus and relatively inflexible when rotated into a second orientation after the device is positioned in the coronary sinus adjacent to the mitral valve annulus.
A method of effecting the condition of a mitral valve annulus of a heart, the method including the steps of:
- providing a mitral valve annulus therapy device including an elongated member that is flexible when placed in the heart in a first orientation and relatively inflexible when rotated into a second orientation;
- advancing the device into the coronary sinus of the heart with the device in the first orientation until the device is adjacent the mitral valve annulus within the coronary sinus;
- and
- rotating the device into the second orientation.
An assembly that effects the condition of a mitral valve annulus of a heart comprising:
- an elongated member dimensioned to be placed in the coronary sinus of the heart adjacent to the mitral valve annulus, the elongated member being flexible when placed in the heart in a first orientation to conform to the coronary sinus and relatively inflexible when rotated into a second orientation;
- and
- a push member configured to be releasably coupled to the elongated member that advances the elongated member into the coronary sinus adjacent to the mitral valve annulus.
