Abstract
Systems and methods for medical interventional procedures, including approaches to valve implant. In one aspect, the methods and systems involve a modular approach to treatment.
Claims20
A mitral valve replacement system configured to be implanted in multiple stages to treat a heart having a mitral valve including commissural clefts, a posterior leaflet, an anterior leaflet, and an annulus, comprising:
- an anchoring structure including a supra-annular retention structure and anchoring elements at least one of which is configured to engage sub-annular structure of the mitral valve to position the anchoring structure relative to the mitral valve without significantly interrupting the posterior leaflet or the anterior leaflet function;
- and
- an artificial valve configured to be received by the supra-annular retention anchoring structure after the anchoring structure is placed separately within the heart;
- wherein after engagement with the artificial valve the supra-annular retention structure remains spaced supra-annularly of the mitral valve.
A mitral valve replacement system configured to be implanted in multiple stages to treat a heart having a mitral valve including commissural clefts, a posterior leaflet, an anterior leaflet, and an annulus, comprising:
- an anchoring structure including a supra-annular ring-like structure and anchoring elements at least one of which is configured to engage sub-annular structure of the mitral valve to position the anchoring structure relative to the mitral valve without significantly interrupting the posterior leaflet or the anterior leaflet function;
- and
- an artificial valve configured to be received by with the supra-annular ring-like anchoring structure after the anchoring structure is placed separately within the heart;
- wherein after engagement with the artificial valve the supra-annular ring-like structure remains spaced supra-annularly of the mitral valve.
A mitral valve replacement system configured to be implanted in multiple stages to treat a heart having a mitral valve including commissural clefts, a posterior leaflet, an anterior leaflet, and an annulus, comprising:
- an anchoring structure including a supra-annular retention structure and anchoring elements at least one of which is configured to engage sub-annular structure of the mitral valve to position the anchoring structure relative to the mitral valve without significantly interrupting the posterior leaflet or the anterior leaflet function;
- and
- an artificial valve configured to sealingly engage with natural tissue and to be received by the supra-annular retention anchoring structure after the anchoring structure is placed separately within the heart;
- wherein after engagement with the artificial valve the supra-annular retention structure remains spaced supra-annularly of the mitral valve.
