METHOD OF RECONFIGURING A MITRAL VALVE ANNULUS

摘要

Disclosed are systems and methods relating to an implant configured for reshaping a mitral valve. The implant comprises a plurality of struts with anchors for tissue engagement. The implant is compressible to a first, reduced diameter for transluminal or transapical navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter to embed its anchors to the tissue surrounding and/or including the mitral valve. The size and/or shape of the implant may then be adjusted, pulling mitral annulus tissue radially inwardly, and restrained in the adjusted configuration to improve mitral valve function.

1. A method of reconfiguring a mitral valve annulus, comprising:
positioning an implant having a first diameter into a left atrium, the implant comprising a frame having a proximal end, a distal end, a pair of struts joined at an apex, and a plurality of anchors near the distal end; expanding the positioned implant to a second diameter larger than the first diameter; connecting the expanded implant to tissue surrounding a mitral valve by embedding the plurality of anchors into the tissue; adjusting an angle between the pair of struts to contract the implant; and positioning a restraint on the pair of struts to retain the angle.
