Embodiment Construction

[0042] The following detailed description is one of the best presently contemplated modes of carrying out the invention. This description is not for limiting purposes but merely for the purpose of illustrating the general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims.

[0043] The technology of this discipline relates primarily to mitral regurgitation treatment devices and means of placing and securing said devices within the human heart. The device includes an atrial portion and a ventricular portion. The atrial portion of the device "seats" in the mitral annulus area creating a "seal" to prevent leakage (backflow of blood from the left ventricle to the left atrium) from the area surrounding the device. The ventricular portion of the device includes a valve body and an anchoring structure. The anchoring structure may be partially or fully covered by fabric or tissue to create a "seal" against leakage. The val...

Abstract

A mitral valve replacement device is adapted to be deployed at a mitral valve position in a human heart. The device has an atrial flange defining an atrial end of the device, a ventricular portion defining a ventricular end of the device, the ventricular portion having a height ranging between 2 mm to 15 mm, and an annulus support that is positioned between the atrial flange and the ventricular portion. The annulus support includes a ring of anchors extending radially therefrom, with an annular clipping space defined between the atrial flange and the ring of anchors. A plurality of leaflet holders positioned at the atrial end of the atrial flange, and a plurality of valve leaflets secured to the leaflet holders, and positioned inside the atrial flange at a location above the native annulus.
