Abstract:
1. A frame structure for a prosthetic aortic heart valve, comprising: an annulus portion that is annular about a longitudinal axis and that is annularly collapsible and re-expandable, the annulus portion including a plurality of annularly spaced commissure post structures extending in a first direction parallel to the longitudinal axis, and a plurality of open-centered, closed perimeter first cells annularly positioned between the commissure post structures; an aortic portion that is annular about the longitudinal axis and annularly collapsible and re-expandable, the aortic portion being spaced from the annulus portion in the first direction; a plurality of strut members each having one end connected to the annulus portion and another end connected to a point on the aortic portion, for each of the points the aortic portion including a pair of arm members that begin at the point and diverge from one another in the first direction until each of the arm members connects to an arm member that started from an annularly adjacent one of the points, the aortic portion including no other structure between annularly adjacent ones of the arm members that connect to one another and that start from different ones of the points; and an open-centered, closed perimeter second cell below each of the commissure post structures, the second cells being more resistant to collapse than the first cells.
