Abstract
A transcatheter heart valve prosthesis includes an annular frame including a plurality of struts. The plurality of struts define a first plurality of cells arranged along a first cell axis and a second plurality of cells arranged along a second cell axis. First cell is aligned with a first ostia and a second cell is aligned with a second ostia. A prosthetic valve is attached to the frame and includes a plurality of leaflets and a commissure. Methods of rotationally aligning a transcatheter heart valve prosthesis within a native heart valve are provided.
Claims20
A transcatheter heart valve prosthesis comprising:
- an annular frame extending along a longitudinal axis between an inflow end of the transcatheter heart valve prosthesis and an outflow end of the transcatheter heart valve prosthesis, the annular frame comprising a plurality of struts and configured to be adjustable between a radially-collapsed position and a radially-expanded position, the plurality of struts defining:
- a first plurality of cells arranged along a first cell axis that is substantially parallel to the longitudinal axis, the first plurality of cells comprising a first cell at a first axial location, the first cell configured to be aligned with a first ostia such that a first radial axis intersects the longitudinal axis and passes through the first cell and the first ostia;
- and
- a second plurality of cells arranged along a second cell axis that is substantially parallel to the longitudinal axis, the second plurality of cells spaced circumferentially apart from the first plurality of cells, the second plurality of cells comprising a second cell at the first axial location, the second cell configured to be aligned with a second ostia such that a second radial axis intersects the longitudinal axis and passes through the second cell and the second ostia;
- and
- a prosthetic valve attached to the frame and comprising a plurality of leaflets, the prosthetic valve comprising a commissure where a first pair of leaflets of the plurality of leaflets are attached, the commissure attached to the frame and lying within a third cell axis that is substantially parallel to the longitudinal axis, the third cell axis positioned circumferentially between the first cell axis and the second cell axis such that a first separating distance circumferentially separates the first cell axis from the third cell axis and a second separating distance circumferentially separates the second cell axis from the third cell axis, the first separating distance different than the second separating distance.

A method of rotationally aligning a transcatheter heart valve prosthesis within a native heart valve, the method comprising:
- determining a position of a first ostia and a second ostia within the native heart valve;
- loading the transcatheter heart valve prosthesis in a first rotational orientation onto a delivery assembly, the first rotational orientation based on the position of the first ostia and the second ostia;
- percutaneously delivering the transcatheter heart valve prosthesis to the native heart valve such that a first cell defined by one or more struts of the transcatheter heart valve prosthesis is aligned with the first ostia and a first unimpeded path extends from the first ostia and through the first cell, and a second cell defined by one or more of the struts is aligned with the second ostia and a second unimpeded path extends from the second ostia and through the second cell.
