Abstract
A prosthetic valve device and a method of forming a frame thereof. The method may include cutting a pattern into a tube having a first inner diameter and an axis, the pattern having a plurality of post pattern sections arranged on the tube in a circumferentially spaced-apart manner and a plurality of lattice pattern sections extending between the post pattern sections. The method may further include diametrically expanding the tube until the tube has a second inner diameter that is greater than the first inner diameter. The expanded tube may have a plurality of axial posts arranged on the expanded tube in a circumferentially spaced-apart manner and a plurality of lattices having open cells extending between the axial posts.

A method of forming a tubular body of a frame for a prosthetic valve device, the method comprising:
- a) cutting a pattern into a tube having a top edge, a bottom edge, a first inner diameter, and an axis, the pattern comprising a plurality of post pattern sections arranged on the tube in a circumferentially spaced-apart manner and a plurality of lattice pattern sections extending between the post pattern sections, wherein the pattern is formed entirely of linear slits that extend substantially parallel to the axis, wherein all of the linear slits of the pattern are arranged in axial columns;
- and
- b) diametrically expanding the tube until the tube has a second inner diameter that is greater than the first inner diameter, wherein the expanded tube comprises a plurality of axial posts arranged on the expanded tube in a circumferentially spaced-apart manner and a plurality of lattices having open cells extending between the axial posts, each of the plurality of axial posts extending from the top edge of the tube to the bottom edge of the tube;
- wherein each of the axial posts is defined between a first axial column of the linear slits and a second axial column of the linear slits, wherein each one of the linear slits of the first axial column is aligned with one of the linear slits of the second axial column such that a plane perpendicular to the axis of the tube intersects the one of the linear slits of the first axial column and the one of the linear slits of the second axial column, and wherein each of the post pattern sections comprises a central axial column, each of the linear slits of the central axial column being at least partially circumferentially aligned with axial gaps that exist between the linear slits of each of the first and second axial columns.
A method of forming a tubular body of a frame for a prosthetic valve device, the method comprising:

- diametrically expanding the tube until the tube has a second inner diameter that is greater than the first inner diameter, wherein the expanded tube comprises a plurality of axial posts arranged on the expanded tube in a circumferentially spaced-apart manner and a plurality of lattices having open cells extending between the axial posts
- wherein the pattern is formed entirely of linear slits that extend substantially parallel to the axis;
- wherein each of the axial posts is defined between a first axial column of linear slits and a second axial column of linear slits, the linear slits of the first axial column being spaced apart from one another by first axial gaps, and the linear slits of the second axial column being spaced apart from one another by second axial gaps;
- and
- wherein each of the post pattern sections comprises a central axial column of linear slits, each of the linear slits of the central axial column being at least partially aligned with at least one of the first and second axial gaps.
A method of forming a frame for a prosthetic valve device, the method comprising:
- providing a tubular body having a top edge, a bottom edge, a first inner diameter, and an axis;
- cutting a pattern of linear slits into the tubular body;
- diametrically expanding the tubular body to form a frame having a second inner diameter that is greater than the first inner diameter, wherein the frame comprises a plurality of axial posts arranged in a circumferentially spaced-apart manner and a plurality of lattices having open cells extending between the axial posts;
- and
- the pattern comprising a plurality of central axial columns of linear slits, each of the linear slits of each of the plurality of central axial columns of linear slits expanding to form openings in the axial posts when the tubular body is diametrically expanded to form the frame.
