The flexible valve structure can comprises a first leaflet, a second leaflet, and a valve orifice between the first leaflet and the second leaflet.

Each leaflet attachment zone on the leaflet frame has substantially the shape of an isosceles trapezoid having two leaflet sides, a leaflet base and a leaflet free edge opposite the leaflet base.

In a laminated core for a transformer or other electrical apparatus, at least one lamination e.g. (10) has a sensor applied to it, the sensor being disposed at least partially between that lamination and an adjacent lamination.

A valve device includes a leaflet (14) and a means (12) for biasing the leaflet in an open configuration.

The two leaflet sides diverge from the leaflet base, wherein the leaflet base is substantially flat.

Each sheet is of an airtight plastics inner lamina and a fibrous polyester-cotton outer lamina.

The system (10) allows positive transfer of literature (34) into an erected carton (32) and wrap around of literature about the product.

The face (2) of the package adjacent to the leaflet is perforated so that it may be torn back to reveal the leaflet when the package is opened.

It is intended to provide a cultured corneal endothelial sheet which is expected as having a high therapeutic effect and a method of producing the same.

That sheet shall be given to the third-country national.

The mesoderm, also called the mesoblast, is the intermediary embryonic layer between the external layer (ectoderm) and the internal layer (endoderm).

That sheet shall be given to the third-country national.

In plasma membranes, phosphatidylserine is normally present only on the inner leaflet but is "flipped" to the outer leaflet upon the presence of cell damage.

The leaflet is then pierced with tip of the needle.

At least one mobile leaflet member on the leaflet assembly is sized and configured to assume orientations that change according to blood flow direction.
