Abstract: The present technology is a prosthetic heart valve device, and related systems and methods, for treating a native valve of a human heart having a native annulus and native leaflets. One embodiment comprises a valve support, a prosthetic valve assembly within the valve support, and an anchoring member having an upstream portion and a downstream portion. The device further includes an extension member coupled to the fixation frame and extending radially outward therefrom. The extension member includes a plurality of discrete fabric segments having a first end at the anchoring member and a second end spaced apart from the anchoring member, wherein each discrete fabric segment includes lateral edges extending from the first end to the second end of the discrete fabric segment. The discrete fabric segments are configured to move circumferentially relative to each other.

Abstract: Double patterning is achieved with a single reticle while maintaining the integrity of in-scribe patterns and without blading the reticle. In-scribe structures may or may not be double patterning. For example, elements such as electrical test structures might have features that are so closely spaced that double pattering is desired. However, elements such as optical alignment marks might not require double patterning. For those elements for which double patterning is not desired, a first sub-array of the reticle has a pattern for the element, whereas the corresponding location in a second sub-array has a blank. By the corresponding location, it is meant the location on the reticle that would be exposed to the same target region to which the element would be exposed if the reticle were used for double patterning. Thus, the blank prevents target region from being exposed more than once.
