Abstract: An ear-wearable electronic device includes aa shell having a uniquely-shaped outer surface that corresponds uniquely to an ear geometry of a user of the ear-wearable device. The device includes a mounting structure that is formed contiguously with the shell and intersects an inner surface of the shell. The mounting structure includes a mounting surface operable to fixably mount an interchangeable device to the shell. The mounting structure defines a void that extends from the inner surface to the outer surface of the shell. The mounting structure has a reference feature that is positioned relative to the outer surface of the shell such that the interchangeable device is located at a target orientation relative to the outer surface.

Abstract: In some embodiments, a prosthetic heart valve system includes a stent having a plurality of commissure attachment features, a cuff coupled to the stent, and a plurality of leaflets, the cuff and the plurality of leaflets forming a valve assembly, each of the plurality leaflets having two leaflet attachment regions, the leaflet attachment regions being folded adjacent the plurality of commissure attachment features.

Abstract: An ear-wearable electronic device includes a shell with a cable retention slot. The cable entrance slot has an interior end and an exterior end. A bend surface extends from the exterior end of the cable retention slot to an exterior surface of the shell. The bend surface aligned with a crux of a user's ear when the ear-wearable device is installed in an ear of the user's ear. The shell may include a uniquely-shaped outer surface that corresponds uniquely to an ear geometry of the user of the ear-wearable device.

Abstract: An ear-wearable electronic device includes a shell having a uniquely-shaped outer surface that corresponds uniquely to an ear geometry of a user of the ear-wearable device. The device includes an elongated sensor assembly. A mounting bridge is formed integrally with the shell and has a mounting surface that supports the elongated sensor assembly. An elongated void is in the shell that exposes the mounting surface of the mounting bridge. The shell includes an access void that extends from the inner surface to the outer surface of the shell near a first end of the mounting bridge. The access void is larger than a minor cross section of the elongated sensor assembly such that the elongated sensor assembly is able to pass through the access void and be held against the mounting surface.

Abstract: A prosthetic heart may include an expandable frame and prosthetic leaflets that each have a free edge, an attached edge having a contour, a first flat surface facing toward the frame, and a second flat surface facing away from the frame. A spacer fabric may be attached to each leaflet, the spacer fabric having a first surface, a second surface, and an inner matrix between the first and second surfaces.

Abstract: An ear-wearable electronic device comprises a shell having a uniquely-shaped outer surface that corresponds uniquely to an ear geometry of a wearer of the device. The shell comprises a window through a proximal portion of the shell and positioned at ear canal tissue when the device is deployed in the wearer's ear. An optical sensor, such as a photoplethysmograph (PPG) sensor, is disposed in the window. A biasing member has a uniquely-shaped outer surface that corresponds uniquely to a geometry of at least a portion of a pinna of the wearer's ear. The biasing member is configured to generate a biasing force sufficient to maintain static positioning of the optical sensor relative to the ear canal tissue during wearer body and jaw movement.

Abstract: An ear-wearable electronic device is housed within a shell. The shell includes an organically-shaped outer surface that corresponds uniquely to an ear geometry of a user of the ear-wearable device. The shell also has a faceplate void that has a curved and beveled perimeter edge. The faceplate void facilitates access to one or more devices installable into the shell. A faceplate is installed in the faceplate void. The faceplate has a beveled edge that mates with the perimeter edge. The faceplate includes an unbroken covering surface that matches the outer surface of the shell surrounding the faceplate void.
