  • Publication number: 20230363886
    Abstract: A stent graft system includes a first layer of graft material, a second layer of graft material, one or more stent members, one or more reducing belts, and a release wire. The one or more stent members are located between the first layer of graft material and the second layer of graft material. The second layer of graft material is formed to have a corresponding channel over each of the one or more stent members. The one or more reducing belts each include a loop at both ends and each is located in a corresponding channel around a corresponding one of the stent members. The release wire passes through both loops of each of the one or more reducing belts when the one or more stent members are in a compressed state. Pulling the release wire allows for the stent graft system to radially expand.

  • Publication number: 20200281711
    Abstract: A stent graft system includes a stent graft, a radially expandable scaffold, and an inflatable fill structure. The stent graft includes a body portion with a plurality of pleated sections that are configured to be extended from a telescopically compressed state to a longitudinally extended state. The radially expandable scaffold is attached to a top of the body portion, and has one or more fixation elements for penetrating into an aortic wall. The inflatable fill structure is attached at a top of the body portion and is configured to expand in a longitudinal direction as the body portion is extended in the longitudinal direction. The inflatable fill structure is also configured to expand in a radial direction to contact an inner surface of a blood vessel.

  • Publication number: 20200163750
    Abstract: A method for forming pleats in a stent graft, includes forming pleats in a graft material of the stent graft by compressing the stent graft, applying heat to the stent graft to thermally set the pleats in the graft material, and extending the stent graft to uncompress the stent graft after the pleats are thermally set.

  • Publication number: 20080084513
    Abstract: A backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide formed from a plurality of segments. Each segment has a first side and a second side opposite the first side, and a first surface extending between the first and second sides and a second surface opposite the first surface. The first surface substantially re-directs light and the second surface substantially transmits light. The plurality of segments are arranged substantially in parallel with the second surfaces transmitting light in substantially the same direction to provide backlighting for a stereoscopic 3D liquid crystal display. A light source is disposed along only one of the first side or second side of each segment for transmitting light into the light guide from either the first side or second side. Each segment light source is selectively turned on and off in a particular pattern.
