A vascular graft incorporating a stent into a portion of its length. While various materials may be used for the vascular graft, the graft is preferably an ePTFE graft. The stent is preferably a self-expanding stent, although it may alternatively be a balloon expandable stent. The vascular graft preferably has a continuous inner tubular liner that extends between the opposing ends of the graft and provides a continuous luminal surface for blood contact that is uninterrupted by seams or joints. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent.

A system and method for assembling a plurality of components into an assembly is provided. The system includes an assembling robot and an adhesive dispensing robot. The assembling robot is configured to attach a first sub-assembly to a second sub-assembly. The first sub-assembly includes at least one of the plurality of components, and the second sub-assembly includes remaining ones of the plurality of components. The adhesive dispensing robot is configured to apply an adhesive between the first sub-assembly and the second sub-assembly, after the first sub-assembly is attached to the second sub-assembly, to bond the first sub-assembly to the second sub-assembly.

A system for assembling a plurality of components into an assembly is provided. The system includes an installation table, a first transfer robot, a second transfer robot, and an adhesive dispensing robot. The first transfer robot is configured to assemble some of the plurality of components into a first sub-assembly and transfer the first sub-assembly to the installation table. The second transfer robot is configured to assemble remaining ones of the plurality of components into a second sub-assembly, transfer the second sub-assembly to the installation table, and attach the second sub-assembly to the first sub-assembly. The adhesive dispensing robot is configured to apply an adhesive between the first sub-assembly and the second sub-assembly, after the second sub-assembly is attached to the first sub-assembly, to bond the second sub-assembly to the first sub-assembly.

Described embodiments are directed toward prosthetic valves having leaflets that move asymmetrically in that a leaflet second side region of the leaflet initially moves toward the open position before a leaflet first side region and the leaflet first side region initially moves toward the closed position before the leaflet second side region. In the fully open position, the leaflet first side region opens less than the leaflet second side region. Asymmetric opening and final open position, in synchrony with the other leaflets having the same motion and final open position creates spiral flow exiting the open valve that increases blood flow on the downstream side of the leaflet and thus reduces stagnation of the blood that might lead to thrombus formation. Controlled asymmetric movement of the leaflet reduces closing volume by initiating closure on the leaflet first side region and finishing closures on the leaflet second side region.

When plate-shaped components are inserted in the correct order and orientation into component insertion grooves of a component assembly jig, the component insertion grooves are blocked by the plate-shaped components, and the blowing of compressed air is stopped. When the blowing of compressed air from the component insertion grooves is stopped, the pressure in a compressed-air path increases, and an alignment-complete lamp is illuminated. Using the component assembly jig enables an assembly operation for overlapping the plurality of plate-shaped components in the correct order and orientation, without excess or deficiency, to be efficiently performed without error.
