Abstract: An adaptive guide bushing for laser workpiece cutting systems, the adaptive guide bushing including an clastic member that expands and contracts to hold a workpiece within a central opening for laser cutting.

Abstract: A stent configured for implantation in a body lumen, includes: a tubular structure having a first end, a second end opposite from the first end, and a tubular body extending between the first and second ends, the tubular body comprising a plurality of elongate portions defining a porosity for the stent, at least one of the elongate portions having a zig-zag configuration, the first end of the tubular structure having a plurality of crown elements disposed circumferentially with respect to a longitudinal axis of the tubular structure, the crown elements forming a crown configuration for the first end of the tubular body; and a plurality of tabs coupled to the first end of the tubular structure; wherein a number of the crown elements is higher than a number of the tabs; wherein the tabs are coupled to only a subset, and not all, of the crown elements.
