  • Patent number: 5776161
    Abstract: An expandable stent and stent graft having a small initial diameter, flexibility along its longitudinal axis prior to expansion and a large expanded and rigid Local strain on the stent material is minimized, as and after the balloon is expanded. More particularly, the stent has rotation joints having minimal strain during stent expansion. The stent is substantially the same length before and after expansion and being flexible longitudinally when constrained, it is easy to locate. A method of manufacturing stents is described comprising rotation of a tube beneath a moving film, with light passing through the film onto the tube, at selected locations. A laser scanning system for stent manufacture is also disclosed.

  • Patent number: 5372600
    Abstract: This invention is directed to stent delivery systems. In one embodiment an apparatus for implanting a flexible, generally cylindrical, expandable stent, comprises a catheter having distal and proximal ends, the catheter defining a central lumen and a second lumen extending therethrough and having two longitudinally displaced openings extending from the second lumen radially to the surface of the catheter; a flexible, expandable stent having discrete proximal and distal ends, the stent being positioned circumferentially around the catheter and the discrete ends extending into the openings to hold the stent in position; and at least one release wire positioned in and extending through the second lumen, the release wire or wires fixedly containing at least one conically shaped pushing member capable of causing a discrete end of the stent to move radially as the release wire is moved proximally.

  • Patent number: 5246445
    Abstract: This invention is directed to a system for implanting a device to open constrictions in corpeal conduits, which comprises (a) an elongated tubular member and (b) a spatial spiral of elongate axial extension wound of thin wire and having attachment means at each end, said spiral being positioned on and concentric to said elongated tubular member, said spiral being in a constricted condition such that its lateral profile is smaller than it would be if said spiral were not constricted.
