  • Patent number: 7332689
    Abstract: An apparatus for tacking a multi-lumen tubular assembly together comprises a laser, an optical member and a placement tray for retaining the tubular assembly. A portion of the optical member defines a window that is substantially transparent to laser energy emitted from the laser. The window has a substantially concave shaped surface. The placement tray and the window surface define a processing area for positioning at least a portion of the tubular assembly. The processing area receives the laser energy that is emitted from the laser and passed through the window of the optical member. The tubular assembly is defined by an outer tubular member disposed about at least a portion of at least one inner tubular member. The laser energy transmitted into the processing area is transmitted substantially through the outer tubular member and is substantially absorbed by at least one region of the least one inner tubular member.

  • Patent number: 6769161
    Abstract: A stent crimper comprising a plurality of crimping members extending between a first support and a second support. The first and optionally the second supports has an opening therethrough sized to allow a stent therethrough. The first and second supports extend from a base. The crimping members are disposed about the circumference of a circle everywhere along the length of the members. Finally, the flexible members extend through a bore in a die. The die is movable in an axial direction along the flexible members.

  • Patent number: 6352547
    Abstract: A stent crimper is formed of at least one crimping member disposed in a reducible diameter loop. The crimping member includes at least one pulling member extending from the loop. The diameter of the loop is reduced by pulling on the pulling member. A stent placed in the loop may be crimped by reducing the diameter of the loop.
