Abstract: A system for internal iliac preservation includes a catheter having a distal catheter portion and a proximal catheter portion; a first guidewire having a proximal portion extending from the proximal catheter portion, a distal portion and a medial portion disposed between the proximal portion and the distal portion; a first outer sheath slidably disposed over distal catheter portion; and an integrated second delivery system disposed within the outer sheath at the distal catheter portion. The integrated second delivery system includes a second guidewire; an expandable stent-graft disposed over a lumen of the second guidewire, and a slidable connector slidably disposed over the medial portion of the first guidewire, where the second guidewire is slidably engaged with the slidable connection to permit movement of the integrated second delivery system along the first guidewire when the first outer sheath is retracted from distal catheter portion.

Abstract: An optical light diffuser providing a generally cylindrical pattern of light emission. The diffuser is formed from an optical fiber operable to transmit the optical radiation from its proximal end to its distal end and having a guiding core and a cladding surrounding the core. The optical fiber has an abraded section at its distal end that allows light to escape uniformly over the abraded section forming a generally cylindrical pattern of diffuse light that surrounds the distal end of the optical fiber.
