Abstract:
1. An endoluminal expansion system comprising: a) an elongate actuation member having a distal end; b) a substantially tubular sheath mounted coaxially about the elongate actuation member, said substantially tubular sheath having proximal and distal ends and a length extending between those ends, and further having multiple parallel slots extending along less than the entire length of the substantially tubular sheath, said elongate actuation member being axially movable with respect to the substantially tubular sheath, wherein the distal end of the substantially tubular sheath is secured to the distal end of the elongate actuation member; and c) an expandable endoprosthesis affixed coaxially about the substantially tubular sheath; wherein the application of tension to the elongate actuation member applies compression to the substantially tubular sheath whereby a radially outward force is applied to the expandable endoprosthesis by the substantially tubular sheath.
