of the present invention is shown in fig1 and is comprised of inner and outer coaxial members for example a shaft or tube the outer tube which is also known as outer sheath 11 constrains stent 12 in a crimped or radially compressed state the inner members can be comprised of multiple components including distal tip 8 guide wire tube 14 and pusher 16 to react the axial forces placed on the stent as the outer sheath is retracted to deploy the stent pusher 16 can also act as a proximal stop other elements of the stent delivery system can include luer lock hub 6 attached to the proximal end of pusher 16 handle 3 attached to outer sheath 11 that incorporates luer port 4 such that the space between the inner members and outer sheath 11 can be flushed with saline solutions to remove any entrapped air pusher 16 is sometimes a composite structure of multiple components such as a stainless steel tube at the proximal end and a polymer tube inside outer sheath 11 stent delivery system 10 of the present invention shown in the detail view of x x section fig2 is comprised of outer sheath 11 a delivery catheter in which stent 12 is constrained in a crimped or radially compressed state stent delivery system 10 can be referred to as catheter delivery system as a delivery catheter slider 13 is positioned.
