    Abstract: Delivery systems are disclosed for bioresorbable scaffolds that decrease in length when expanded to a deployment diameter that allow accurate positioning of the scaffold at a lesion. The scaffolds are mounted on a catheter that includes marker bands that are positioned interior to the proximal and distal edges of the crimped scaffold to anticipate the shortening of the scaffold upon deployment. Delivery systems are further disclosed for bioresorbable scaffolds that increase in length when expanded to a deployment diameter that allow accurate positioning of the scaffold at a lesion. The scaffolds are mounted on a catheter that includes marker bands that are positioned exterior to the proximal and distal edges of the crimped scaffold to anticipate the lengthening of the scaffold upon deployment.

    Abstract: A system for delivering a stent from a catheter sheath in a longitudinal direction comprising: a thumbwheel mounted on an axle, the axle being supported by opposite walls of a housing; a first pinion mounted on the axle; a second pinion mounted on the axle, whereby rotation of the thumbwheel causes rotation of the first pinion and rotation of the second pinion; a first rack, enageable with the first pinion at a first surface of the first pinion, the first rack being operably connected with a stent-engaging member; a second rack, engageable with the second pinion at a second surface of the second pinion, the second surface being disposed in a direction diametrically opposite the first surface, the second rack being operably connected with a sheath configured to confine the stent.

    Abstract: Multi-lumen catheter having a monolithic elongate tubular shaft member having a proximal end, a distal end and a longitudinal length therebetween. The tubular shaft member has an outer cross-sectional dimension that varies along the length of the tubular shaft member. The tubular shaft member has an inner core made of a first material and an outer layer made of a second material. The inner core has a first lumen and a second lumen defined therein, the first lumen having a first lumen cross-section and a length extending at least along a portion of the length of the tubular shaft member. The first lumen cross-section is substantially uniform along the length of the first lumen. The second lumen has a second lumen cross-section and a length extending along the length of tubular shaft member. The second lumen cross-section is substantially uniform along the length of the second lumen.
