A DELIVERY APPARATUS FOR A SELF-EXPANDING STENT |
摘要 |
In accordance with the present invention, there is provided a delivery apparatus for a self-expanding stent. The apparatus has an outer sheath forming an elongated tubular member having distal and proximal ends and an inside and outside diameter. The apparatus also includes an inner shaft located coaxially withi n the outer sheath. The inner shaft has a distal end, a proximal end and a longitudinal axis extending therebetween. At least a portion of the inner shaft is made from a flexible coiled member. The shaft preferably includes a stop attached thereto, the st op being proximal to the distal end of the sheath. Lastly, the apparatus includes a self--expanding stent located within the outer sheath, wherein the stent makes frictional contact with the outer sheath and the shaft is disposed coaxially within a lumen of the stent. During deployment of the stent, the stent makes contact with the stop .
