    摘要： A stent delivery assembly comprises a balloon catheter with a rotatable assembly disposed thereabout. The rotatable assembly comprises a rotatable sheath which in a reduced state is freely rotatable about the medical balloon and when in the expanded state is frictionally engaged by the expanded balloon. A secondary guide wire housing is at least partially engaged to the rotatable sheath. A stent may be disposed about at least a portion of the rotatable sheath and at least a portion of the secondary guide wire housing so that a distal end portion of the secondary guide wire housing exits the flow path of the stent through one of the plurality of cell openings which the stent defines.

    摘要： A stent delivery system which has a catheter including an inflatable portion. A stent being disposed about the inflatable portion of the catheter, the stent having a contracted state and an expanded state. A pair of stent retaining sleeves which are partially composed of PTFE, each sleeve having a first end portion overlying a respective end of the stent, each sleeve having a second end portion respectively attached to the catheter, the sleeves retaining the stent to the catheter when the stent is in the contracted state, the stent being freed from the sleeves when the stent is placed in the expanded state. The sleeves being placed on the stent by heat shrinking. The inflatable portion of the balloon optionally having stepped compliant characteristics.

    摘要： The present invention relates to a stent delivery system in which a catheter carries on its distal end portion a stent which is held in place around the catheter prior to and during percutaneous delivery by means of one, and preferably two, end sleeves. The sleeves are positioned around the catheter with one end portion of each sleeve associated thereto. The other end of each sleeve overlaps an end portion of the stent to hold it in place on the catheter in a contracted condition. The present invention provides an improvement with respect to lubrication of the sleeve prior to its assembly with the catheter. A preferred way of lubricating the sleeve is by incorporating a lubricant additive within the sleeve composition.
