Abstract:
1. A method of manufacturing a medical device comprising: forming a stent having a proximal end, a distal end, and a longitudinal axis extending therebetween, the stent having a generally cylindrical shape defining a first stent diameter; inserting an expansion member into the stent, the expansion member having a length extending along the longitudinal axis of the stent with at least one slot extending along at least a portion of the length of the expansion member to define a plurality of expansion blades, the expansion member having a first expansion diameter; inserting a mandrel into the expansion member, the mandrel extending along the longitudinal axis, the mandrel having a diameter that is greater than the first expansion diameter and greater than the first stent diameter; wherein the insertion of the mandrel into the expansion member radially expands the expansion member to a second expansion diameter, the radial force exerted by the radial expansion of the expansion member on the stent expands the stent to the second stent diameter, the second stent diameter being greater than the first stent diameter.
