ABSTRACT:
A stent positioning apparatus and method are provided for the attachment of a stent to a balloon to be used in the treatment of stenosis, such as coronary angioplasty. In one preferred embodiment, a first generally cylindrical member has a radially deformable wall defining a channel within which the stent and balloon assembly are inserted. A second generally cylindrical member has an opening sufficient to receive the first member with the assembly therein. The second member is then slid longitudinally over the deformable wall of the first member causing nonuniform depressions to be formed in the inner diameter of the stent, thus crimping the stent onto the balloon. Thus, the stent is attached to the balloon without damage and without risk of the stent falling off the balloon prematurely.
