摘要： The present invention generally relates to a medical device and procedure for accurately positioning a catheter across a desired region within a patient's vasculature. In particular, the present invention provides a hub assembly unit that allows a physician to precisely position a stent within a vessel utilizing a stent delivery catheter. The hub assembly unit includes a fine adjustment mechanism. The fine adjustment mechanism extends or contracts the length of the hub assembly unit in controlled incremental units. These controlled fine displacements are then translated directly to the stent delivery or balloon dilation catheter.
