Patent 8668728 was granted and assigned to Boston Scientific on March, 2014 by the United States Patent and Trademark Office.
The invention relates to a system for dilatation of a body passage and delivery of a stent into the body passage of a patient, and related methods of using such a system. The dilatation and stent delivery system may comprise a dilatation catheter having an expandable member on a distal end, and a stent delivery catheter configured to retain a stent and deliver the stent to a body passage. The stent delivery catheter defines a lumen sized to receive the dilatation catheter and permit movement of the dilatation catheter relative to the stent delivery catheter.
