Abstract
An introducer assembly (10) includes a balloon catheter (12) for deploying a medical device (19) in a body lumen or for dilating a body lumen at a range of diameters from a minimum deployment diameter to a maximum deployment diameter. The balloon catheter includes an outer balloon (42) and an inner balloon (40) located within the outer balloon (42). The outer balloon (42) has an unstretched diameter equivalent to the minimum deployment diameter and the inner balloon (40) has an unstretched diameter equivalent to the maximum deployment diameter. The outer balloon (42) is made of an elastic material able to stretch from the minimum deployment diameter to the maximum deployment diameter, while the inner balloon (40) is preferably of an non-compliant material.
