Abstract
Abstract An introducer system having an elongate shaft with proximal and distal ends. A flexible sleeve is mounted on the distal end of the shaft and is adapted to circumferentially cover the outer surface of a distal end of a cannula when the shaft is positioned within a lumen of the cannula. The introducer system has dilation capabilities which facilitates insertion of a medical device into a vessel or organ. Methods of using the devices herein are also disclosed.
