Abstract
A delivery device adapted to insert and deploy a stent within a body lumen. The delivery device includes a guide member adapted to retain a dilation assembly and a stent within a lumen thereof until the stent is to be deployed into the body lumen. The delivery device is configured to enable simultaneous insertion of the guide member, dilation assembly, stent, and optional guidewire within a body lumen. Following deploying the stent, the delivery device can be removed, while providing the capability of optionally maintaining the guide member or the guidewire to function or act as an exchange wire for additional surgical devices.
