Abstract
An insertion device for an intraluminal graft is provided, including a deployment catheter which has a deployment shaft and an expanding frame with an umbrella-like assembly. The assembly is suitable for radially expanding a graft. The device also includes a deployment grip connected to the deployment shaft. A coil interposed between the deployment grip and the expanding frame resiliently urges the expanding frame, with the deployment grip reversibly operating the expanding frame thereby. The deployment catheter collapses for removal from the vessel lumen after the intraluminal graft has been introduced therein. This intraluminal graft is deployed through a catheter and expanded in place to anchor the graft to the vessel wall. The expanding frame is then collapsed and withdrawn from the lumen. The insertion device also can be configured as an intraluminal dilation device that can be used to dilate a lumen and to ensnare an intraluminal object.
