Abstract
A delivery device for delivering an implantable, radially expandable medical device having a constricted region for occluding fluid flow to a desired location in a body lumen. The delivery device includes an outer sleeve, an inner tube terminating at its distal end in a plunger, and a tapered guide member. In one embodiment, the tapered guide member is attached to and extends away from the constricted region of the occlusion device, and is thus implanted in the body lumen along with the occlusion device upon deployment of the occlusion device at the desired treatment location. In a second embodiment, the tapered guide member is integrated into the constricted region of the occlusion device. In a third embodiment, an inflatable balloon is positioned distally of the medical device, and when inflated provides a tapered guide surface that eases the navigation of the delivery device through the body lumen. Upon deployment of the medical device at the desired location, the balloon is deflated to such a size as to be able to be withdrawn through the constricted region of the occlusion device, and is thus removed from the body lumen.
