Abstract
An occluder catheter having an outer tube, an inner shaft extending slidably through the outer tube, and two expanders attached, respectively, to the distal ends of the inner shaft and the outer tube. The expanders each have a plurality of circumferentially spaced, longitudinally oriented fingers. The fingers each have radially expandable ends and radially constrained ends and the fingers of each expander are interposed with the fingers of the other expander. A flexible non-porous sleeve covers at least the fingers of both expanders. By moving the outer tube with respect to the inner shaft, the occluder is transformable between a collapsed configuration and an expanded configuration wherein the fingers of at least one of the expanders are radially splayed to dilate the sleeve. One embodiment of the invention incorporates a single expander having circumferentially juxtaposed fingers, the expander being mated with a deflector ring.
