Abstract
A retrievable device for treatment of a stenotic lesion in a body vessel is disclosed. The device comprises a reticulation portion including a plurality of struts connected together in a singly staggered configuration distally along a longitudinal axis. The plurality of struts of the reticulation portion is configured to fold along the longitudinal axis defining a collapsed state of the device for retrieval. The device further includes an expandable body distally extending from the reticulation portion along an outer diameter for treatment of the stenotic lesion. The expandable body is configured to expand in the open state and collapsed in the collapsed state of the reticulation portion for retrieval. The device further comprises a retrieval stem extending proximally from the reticulation portion for retrieval of the device in the collapsed state.
