Each section includes a plurality of expandable modules and a plurality of bridging modules. Each expandable module includes a plurality of strut elements that join together at a plurality of apices. Each bridging module includes bridging elements that connect an apex of a first module with an apex of a second module. The plurality of expandable modules or the plurality of bridging modules in the first section are more radially stiff than the plurality of expandable modules or the plurality of bridging modules in the second section such that at least a portion of the first section is configured to be placed in a region of a vein subjected to physiologic compression.

Abstract: An embolic obstruction retrieval device including a self-expandable member having a proximal end portion, a main body portion and a distal end portion. Each of the self-expandable portions consists of a plurality of cell structures formed by intersecting strut members. At least one proximal cell structure in the proximal end portion has one or more struts that have a width and/or thickness greater than the width and/or thickness of the majority of strut members in the main body and distal end portions of the expandable member. Attached to at least one of the proximal-most cell structures in the proximal end portion is a proximally extending flexible wire having sufficient length and flexibility to navigate the tortuous vasculature and access the embolic obstruction. In one implementation, the embolic obstruction retrieval device is delivered to the embolic obstruction through the lumen of a delivery catheter.

Abstract: A clot retrieval device including a self-expandable member having a proximal end portion and a main body portion. The self-expandable member is expandable from a first delivery position to a second placement position. In the first delivery position the expandable member has a first overall diameter In one implementation the cell structures that form the self-expandable member have dimensional and material characteristics that result in about a ?1.0N to about a ?1.7N overall reduction in radial force along the length of the expandable member per millimeter of expansion during about an initial 0.50 mm diametric range of expansion from the first overall diameter and that results in about a ?0.10N to about a ?0.35N overall reduction in radial force along the length of the expandable member per millimeter of expansion during subsequent diametric ranges of expansion.

Abstract: A device including a self-expandable member having a proximal end portion and a main body portion. The self-expandable member is movable from a first delivery position to a second placement position, in the first delivery position the expandable member being in an unexpanded position and having a nominal first diameter and in the second position the expandable member being in a radially expanded position and having a second nominal diameter greater than the first nominal diameter for deployment within a vessel or duct of a patient. The expandable member includes a plurality of cell structures with the cell structures in the main body portion extending circumferentially around a longitudinal axis of the expandable member and the cell structures in the proximal end portion extending less than circumferentially around the longitudinal axis of the expandable member. In one implementation the cell structures have dimensional and material characteristics that result in about a ?1.5N to a about a ?3.
