摘要:
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.
