摘要：
A device including a self-expandable member having a proximal end portion and a main body portion. Each of the self-expandable portions consists of a plurality of cell structures formed by intersecting strut members. In one implementation, 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 of the expandable member. In another implementation at least some of the intersecting strut members have a thickness to width ratio of greater than one. 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 of a patient. In another implementation, the device is delivered to the treatment site through the lumen of a delivery catheter.
