Zusammenfassung:A vaso-occlusive device comprising an elongate main portion (such as a braided portion) having a plurality of openings along a length of the main portion (such as the openings between the strands of a braid). The main portion has a first bending stiffness. An atraumatic distal segment coupled to, and extending distally from, the distal end of the braided portion. The distal segment has a second bending stiffness. The ratio of the second bending stiffness to the first bending stiffness is within a specified range, which alleviates the problem of the distal segment entering and engaging the openings of the main portion while maintaining deployment performance of the device.
