摘要： A vaso-occlusive device delivery assembly includes a pusher assembly having proximal and distal ends, a conductive sacrificial link disposed at the distal end of the pusher assembly, and a vaso-occlusive device secured to the pusher assembly by the sacrificial link. The pusher assembly includes first and second conductors extending between the proximal and distal ends thereof. The sacrificial link is electrically coupled between the first and second conductors, such that the first conductor, sacrificial link and second conductor form an electrical circuit, and, when a disintegration current is applied through the sacrificial link through the first and second conductors, the sacrificial link thermally disintegrates, thereby releasing the attachment member and vaso-occlusive device from the pusher assembly.

摘要： A vaso-occlusive device delivery assembly includes a pusher assembly and a vaso-occlusive device detachably coupled to the pusher assembly by an attachment member is frictionally secured within a lumen of the pusher assembly. A heat generating member is disposed in the pusher assembly lumen, along with a pressure generating material, such that, when heat is generated by the heat generative device, the pressure generating material increases a pressure in the pusher assembly lumen, thereby dislodging the attachment member from the pusher assembly and detaching the vaso-occlusive device from the pusher assembly.

摘要： A vaso-occlusive treatment system includes a delivery assembly; and a vaso-occlusive device detachably coupled to the delivery assembly by a delivery assembly junction. The vaso-occlusive device includes a braided portion formed out of one or more composite wires, a coiled portion coupled to the braided portion, and an intra-device junction coupling the braided portion to the coiled portion. Each composite wire includes a core made from a core metallic material, and an external layer made from an external metallic material different from the core metallic material. One of the core and the external layer has a greater radiopacity and a lesser stiffness, respectively, than the other one of the core and the external layer.
