摘要： A vaso-occlusive coil formed of a wire having a primary configuration in a constrained condition. The coil assumes a secondary configuration in a relaxed, unconstrained condition. The secondary configuration comprises a primary portion comprising a plurality of primary loops, including a distal-most primary loop. A distal anchoring loop is connected to the distal end of the distal-most primary loop. The distal anchoring loop has a substantially triangular shape and is much smaller than the distal-most primary loop. The distal anchoring loop prevents herniation of the device during deployment and retention within an anatomical cavity.

摘要： A vaso-occlusive device comprises a wire having a primary configuration in a constrained condition. The wire forms a secondary configuration in a relaxed, unconstrained condition. The secondary configuration comprises a pyramidal portion comprising a plurality of distal coils. Each distal coil is wound from the wire such that the winding has a perimeter which tapers outwardly from an interior of the pyramidal portion, and a transition segment of the wire between each distal coil and connecting each distal coil. The plurality of distal coils is arranged in a pyramidal shape such that each coil lies in a different lateral face of the pyramidal shape. The vaso-occlusive device may also include a body portion proximal of the pyramidal portion formed from the wire and extending proximally from the pyramidal portion.

摘要： A vaso-occlusive device (10) is formed from an elongate strand of material (16) wound by a winding process into a helical coil having a length, wherein one or more discrete sections (14) of the coil along its length were subjected to less mechanical stress or strain than a remainder (12) of the coil during the winding process, such that each of the one or more discrete sections has a lower stiffness and greater flexibility than a respective stiffness and flexibility of the remainder of the coil, and such that each of the discrete one or more sections acts as a bending location along the length of the coil when the coil is delivered into an aneurysm.

摘要： A vaso-occlusive device delivery assembly includes a pusher assembly (200) having a proximal end, a distal end, and a pusher lumen (212) extending therebetween; a vaso-occlusive device (300); and a tubular member (238) mechanically connecting the pusher assembly to the vaso-occlusive device, the tubular member having a proximal end, a distal end, a tube lumen extending therebetween, and a detach zone (244), wherein the proximal end of the tubular member extends into the pusher assembly lumen at the distal end of the pusher assembly. A heat generating member (210) is disposed in the tube lumen, such that, when activated, the heat generating member generates heat that melts or otherwise thermally degrades the tubular member at the detach zone, thereby detaching the vaso- occlusive device from the pusher assembly.

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.
