Abstract:
1. A vaso-occlusion system for occluding an aneurysm, the system comprising: a delivery catheter extending from a proximal end to a distal end; and a vaso-occlusive device within the delivery catheter, wherein the vaso-occlusive device is adapted to be pushed out of, and retrieved back into, the distal end of the delivery catheter, the vaso-occlusive device comprising: an elongate inner member having a diameter; a soft outer braided tubular member formed of about 24 to 36 strands comprising a Nitinol wire having a thickness that is 0.0010 inches or less in diameter, wherein the braided tubular member is attached and fixed to the inner member at a proximal end of the braided tubular member and extends in a longitudinal axis over the inner member but is not attached to the inner member at a distal end of the braided tubular member, further wherein the braided tubular member has a length that is greater than 5 cm, forms a braid angle between crossing strands in a direction of the longitudinal axis of about 35 degrees or less when held within the delivery catheter, and expands relative to the inner member to a diameter of greater than 1.5 times the diameter of the inner member when released from the delivery catheter.
