Abstract

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.
