Abstract: An embolic coil with improved anchor, system, and method of manufacture, formed from shape memory wire comprises primary, secondary, and tertiary coils. Secondary coils may be formed from one or more open, single-turn, multi-turn, or transition loops. Anchor groups at distal and/or proximal portions of the coil may comprise one or more open, single-turn, or multi-turn loops, and may be used to facilitate manufacturing to improve safe anchoring of the coil within an aneurysm sac, regardless of the neck size. The coil may be formed on a mandrel with a groove in one or more spherical and cylindrical surfaces, which may be scaled to fabricate a variety of coil sizes. The multiple coils of the anchor and intermediate portions deploy self-adaptively in separate, non-parallel planes, substantially assuming the inner surface of an irregularly shaped, constricted, or un-constricted, aneurysm and provides improved framing, filling, and uniform fill distribution.

Abstract: The present invention relates to a spring to return more quickly the jaws of a gripper assembly of a delivery system for deploying an embolic coil. Each of the jaws and spring are formed of shape memory alloy configured to be movable between a first position and a second position and returning to the first position, with the spring tension increasing the speed of the return to the first position of the jaws of the gripper assembly. The gripper assembly may be used to insert, retract, reconnect, and rapidly disconnect from the embolic coil.

Abstract: A vaso-occlusive device, delivery system and method of delivery to a selected site of the vessel in a manner allowing the vaso-occlusive device to substantially assumes a diameter of an inner surface of the vessel or aneurism sac at the site of the embolization procedure. The vaso-occlusive device or embolic coil has specific properties of wanting to float and conform to the diameter of the aneurysm sac thereby enabling retractability and rapid disconnect detachment for such embolic coil, and a predetermined shape requiring fewer embolic coils per embolization procedure advantageously improving patient risk, and the cost and time of the procedure. A method for deploying the embolic coil with such specific properties to the site of an aneurysm using a delivery system configured for deploying the embolic coil features inserting, and/or reconnecting for positioning and reinserting the embolic coil.

Abstract: An embolic coil configured with a self-adaptive floating diameter in a relaxed condition substantially assuming the shape of the inner surface of the vessel at the site of an embolization procedure. The embolic coil comprises a distal end having an anchoring loop for anchoring at the site, a proximal end with a loop for detaching from a gripper assembly adapted to deliver to the site, a primary framing coil formed of a plurality of primary omega curves extending between the proximate and distal ends, and a secondary filling coil arrangement formed from a plurality of secondary omega curves that follow the trajectory of the plurality of primary omega curves along the longitudinal length of the embolic coil between the proximate and distal ends. The embolic coil conforms to the diameter of the aneurysm sac enabling retractability and rapid disconnect detachment for such embolic coil advantageously requiring fewer embolic coils.
