The present invention advantageously provides alternative systems and methods for severing implantable occlusive devices, particularly hydratable polymeric filaments, from delivery catheters during and/or subsequent to intraluminal delivery, advancement, and/or positioning of occluding filaments into treatment sites. One method for severing an occlusive element from an intraluminal delivery catheter comprises positioning a delivery catheter in a body lumen and advancing at least one occlusive element to a target site. Energy is then transmitted to a severing element so as to break the occlusive element at a selected location along a length thereof for its release to the target site. |
