Abstract: A vascular occlusion system may include a microcatheter configured to navigate a vasculature, an elongate shaft slidably disposed within a lumen of the microcatheter, the elongate shaft having a lumen extending from a proximal end of the elongate shaft to a distal end of the elongate shaft, a plurality of occlusive medical devices releasably connected to the elongate shaft, and a release wire slidably disposed within the elongate shaft and at least a portion of each of the plurality of occlusive medical devices. The release wire secures each of the plurality of occlusive medical devices to the distal end of the elongate shaft when the release wire is disposed within at least a portion of each of the plurality of occlusive medical devices.

Abstract: Embolic material delivery devices and methods of using them are disclosed. An example embolic material delivery assembly includes an outer member having a lumen extending therein and a distal end region, an inner member disposed within the lumen of the outer member, wherein the inner member includes a first lumen extending therein. The embolic material delivery assembly also includes a first embolic material extending within the first lumen of the inner member, the embolic material having a first distal end region. The embolic material delivery assembly also includes an anchor disposed within the lumen of the outer member, the anchor having a first attachment region. Further, the first distal end region of the first embolic material is coupled to the first attachment region of the anchor.

Abstract: The present disclosure relates to the field of delivery systems for precise navigation within and through body passages. Specifically, the present disclosure relates to delivery systems for accurate positioning and release of elements within tortuous, narrow and/or fragile passages. In particular, the present disclosure relates to a delivery system that includes a distal coil with sufficient flexibility to navigate through tortuous body passages, and which allows for controlled stretch when bent.
