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. ## Claims ### Claim 1 An embolic material delivery assembly, comprising: 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 two or more lumens extending therein; two or more embolic materials extending within the two or more lumens of the inner member, the two or more embolic materials each having a distal end region and a proximal end region; and an anchor disposed within the lumen of the outer member, the anchor having an attachment region; wherein the distal end region of each of the two or more embolic materials is coupled to the attachment region of the anchor when the anchor is disposed within the lumen of the outer member. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the anchor is positioned distal to a distal end of the inner member. ### Claim 3 (depends on 1) The assembly of claim 1, wherein the anchor includes a coiled wire. ### Claim 4 (depends on 3) The assembly of claim 3, wherein coupling each of the two or more embolic materials to the attachment region of the anchor includes engaging the distal end region of each of the two or more embolic materials with at least one winding of the coiled wire. ### Claim 5 (depends on 4) The assembly of claim 4, wherein each of the two or more embolic materials defines a length extending between the distal end region and the proximal end region, and wherein the proximal end region of each of the two or more embolic materials is disposed within the inner member prior to deployment. ### Claim 6 (depends on 4) The assembly of claim 4, wherein the proximal end region of each of the two or more embolic materials extends proximally from the inner member catheter prior to deployment. ### Claim 7 (depends on 3) The assembly of claim 3, wherein the inner member is configured to translate along a longitudinal axis of the outer member, and wherein translation of the inner member pushes the coiled wire out of a distal end of the outer member. ### Claim 8 (depends on 1) The assembly of claim 1, wherein the anchor includes an elongated shaft member having a first arcuate portion and a second arcuate portion. ### Claim 9 (depends on 8) The assembly of claim 8, wherein the attachment region includes an aperture, and wherein coupling each of the two or more embolic materials to the attachment region of the anchor includes engaging the aperture. ### Claim 10 An embolic material delivery assembly, comprising: an embolic coil having a proximal end and being disposed within a delivery catheter; an inner catheter including two or more lumens extending therein, the inner catheter being slideably disposed within an outer catheter and being proximal of the embolic coil; two or more embolic materials, each of the two or more embolic materials extending within a separate lumen of the two or more lumens of the inner catheter and having a distal end region; and wherein the outer catheter includes an aperture having a cutting edge and extending through a distal side wall of the outer catheter, and a distal end of the inner catheter is located proximal of the aperture in a first configuration, wherein the distal end region of each of the two or more embolic materials is coupled to the proximal end of the embolic coil at a point distal of the outer catheter, wherein in a second configuration the distal end of the inner catheter is located distal of the aperture through the distal side wall of the outer catheter and each of the two or more embolic materials has been severed by the cutting edge. ### Claim 11 (depends on 10) The assembly of claim 10, wherein the embolic coil is positioned distal of the outer catheter. ### Claim 12 (depends on 11) The assembly of claim 11, wherein the outer catheter is sized and configured to translate within a lumen of the delivery catheter, and wherein distal translation of the outer catheter pushes the embolic coil out of a distal end of the delivery catheter.
