Delivery device for use with an embolic material

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.
