Delivery device for use with an embolic coil device and methods for making and using the same

An embolic coil delivery assembly, comprising:

• a tubular member having a distal portion, a proximal portion and a lumen extending therein;
• a tip member secured to the tubular member, the tip member including a distal portion and a bonding portion, the bonding portion including an outer bonding surface and an inner surface, wherein the bonding portion includes a coil, wherein the coil includes a plurality of windings;
• and
• an embolic coil releasably disposed within the distal portion of the tip member;
• wherein the distal portion of the tubular member extends over the outer bonding surface of the tip member;
• wherein the tubular member further comprises an inner surface, wherein the inner surface includes an inwardly extending member, wherein the inwardly extending member extends into a slot between two of the plurality of windings to mechanically interlock with the two of the plurality of windings, and wherein the slot extends through the outer bonding surface and the inner surface of the ponding portion;
• wherein the distal portion of the tip member further includes an aperture directed radially away from a longitudinal axis of the tip member.
