ABSTRACT:
A vasoocclusive member, such as embolic coil, that mechanically joins an instrument for delivering that vasoocclusive member to a selected site within the vasculature or other lumen of a human body via the use of a catheter is provided. A thermoplastic member augments the junction to enhance variously the friction at an integrity of the junction. Once the vasoocclusive member is delivered to the desired site, radio frequency energy is supplied to the thermoplastic member in an amount sufficient to soften the thermoplastic member, allowing mechanical disengagement to then take place.
