Abstract
A delivery system for an implantable vaso-occluding device. A non-planar heating chamber is disposed proximate to a distal end of an advancing member. Protruding from an interior surface of the non-planar heating chamber is a detachment fiber made from a polymeric material and having a closed distal end. At least one heating element is disposed on the interior surface of the non-planar heating chamber to produce sufficient heat to sever the detachment fiber. An articulation point is established between the vaso-occluding device and the delivery system. The vaso-occluding device remains at all times substantially self-centered while being advanced.
