Abstract

A method of and system for mounting a vascular occlusion balloon on a delivery catheter. The occlusion balloon has an interior and a neck having access to the interior and a self-sealing internal balloon valve positioned at least partially in the neck. The mounting system includes a stylet having a distal end that is insertable through the longitudinal passageway of a peel-away sheath and through the internal balloon valve and into the interior of the occlusion balloon. When the stylet is inserted in the occlusion balloon, the peel-away sheath is advanced through the valve into the interior of the balloon. The stylet is removed from the balloon and peel-away sheath, and a soft durometer, flexible tip delivery catheter inserted into the interior of the balloon through the peel-away sheath. The sheath is peeled away from the delivery catheter and out of the internal balloon valve and the interior of the balloon. The mounted balloon is introduced into the vascular system through an introducer catheter and flow directed from the introducer catheter to an occlusion site. When positioned at the occlusion site, the delivery catheter inflates the occlusion balloon for lodgement in the vessel. The delivery catheter is pulled for detachment from the lodged occlusion balloon.
