Abstract

The endoluminal device delivery assembly and method for release and deployment of an endoluminal therapeutic device at a desired location for treatment within the vasculature of a patient utilizes an elongated flexible tubular catheter with a tubular distal tip formed of a yieldable material mounted to the distal end of the catheter for releasably holding the proximal end of the endoluminal device. The endoluminal device can be dislodged from the tubular distal tip by a pusher member or pressurized fluid to expel the endoluminal device through at the desired location for treatment within the vasculature of a patient. A flexible coil can be mounted to the distal end of the elongated pusher member to provide for improved tracking.
