Beschreibung
Zusammenfassung:	This invention is a surgical instrument, and specifically is a device for delivering embolic coils to a selected site within the vasculature of a human body. This instrument uses, and may include, the catheter used to place the embolic coil. In particular, the device is made up of a pusher wire having a distal tip which is configured to engage the proximal end of an embolic coil. The device may also include a cylindrical pusher which coaxially surrounds at least a portion of the pusher wire and cooperates in the disengagement of the coil from the pusher wire and the ejection of the vasoocclusive coil into the selected vascular site. The pusher wire's engagement tip may be of any selected and convenient shape, and may be grooved, if so desired, to enhance the engagement joint strength.
