Description

ABSTRACT:
This invention is a surgical instrument and specifically is a device for delivering an embolic coil to a selected site within the vasculature of a human body via use of a catheter. In particular, the device uses embolic coils having interlocking clasps on the coils which are secured to each other by a control wire within the catheter. Retraction of the control wire into the catheter body uncouples the distal coil.
