Abstract

The present coaxial traction detachment system improves intravascular occlusion by providing a means for greater control in the placement of endovascular devices. The detachment apparatus (10) includes a guide wire (16) slidably disposed within a sheath (14). An endovascular device (18) is attached to the distal end of the guide wire (16). The sheath (14) is guided through a catheter (12) to a device detachment location. The device (18) is attached to the wire (16) either by a glue or solder or by mechanical means such as the intertwining of the device (18) to the guide wire (16). Following device placement and prior to detachment, the operator is able to observe the position and configuration of the device. If the position is unsatisfactory, he need only withdraw the sheath to remove the device. If placement is satisfactory, the system utilizes a coaxial detachment method such that the operator places traction on the guide wire and the device is pulled against the outer sheath, causing it to detach.
