Using standard interventional techniques, vascular access is obtained typically through a femoral incision. Typically, a microcatheter is placed through a guide catheter and advanced to the embolization site, often with the use of a guidewire. The guidewire is then removed.

Fluoroscopy is used to create a "road map" and measure the size of the aneurysm. The size information is used to select the appropriate coil.

A device is removed from its package and inspected. 

The device introducer sheath is inserted into the microcatheter hub via a Rotating Hemostatic valve attached to a saline flush. The coil and pusher are advanced through the introducer sheath.  Once the pusher has been advanced as far as possible, the introducer sheath is removed and the coil is advanced to the end of the microcatheter.  When the coil exit markers approach the rotating hemostatic valve, the coil is about to exit the microcatheter. The coil is advanced carefully out the end of the microcatheter into the aneurysm under fluoroscopic guidance.

When the coil is properly positioned, The V Grip detachment device is placed on the proximal end of the pusher.  The detach button is depressed and the coil will thermo-mechanically detach in 0.75 seconds.  The detachment handle will emit 3 beeps and the light will flash indicating that the detachment cycle has occurred.

Endovascular treatment of cerebral aneurysms offers numerous advantages over surgery, including less invasive access, reduced hospitalization and recovery time, reduced risk of infection, and substantially reduced overall cost.
