Procedure Overview


MicroVention advances endovascular coil embolization technology to a new level of simplicity and performance.

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 is then purged of air using a sterile saline-filled 1-cc syringe.

The device is inserted into the microcatheter hub. The protective introducer sheath is retracted. The device is then advanced through the microcatheter.

The end of the device (coil) is advanced carefully out the end of the microcatheter into the aneurysm under fluoroscopic guidance.

When properly positioned, a 1/4-cc syringe filled with contrast agent is attached to the microcatheter hub. The coil is detached from the pusher assembly by injection of contrast.

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.
