Endovascular Retrieval Devices are used in intravascular foreign body retrieval (e.g., embolic coils) procedures. The Alligator Retrieval Device (ARD) is a dedicated microforceps which allows intravascular access and retrieval of the foreign body. It consists of 4 small microprecision grasping arms mounted on a flexible microguidewire and is used with a standard 0.21 mm microcatheter. Once the system is advanced adjacent to the foreign body, the microguidewire is held in place and its atraumatic gripping arms are deployed by withdrawing the microcatheter. The Alligator Retrieval Device has been specifically designed and indicated for use in the peripheral and neurovasculature for foreign body retrieval.
