Abstract
A new retrieval device for use in small vessels was evaluated in a canine model. Retrieval was attempted on 25 coils, three silicone balloons, and five catheter and guide wire fragments placed in the renal, pulmonary, hepatic, brachiocephalic, subclavian, carotid, and maxillary arteries. This was successful in 91% (30/33). The snare could also be selectively placed in the vertebral and proximal basilar arteries.
