摘要：A surgical device combines an occlusion balloon to block antegrade flow ofblood in the internal carotid artery during an angioplasty procedure with an exchangeguidewire to facilitate the insertion of devices for performing the angioplasty procedure.The occlusion balloon/guidewire device comprises a microcatheter with a soft platinumguidewire extending therein. A silicone occlusion balloon is attached to the distal end ofthe microcatheter. A self-sealing valve at the distal end of the balloon permits theguidewire to extend distally therefrom. A Tuohy-Borst adapter is attached to theproximal end of the microcatheter to permit inflation of the occlusion balloon. Aguidewire extension is inserted through the Tuohy-Borst adapter to seal themicrocatheter once the balloon has been inflated. The Tuohy-Borst adapter is thenremoved over the guidewire extension member allowing the microcatheter to be utilizedas an exchange guidewire.
