Abstract:
An intravascular guidewire inflation system, comprising:a hollow metallic body having distal and proximal portions, said body having a central lumen formed therein with distal and proximal ports in fluid communication with said lumen;an expandable member mounted on said distal portion of said body and adapted to be in fluid communication with said distal port of said central lumen, such that fluid introduced through said proximal port will cause actuation of said expandable member;a valve movably inserted with respect to said proximal port of said body, said valve movable between a first position to seal said central lumen to prevent deactuation of said expandable member and a second position to unseal said central lumen to allow actuation or deactuation of said expandable member; anda valve adaptor which may be removably mounted on said proximal portion of said body, said adaptor having an auxiliary lumen adapted to be in fluid communication with said proximal port of said central lumen and further adapted to receive a fluid delivery device for selectively actuating or deactuating said expandable member, said adaptor having a first seal to engage said metallic body at a point distal to said proximal port, and a second seal to engage said valve, such that when said first and second seals are engaged on said distal point and said valve, a fluid tight sealing chamber is established surrounding said proximal port.
