Abstract
A controlled volume inflation-deflation device to inflate a balloon to occlude a blood vessel by dialing a knob that locks at rotational positions to locate a plunger at equally spaced locations within a syringe of the inflation-deflation device. The inflation-deflation device includes a releasable latch to lock the proximal and distal housings together to hold the plunger forward for occlusion, and to separate and hold the proximal and distal housings to retract the plunger for perfusion. When the inflation-deflation device is returned to the latched position, the balloon is re-inflated to its previous occlusive diameter. Also, an extension tube made of a lower modulus outer material co-extruded over and miscible with a higher modulus inner material may be used. The balloon may have tapered ends and a cylindrical center portion so that it increases by more equal increments in outer diameter to incremental equal increases in inflation volume.
