Abstract:
1. An expandable inflation device for up to two balloon catheters for angioplasty, said two balloon catheters including a first catheter and a second catheter, said inflation device comprising: a pump mechanism having a tubular reservoir with an outlet and a longitudinal axis, and piston movable linearly through the tubular reservoir along the longitudinal axis, and a manually operated actuator coupled to said piston and controlling linear motion of the piston; and a primary three-port valve having a first primary port in fluid communication with the outlet of the pump, a second primary port and a third primary port, said primary three port valve being switchable between a first state in which the first primary port, second primary port and third primary port are in fluid communication, and a second state in which the first primary port and second primary port are in fluid communication, and a third state in which the first primary port and third primary port are in fluid communication, and a fourth state in which the second primary port and third primary port are in fluid communication; and a first pressure measuring device in fluid communication with the second primary port of the primary three-port valve; and a second pressure measuring device in fluid communication with and releasably attachable to the third primary port of the primary three-port valve; and a first outlet port in fluid communication with the first pressure measuring device and the second primary port of the primary three-port valve, said first outlet port being attachable to the first catheter; and a second outlet port in fluid communication with the second pressure measuring device and the third primary port of the primary three-port valve, said second outlet port being attachable to the second catheter.
