Abstract
A balloon catheter including a pumping mechanism for inflating the balloon, an actuator and control wire for deflecting a distal tip of the catheter and a luer connection for passing a guidewire through the catheter. The balloon can be inflated with a push button which can be locked when depressed so as to inflate the balloon. The balloon is deflated by rotating the push button so that a return spring expands an air bladder and returns the push button to a non-inflating position. The control wire is manipulated by a pivotal lever or a slidable ring. The ring can include a projection which extends through a slot in the housing or the ring can include a circumferentially extending surface which can be finger actuated at any position around the catheter tube.
