Patent ID: 7527605

Claim:
A medical-balloon inflator comprising: a) a medical-balloon-inflator housing having a pump outlet operatively connectable to a medical balloon; b) a pump piston assembly disposed in the housing and operatively connected to the pump outlet; c) a movable pivot; d) an actuator handle having first and second detents, and also including a fulcrum bar having a first end defining a movable pivot wherein the first end of the fulcrum bar is disposed in the first detent in the first pivot location, and wherein the first end of the fulcrum bar is disposed in the second detent in the second pivot location; the actuator handle being operatively connected to the movable pivot and adapted to translate the pump piston assembly to inflate the medical balloon when the medical balloon is operatively connected to the pump outlet and when the actuator handle is rotated an angular distance about the movable pivot by a user, wherein the movable pivot has spaced-apart first and second pivot locations wherein the actuator handle has a free end, and wherein the distance from the free end to the first pivot location is shorter than the distance from the free end to the second pivot location and wherein the movable pivot is at the first pivot location before the actuator handle is rotated by the user, and wherein the movable pivot is at the second pivot location when the actuator handle is rotated the angular distance about the movable pivot by the user; and e) a return spring operatively connected to the fulcrum bar to return the first end of the fulcrum bar to engage the first detent when the user releases the actuator handle.
