SYSTEM AND METHOD FOR PREVENTING GAS LEAKAGE FROM AN INTRA-AORTIC BALLOON

A system for limiting inflation of an expandable member (e.g., a balloon) in an intravascular circulatory support system of a patient may comprise a drive unit and an air mover limiter. The drive unit may include an air mover and a motor. The air mover may have a first end and a second end. The firs...

Zusammenfassung:A system for limiting inflation of an expandable member (e.g., a balloon) in an intravascular circulatory support system of a patient may comprise a drive unit and an air mover limiter. The drive unit may include an air mover and a motor. The air mover may have a first end and a second end. The first end may be fixed and have a pneumatic output in fluid connection with the expandable member. The second end may be movable and pneumatically closed. The air mover limiter may be configured to restrict displacement of the second end to under-inflate the expandable member based on the blood pressure of the patient. Displacement of the second end moves a volume of air into or out of the expandable member. The volume of air corresponds to the air mover limiter configuration.
