ABSTRACT:
Ultrasonic devices for preventing microbubbles and/or microparticles from reaching the brain during a PCI or cardiovascular surgery. Devices27and77are designed for implantation in the chest cavity and operate in combination with needle vents or other vent systems for removing diverted microbubbles. Systems77and83are designed for noninvasive employment. Devices57and87are particularly designed to prevent microbubbles from reaching the great origins of the carotid arteries and/or for diverting bubbles that might reach the vicinity and otherwise pass through. Improved devices11and94separate microbubbles from a flowing bloodstream and produce a cleansed stream.
