SYSTEM AND METHOD FOR PULSED ULTRASONIC POWER DELIVERY EMPLOYING CAVITATIONAL EFFECT

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for delivering energy during a surgical procedure such as phacoemulsification.

SOLUTION: The method and apparatus include delivering energy during the surgical procedure, including applying energy at a level and for a time period sufficient to induce transient cavitation, and reducing applied energy after applying energy during a second nonzero lower energy period. It is useful that the method and apparatus use beneficial points related to cavitation, and present a system for minimizing defects related to conventional tissue abscision systems.
