Abstract
Official abstract text for this publication.
A method and apparatus for delivering energy during a surgical procedure such as phacoemulsification is provided. The method and apparatus include delivering energy during a 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for delivering ultrasonic energy during a surgical procedure performed within a surgical environment comprising a fluid, comprising: applying ultrasonic energy at a first energy level above a de minimis energy level for a time period sufficient to induce transient cavitation within the fluid, wherein the time period is between two and three milliseconds; and providing ultrasonic energy for a predetermined period after attaining transient cavitati…
