Enhanced microburst ultrasonic power delivery system and method
First Claim
1. A method for delivering energy during a surgical procedure, comprising:
- applying ultrasonic energy during at least one pulsed energy on period, wherein applying energy during the pulsed energy on period comprises;
applying ultrasonic energy during a series of short burst periods, said short burst periods interspersed by short rest periods wherein minimal energy is applied; and
refraining from delivering ultrasonic energy during a long off period, the long off period comprising a relatively long period when minimal energy is applied, wherein one long off period follows each pulsed energy on period;
wherein said short burst periods and said short rest periods are relatively brief in duration as compared with said long off period.

Abstract
A method and apparatus for delivering energy during a surgical procedure such as phacoemulsification is provided. The method and apparatus include applying energy during at least one pulsed energy on period, comprising applying energy during a series of short burst periods, the short burst periods interspersed by short rest periods. The method and apparatus further comprise delivering minimal energy during a long off period, the long off period comprising a relatively long period when minimal energy is applied, wherein one long off period follows each pulsed energy on period. The short burst periods and the short rest periods are relatively brief in duration as compared with the long off period.

9. A method of delivering ultrasonic energy during a tissue removal procedure, comprising:
delivering pulses of ultrasonic energy during an on period, energy pulse delivery comprising; delivering at least one relatively short burst of energy; and pausing for at least one relatively short period; and pausing for a relatively long off period after said on period and prior to commencing any subsequent on period, wherein pausing for each relatively, short period and for the relatively long off period comprises applying minimal energy therein; wherein each relatively long off period automatically occurs after each on period and occurs in the absence of external energy level reduction activities. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
