20100114009 | VACUUM SENSE CONTROL FOR PHACO PULSE SHAPING - A method and apparatus for precisely controlling particle movement relative to a phacoemulsification needle tip is provided. The design monitors actual vacuum present and calculates a pulse shape amplitude waveform proportional to the amount of measured vacuum. An increase in vacuum indicates that the handpiece/needle is becoming occluded by a large particle. The present design determines whether additional power is required to bump or move a large particle away from the needle tip. The present design may employ a control loop that senses and continuously monitors vacuum. The design may dynamically vary the amount of ultrasonic energy delivered to the surgical area in response to the observed actual vacuum, and can actively vary the amount of power delivered to the surgical area based on the size of the particle and the resultant vacuum realized. | 05-06-2010 |

20130072853 | SYSTEMS AND METHODS FOR CONTROLLING VACUUM WITHIN PHACOEMULSIFICATION SYSTEMS - The invention relates to systems and methods for controlling vacuum within phacoemulsification systems. The phacoemulsification system may include a handpiece having a needle. The needle is coupled to a power source configured to cause the needle to be ultrasonically vibrated during operation and an aspiration source. The system further includes a footpedal that defines a first position and a second position. The system also includes a computer program product operatively coupled to the handpiece and the footpedal, the computer program product having a computer-usable medium having a sequence of instructions which, when executed by a processor, causes said processor to execute a process that controls power from the power source and vacuum from the aspiration source applied to the handpiece. The process includes the steps of providing a vacuum at a first level to the handpiece when the footpedal is at the first position; providing power to the handpiece when the footpedal is at the second position; and reducing the vacuum to a second level when the footpedal transitions from the first position to the second position. | 03-21-2013 |
20130131611 | MEDICAL DEVICE RECEPTACLE FILLING METHOD AND APPARATUS - An apparatus and method for dispersing fluid from a fluid dispersal line is provided. The method comprises initiating operation of the medical apparatus, determining whether fluid has been dispersed from the medical apparatus via the fluid dispersal line since said initiating occurred, and assessing whether fluid is available in the fluid dispersal line. If fluid has not been dispersed from the medical apparatus since said initiating occurred and fluid is not available in the fluid dispersal line, the method includes distributing a commanded quantity of fluid plus an amount of fluid determined to fill the fluid dispersal line. Otherwise the method disperses only the commanded quantity of fluid. | 05-23-2013 |
