International Classification:

A61M 35/00

US Classification:

604290, 417 3

Abstract:

An apparatus for controlling vacuum pressure is provided. The apparatus includes a multiple axis controller, such as a dual axis footpedal, and a processing apparatus, such as an instrument host running software, configured to receive multiple axis data from the multiple axis controller. The apparatus also includes a first pump configured to provide nonzero fluid pressure at a first nonzero fluid pressure level based on a first axis state of the multiple axis controller and a second pump configured to provide nonzero fluid pressure at a second nonzero fluid pressure level based on a second axis state of the multiple axis controller. The processing apparatus causes switching between the first pump and the second pump based on the first axis state and the second axis state of the multiple axis controller.

US Classification:

604 22, 606 1, 74512, 700 86

Abstract:

The present invention pertains to programming a foot pedal and switches located therewith that is used with a medical device and/or medical device system. A user may select any switch or directional movement available on the foot pedal for programming by activating the switch and/or moving a treadle located on the foot pedal or by selecting a foot pedal feature on a display. The programming options available for the selected switch or directional movement are displayed on the display screen. Using the foot pedal, the display screen, voice command or combinations thereof, the user can navigate through different options to select one or more options and confirm the chosen option(s) for the particular switch or directional movement. The control and feel of the movement of the treadle and/or switch provides the user with the ability to program custom settings that suit the user's foot position(s) and/or particular style of surgery.

International Classification:

A61F 9/007

US Classification:

604 22

Abstract:

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.

International Classification:

A61F 9/007

US Classification:

604 22, 604500, 604 67

Abstract:

An apparatus and method for controlling fluid flow provided by an apparatus to a patient's eye during a surgical procedure. The method includes automatically adjusting an irrigation fluid source to a predetermined height during the surgical procedure using the apparatus, receiving a request either that the irrigation fluid source be moved to a different height from the predetermined height or that a manual adjustment mode be entered, and ceasing automatic adjusting and requiring manual adjustment of the height of the irrigation fluid source until the surgical procedure is completed or an indication received to resume automatic height adjustment of the irrigation fluid source. As an alternative, fluid flow rate or intraocular pressure may be maintained, and the design may include making adjustments to default values in other modes based on the adjustment made.

A61M 1/00

Abstract:

Methods and systems for automatically pulsing different aspiration levels to an ocular probe are disclosed. The probe may be a phacoemulsification probe. A first aspiration level, supplied by a first pump, may be applied to the probe simultaneously with ultrasonic energy. A second aspiration level, supplied by a second pump, may be automatically switched from the first aspiration level, and applied to the probe in a pulsed manner.
