A method of dilating a target anatomical structure of an ear, a nose, or a throat of a patient includes inserting a distal end of a balloon catheter into the ear, the nose, or the throat. The balloon catheter includes a balloon assembly coaxially disposed along a proximally extending shaft. The balloon assembly includes at least first and second dilation balloons that at least partially overlap one another. The method also includes distally advancing the distal end until the balloon assembly is disposed in the target anatomical structure. The method also includes selectively dilating the target anatomical structure based on a diameter of the target anatomical structure by inflating the first dilation balloon to a first diameter or inflating the second dilation balloon to a second diameter that is greater than the first diameter. The second inflation lumen is not in fluid communication with the first inflation lumen.

Multi-balloon dilation catheter

An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes an activation member that is operable to move in a first direction to select a mode of operation. The shaft assembly extends distally from the body and includes an acoustic waveguide. The end effector includes an ultrasonic blade that is in acoustic communication with the acoustic waveguide. The activation member is operable to move in a second direction to activate the end effector in a mode of operation selected by movement of the activation member in the first direction.

Surgical instrument with multi-function button

An apparatus includes a body assembly, an acoustic waveguide, an ultrasonic blade, a liquid dispensing feature, and a control module. The liquid dispensing feature is positioned distally relative to the body assembly. The liquid dispensing feature is positioned adjacent to the ultrasonic blade. The liquid dispensing feature is configured to deliver a flow of cooling liquid to the ultrasonic blade. The control module is operable to regulate fluid flow through the liquid dispensing feature.

Features and methods to control delivery of cooling fluid to end effector of ultrasonic surgical instrument

Methods and devices are provided for retracting a cutting assembly in the event of a failure on a motorized electrosurgical device. A surgical device is provided that includes a handle portion with an elongate shaft extending distally therefrom. The elongate shaft has first and second jaws at a distal end, and the jaws are configured to engage tissue. The surgical device also has a cutting assembly configured to cut tissue engaged between the first and second jaws. A drive shaft extends from the handle of the surgical device through the elongate shaft and is coupled to the cutting assembly for moving the cutting assembly. The surgical device has a motorized gear assembly with at least one motor driven gear that is configured to move the drive shaft. The surgical device also has a bailout assembly that is configured to manually move the drive shaft.

Dual step bailout for motorized RF device

Methods and devices for controlling motorized surgical devices are provided. In general, the methods and devices can allow a surgical device to grasp and cut tissue. In some embodiments, the device's motor can begin providing power for grasping and/or cutting tissue in response to an output from the device's sensor, the device can adjust power provided by the motor based on whether the device is clamping tissue or is being fired, the device can adjust an amount of power provided by the motor based on an amount of user-applied force to the device's actuator and/or can control drive direction of the motor based on the amount of the force, the device can maintain a force applied to the device, the device can self-shift the motor, and/or the device can adjust an amount of power provided to the device's end effector based on a degree of the end effector's closure.
