International Classification:

A61B 17/32
A61B 18/14

Abstract:

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.

International Classification:

A61M 25/10

Abstract:

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.

Abstract:

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.
