Abstract: A surgical system includes a fluid source, an ultrasonic transducer, an ultrasonic waveguide coupled to and extending distally from the ultrasonic transducer, and an ultrasonic blade disposed at a distal end of the ultrasonic waveguide and configured to receive ultrasonic energy produced by the ultrasonic transducer and transmitted along the ultrasonic waveguide to vibrate the ultrasonic blade for treating tissue therewith. The ultrasonic blade is configured to connect to a source of electrosurgical energy for conducting electrosurgical energy to tissue to treat tissue. The ultrasonic blade defines a lumen extending at least partially therethrough to at least one opening. The lumen is configured for fluid communication with a fluid source to enable the delivery of fluid from the fluid source through the lumen and out the at least one opening into a surgical site to facilitate electrosurgical tissue treatment.

Abstract: An improved system and method of endobronchial imaging of lung nodules comprises the introduction of a perfluorocarbon (PFC) liquid into pulmonary passages of the lungs, the introduction of which enables better coupling between an endobronchial ultrasonic imaging system and a target tissue site within the pulmonary passages of the lungs, the improved coupling between the ultrasonic imaging system and a target tissue site being imparted by the removal (at least in part) the air interface present between the ultrasonic imaging system and the surface of the target tissue site. Furthermore, the unique properties of perfluorocarbon liquids (for example, the properties of superb biocompatibility, high affinity for dissolving oxygen, and extremely low surface tension) further position these substances to be particularly well-suited for this application.

Abstract: An apparatus includes a handle, a catheter, an end effector, and a deflection drive assembly. The end effector includes at least one electrode. The deflection drive assembly includes an input member, a translating assembly coupled to the end effector, and a rack and pinion assembly. The rack and pinion assembly is configured to drive the translating assembly to deflect the end effector away at an angle relative to the longitudinal axis and consists of a rack and a pinion. The rack and pinion assembly is configured to either transfer rotational motion of the pinion from the input member into linear motion of the rack to push distally or pull proximally the translating member; or transfer linear motion of the rack from the input member into rotational motion of the pinion to move a first end of the translating member proximally and a second end of the translating member distally.
