20110218433 | Biopsy Marker Delivery Device - A biopsy site marker delivery device includes a relatively flexible marker deployer tube having a closed distal end, a push rod slidably disposed within the tube, and at least one marker disposed in the tube. The deployer tube includes a side exit port with an adjacent ramp for transversely dispensing the marker upon distal advancement of the push rod within the tube. An elongate member such as a sleeve is operable to guide and/or stabilize the flexible deployer tube as the tip of the tube is inserted into an access channel such as a channel provided by a cannula or biopsy device. An internal package member is configured to support the marker delivery device and the elongate member, with the elongate member being positioned over the side exit port to prevent the marker from inadvertently exiting the side exit port. The package member may reside in a sterile packaging envelope | 09-08-2011 |

20140330298 | CLAMP ARM FEATURES FOR ULTRASONIC SURGICAL INSTRUMENT - A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The shaft assembly comprises an inner tube configured to longitudinally translate to thereby pivot the clamp arm toward and away from the ultrasonic blade. A distal portion of the inner tube is operable to flex to thereby accommodate pivoting of the clamp arm. | 11-06-2014 |
20150080925 | ALIGNMENT FEATURES FOR ULTRASONIC SURGICAL INSTRUMENT - An ultrasonic instrument comprises a body, a shaft assembly, an ultrasonic blade, and a pivoting member. The shaft assembly extends distally from the body. The ultrasonic blade is positioned distal to the shaft assembly. The pivoting member is pivotable with respect to the blade from an open position to a closed position to thereby clamp tissue between the pivoting member and the blade. One or both of the shaft assembly or the pivoting member comprise a guide feature. The guide feature is configured to provide lateral alignment of the distal portion of the pivoting member with the blade as the pivoting member is pivoted to the closed position. | 03-19-2015 |
