Abstract
News editors obtained the following quote from the background information suppli ed by the inventors:“A variety of ultrasonic surgical instruments include an en d effector having a blade element that vibratesat ultrasonic frequencies to cut and/or seal tissue (e.g., by denaturing proteins in tissue cells). These instruments include one or more piezoelectric elements that convert electrical power i nto ultrasonic vibrations,which are communicated along an acoustic waveguide to the blade element. Examples of ultrasonic surgicalinstruments and related conc epts are disclosed in U.S. Pub. No. 2006/0079874, entitled “Tissue Pad forUse w ith an Ultrasonic Surgical Instrument,” published Apr. 13, 2006, now abandoned, the disclosure ofwhich is incorporated by reference herein, in its entirety; U. S. Pub. No. 2007/0191713, entitled “UltrasonicDevice for Cutting and Coagulatin g,” published Aug. 16, 2007, now abandoned, the disclosure of which isincorpora ted by reference herein, in its entirety; and U.S. Pub. No. 2008/0200940, entitl ed “UltrasonicDevice for Cutting and Coagulating,” published Aug. 21, 2008, now abandoned, the disclosure of which isincorporated by reference herein, in its entirety.
