Publication number: 20090299409Abstract: Various exemplary methods and devices are provided for tensioning sutures. The methods and devices are particularly useful in surgical suturing applications in which it is desirable to maintain tension on a suture being delivered. In various embodiments, the device is incorporated into the handle of a suture device configured to deliver a suture to a surgical site. Other embodiments comprise a device that is separate from, but may be used in connection with, a suture device configured to deliver a suture to a surgical site. A suture locking device is also provided which enables the surgeon to ascertain when a desired amount of tension has been applied to a suture prior to affixing knotting tying elements thereto.Type: ApplicationFiled: May 30, 2008Publication date: December 3, 2009Applicant: Ethicon Endo-Surgery, Inc.Inventors: Jonathan A.

Publication number: 20090118751Abstract: The present invention provides a system for surgery which includes an ultrasonic hand piece having a end-effector, a console having a digital signal processor (DSP) for controlling the hand piece, and a memory disposed in the end-effector. The generator console sends a drive current to drive the hand piece which imparts ultrasonic longitudinal movement to the blade. As the generator console reads the memory, the hand piece is authenticated for use with the generator console if a copyrighted data string is present in the memory. In a particular embodiment, the data string is an encrypted code, where the hand piece is authenticated for use with the console by decoding a corresponding encryption algorithm resident in the generator console and providing a responding data pattern.Type: ApplicationFiled: August 23, 2007Publication date: May 7, 2009Inventors: Eitan T. Wiener, Robert P. Gill, William T. Donofrio, Richard F. Schwemberger
