Abstract:
A process and system are disclosed for downloading sensor data, stored in a memory device of a surgical cutting and fastening instrument (10), to an external or remote computer device (2420). The process may involve storing data from one or more sensors of a surgical cutting and fastening instrument in a memory device (2406) of a control unit (2400) of the surgical cutting and fastening instrument during a surgical procedure involving the surgical cutting and fastening instrument. Next, after the surgical procedure, a data link (2422) between the control unit and the remote computer device is established. Then, the sensor data can be downloaded from the control unit to the remote computer device.

Abstract:
An inflatable medical instrument (18) for tissue damage in gastric reduction surgery includes a main chamber (20) composed of a biocompatible material capable of being selectively inflated. The medical instrument also includes a longitudinally extending tab member (26) secured to an outer surface of the main chamber, a series of suction holes (30) are formed along the tab member and an electrode (38) is mounted on the tab member. The present invention also provides a method for forming a tissue junction used in defining a gastric pouch including damaging opposed tissue layers, apposing the tissue layers and fastening the tissue layers to allow the tissue layers to heal together.
Abstract:
Various embodiments are directed to an apparatus, system, and method for driving an end effector coupled to an ultrasonic transducer in a surgical instrument. The method comprises generating a first ultrasonic drive signal by a generator coupled to an ultrasonic drive system, actuating the ultrasonic transducer with the first ultrasonic drive signal for a first period, generating a second ultrasonic drive signal by the generator, and actuating the ultrasonic transducer with the second ultrasonic drive signal for a second period, subsequent to the first period. The first drive signal is different from the second drive signal over the respective first and second periods. The first and second drive signals define a step function waveform over the first and second periods. The apparatus comprises a generator configured to couple to an ultrasonic instrument. The system comprises a generator coupled to an ultrasonic instrument. The ultrasonic instrument comprises an ultrasonic drive system comprising an ultrasonic transducer coupled to a waveguide and an end effector coupled to the waveguide, and wherein the ultrasonic drive system is configured to resonate at a resonant frequency.
Abstract:
A surgical generator (102) that may produce a drive signal or signals of particular voltages, currents, and frequencies, e.g. 55,500 cycles per second (Hz). The drive signal or signals may be provided to an ultrasonic surgical device (104), and specifically to a transducer. In one embodiment, the generator may be configured to produce a drive signal of a particular voltage, current, and/or frequency that can be stepped with high resolution, accuracy, and repeatability. Additionally, the surgical generator may generate a drive signal or signals with output power sufficient to perform bipolar electrosurgery using radio frequency (RF) energy. The drive signal may be provided, for example, to electrodes of the electrosurgical device (106). Accordingly, the generator may be configured for therapeutic purposes by applying electrical signals to an ultrasonic transducer or electrical energy to the tissue sufficient for treating the tissue (e.g., cutting, coagulation, cauterization, tissue welding).
