Systems and methods for controlling power in an electrosurgical probe
TLDR
In this paper, the power control of an electrosurgical probe is discussed, where the power is adjusted in response to a loss of contact, and applied in such a way that charring, coagulum formation and tissue popping are less likely to occur.Abstract:
Systems and methods for controlling the power supplied to an electrosurgical probe. The systems and methods may be used to monitor electrode-tissue contact, adjust power in response to a loss of contact, and apply power in such a manner that charring, coagulum formation and tissue popping are less likely to occur.read more

Powered surgical instrument
Michael Zemlok,David C. Racenet +1 more
TL;DR: In this paper, a handle assembly, a first endoscopic portion, a motor, and a first effector are described, and the first end effector is configured to perform a first stapling function.
Patent
Electrosurgical generator with adaptive power control
TL;DR: In this article, an electrosurgical generator has an output power control system that causes the impedance of tissue to rise and fall in a cyclic pattern until the tissue is desiccated.
Patent
Fluid-assisted medical devices, systems and methods
TL;DR: In this article, the authors describe an exemplary surgical device for treating tissue and methods of treating tissue, which includes a handle, a fluid passage connectable to a fluid source, a tip portion and a distal end.
Patent
Surgical stapler with timer and feedback display
Frank J. Viola,Gregg Krehel,Michael A. Soltz,Robert J. Desantis,Henry E. Holsten,Russell Heinrich +5 more
TL;DR: In this paper, a surgical apparatus has a clamp and a stapling mechanism, which is controlled by a trigger handle or a switch assembly, and an indicator provides feedback about the status of the staplings mechanism and also displays a time of tissue compression by the clamp.

Articulating endoscopic surgical apparatus
TL;DR: In this article, a surgical instrument is provided for use in endoscopic or laparoscopic procedures, which includes a handle portion, an endoscopic portion extending from the handle, an articulating section pivotably connected to a distal end portion of the endoscopic part, and a retractor assembly operatively associated with the articulating part.
Patent
Methods and apparatus for surgical cutting
TL;DR: An electrosurgical probe comprises a shaft having an electrode array (12) at its distal end and a connector at its proximal end as mentioned in this paper, which is used to cut or ablate target tissue while heat dissipation through low impedance paths.
Patent
Electrode and associated systems using thermally insulated temperature sensing elements
Stuart D. Edwards,Roger A. Stern +1 more
TL;DR: A thermal insulating element associated with the sensing element blocks the transfer of heat energy from between the temperature sensing element and the body as discussed by the authors, therefore measuring temperature without being affected by the surrounding thermal mass of the electrode.
Patent
Thin layer ablation apparatus
TL;DR: In this article, an expandable member is inserted into an organ of a body and ablates all or a selected portion of the inner layer of the organ, and a feedback device is included and is responsive to a detected characteristic of the internal layer.
Patent
Impedance feedback electrosurgical system
Paul C. Nardella,David C. Yates +1 more
TL;DR: In this paper, an impedance feedback electro-surgical system (100) is used to maintain a preselected control range of tissue impedance within the tissue in contact with the tool.
