TL;DR: 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.

TL;DR: In this paper, a support body with multiple electrodes was designed to increase the density of the electrodes per given tissue area. But the support body can carry either elongated, continuous electrodes or arrays of non-contiguous, segmented electrodes.
Abstract: Systems and associated methods form larger and deeper lesion patterns by shaping a support body with multiple electrodes in ways that increase the density of the electrodes per given tissue area. The support body can carry either elongated, continuous electrodes or arrays of non-contiguous, segmented electrodes.

TL;DR: In this article, a bendable catheter tube is carried for sliding movement in the interior bore, and a pull wire also runs through the internal bore of the sheath, preferably within a lumen.
Abstract: A catheter assembly having a sheath, which includes a side wall enclosing an interior bore, and a distal region. The assembly also has a bendable catheter tube, which is carried for sliding movement in the interior bore. A pull wire also runs through the interior bore of the sheath, preferably within a lumen. The catheter tube has a distal portion with a coupling which joins the distal portion of the catheter tube and the distal portion of the pull wire. Relative movement of the pull wire and the sheath causes bending of the catheter tube outwardly through the opening, in response to sliding movement of the catheter tube within the interior bore toward the distal region of the sheath.

TL;DR: In this paper, the authors place a temperature sensing element in an edge region between an energy transmitting electrode and a non-electrically conducting support body, where higher temperatures are likely to exist.
Abstract: Systems and associated methods place a temperature sensing element in an “edge region” between an energy transmitting electrode and a non-electrically conducting support body, where higher temperatures are likely to exist. Reliable temperature sensing, which is sensitive to variations in temperatures along the electrode, results.

TL;DR: In this article, a surgical stapling device particularly suited for endoscopic procedures is described, which includes a handle assembly and an elongated body extending distally from the handle assembly.
Abstract: A surgical stapling device particularly suited for endoscopic procedures is described The device includes a handle assembly and an elongated body extending distally from the handle assembly The distal end of the elongated body is adapted to engage a disposable loading unit A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device

TL;DR: An endoscopic bipolar forceps as mentioned in this paper includes an elongated shaft having opposing jaw members at a distal end thereof, which are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to each another to a second position wherein jaw members cooperate to grasp tissue therebetween.
Abstract: An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The forceps also includes a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A generally tube-like cutter is included which is slidably engaged about the elongated shaft and which is selectively movable about the elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.

TL;DR: In this paper, a surgical stapling device for applying an array of surgical staples to tissue is provided, which includes an approximation mechanism for moving a cartridge assembly and an anvil assembly between spaced and approximated positions and a firing mechanism for ejecting the array of staples from the cartridge assembly.
Abstract: A surgical stapling device for applying an array of surgical staples to tissue is provided. The stapling device includes an approximation mechanism for moving a cartridge assembly and an anvil assembly between spaced and approximated positions and a firing mechanism for ejecting the array of staples from the cartridge assembly. A single trigger is operable to effect approximation and firing of the device. The device also includes an alignment pin assembly which can be selectively manually or automatically advanced. The anvil assembly includes a stiffener plate which allows the device to have a reduced head portion profile.
