Abstract: An electrosurgical resection instrument for applying to biological tissue radiofrequency electromagnetic energy has a protective hull comprising a shaped piece of dielectric material mounted to cover an underside of an instrument tip of the instrument. The protective hull acts as a shield to protect tissue that may lie under the instrument tip from damage during treatment. The instrument may be particularly useful in procedures performed in a gastrointestinal tract, where bowel perforation is a concern, or in the pancreas, where damage to the portal vein or the pancreatic duct may occur when a tumor or other abnormality is being resected, dissected or removed.

Abstract: In a high voltage, variable frequency radiation generation system, a carrier signal supplied to a primary coil of a transformer is varied, e.g., turned ON and OFF at variable frequencies. The ON duration and/or the average amplitude of the carrier signal may also be varied. Moreover, the carrier signal may be modulated using an audio signal. The parameters to control the variation of the carrier can be provided as a recipe via a software application. A server can provide different types of apps providing different control features. The server may also collect user characteristic data and recipe usage data, and may facilitate exchange of these data and may recommend recipes based on a particular user characteristic.

Abstract: A forceps includes an end effector assembly having first and second jaw members, each including a proximal flange and a distal jaw body defining a tissue-treating surface. The second jaw member is both proximally offset and spaced-apart from the first jaw member. One or more resilient bands extends between and interconnects the proximal flanges of the jaw members. The resilient band(s) is configured to bias the first and second jaw members towards an open position. The resilient band(s) is configured to flex in response to distal translation of the second jaw member relative to the first jaw member to thereby move the second jaw member relative to the first jaw member to a closed position for grasping tissue between the tissue-treating surfaces thereof. In the closed position, the second jaw member is disposed in an aligned orientation and is approximated relative to the first jaw member.
