Medical tool positioning and control devices, systems, and methods. Handle assemblies that allow a steerable shaft to be steered, while allowing the separate movement of a medical tool. The handle assemblies can allow for rotation and axial movement of the medical tool, and optionally with an actuator disposed distal to a second actuator that controls steering of the steerable shaft.

Medical tool positioning devices, systems, and methods of use and manufacture

An electrode structure and a mechanism for automated or user-selected operation or compensation of the electrodes, for example to determine tissue coverage and/or prevent arcing between bottom electrodes during electrocautery is disclosed.

Electrocautery method and apparatus

A method and apparatus for calculating current lost through a patient during a treatment of a patient using an electromagnetic energy delivery system is disclosed. The system generates electromagnetic energy, contacts a skin surface of the patient, transfers the electromagnetic energy to tissue beneath the surface of the skin, detects a value of at least one characteristic of the electromagnetic energy utilizing synchronous undersampling, and calculates the current lost through the patient. The characteristic measured may be a value of current of the electromagnet energy. An adjustable matching network may be utilized to maximize power to the tissue of the patient. Values of the impedance of the matching network may be utilized to determine the electromagnetic energy delivered to the tissue of the patient. A current correction factor is determined from the impedance of the matching network and utilized to calculate the current lost through the patient.

Method and apparatus for digital signal processing for radio frequency surgery measurements

Electrode assemblies and handpieces for energy-based treatment systems that utilize an impedance assembly to facilitate impedance matching between the system and a patient. The electrode assembly and/or handpiece may include one or more circuit elements configured to introduce at least one supplemental impedance into an electrical circuit coupling the electrode assembly and handpiece. The supplemental impedance, which is related to the impedance of the treatment system and patient, is introduced when the electrode assembly is coupled with the handpiece.
