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.

TL;DR: In this paper, a movable electrode within an array of multiple electrodes located within the body is guided to sense electrical or sonic energy in a predetermined fashion to generate an output that locates the movable node within the array.

TL;DR: In this paper, the authors present a system for ablating body tissue using an electrode for contacting tissue to form a tissue-electrode interface, where the electrode is adapted to be connected to a source of ablation energy.

TL;DR: An imaging structure has a periphery adapted to selectively assume an expanded geometry and a collapsed geometry, and the periphery of the imaging structure carries an array of spaced apart ultrasound transducers as discussed by the authors, which is called the periphery transducers.

TL;DR: In this article, a catheter tube carries an operative element, such as, an imaging element to visualize tissue, and a steering element moves the operative element relative to the support structure, while sensing spatial variations in the electric field during movement of the imaging element.
