An ablation catheter system includes: a catheter shaft; a balloon attached to the catheter shaft; a lumen extending through the catheter shaft in a longitudinal direction thereof and communicating with the interior of the balloon; a heating electrode and a temperature sensor provided in the interior of the balloon; a heater that applies electrical energy to the heating electrode; a pressure sensor; a balloon volume sensor; and a processor that calculates the estimated depth of ablation, using as variables, heating temperature of a generator, ablation time of the generator, a value of balloon pressure obtained from the pressure sensor and a value of balloon volume obtained from the balloon volume sensor.

The electrosurgical instrument (11) according to the invention comprises at least one electrode (15, 16) for electrically acting on biological tissue. The electrode is coupled with a radio frequency generator (20) that is arranged in direct proximity of electrode (15) and/or (16). The radio frequency generator oscillates in a self-controlled manner with a frequency between 100 kHz and 10 MHz and is preferably supplied by a constant or timely varying direct voltage. The instrument (11) is thus connected via a line supplying a low frequency voltage or direct voltage with a supplying source, e.g. an apparatus (19).

Graphical user interface system and method for displaying and controlling a surgical device, such as a device used in phacoemulsification procedures, are disclosed. A graphical user interface is displayed on a display screen and includes one or more representations of operating parameters, such as aspiration rate, vacuum, and power that are used to control the surgical device. A parameter is adjusted by moving a portion of a representation from a first location on the display screen to a second location on the display screen to change the operating parameter and control the surgical device.

The present application relates to a heating system, which has a power supply module (11), a regulatory module, electrically connected to the power supply module (11), for modulating the power supply module (11), and a heating module (13). The heating module (13) comprises a positioning device and a conductive device. The heating module (13) is electrically connected to the power supply module (11) and the regulatory module, and the conductive device is tightly wound around the positioning device.

The current invention concerns systems, devices and methods for the ablation of a ablation of the wall of one or more pulmonary veins (PV) from the inside, preferably transmural ablation and preferably at the level of the antrum. Hereby, one or more implant devices can be implanted in the vessels and can subsequently be heated by external energy-providing means.
