摘要： The invention relates to an ablation catheter for treatment of a patient's tissue, for example for a PVI procedure on a patient's heart, comprising an elongated catheter shaft and an ablation portion being arranged at a distal end of the catheter shaft with a plurality of electrodes accommodated along the ablation portion, wherein the ablation portion comprises at least two loop sections forming a three-dimensional spiral. In order to increase safety of ablation treatment, spare adjacent tissue (e.g. nerves, vessels, esophagus) and shorten ablation time, a pitch, or clearance of two neighboring loop sections is greater than an ionization threshold of the medium around the distal section, for example blood or gases resulted from electrolysis. The invention further relates to an operation method of such ablation catheter.

摘要： A physiological data acquisition system includes at least one interface module and a base unit configured to communicatively connect to the at least one interface module to receive the physiological signals recorded by a catheter. Each interface module is formed by mating at least a first one of the two or more different personality modules to a dock. The dock has a multi-modal connection port configured to directly connect to a dock connector of any one of the two or more different personality modules so as to receive physiological signals therefrom. The first personality module includes a first catheter connector configured to receive a connection end of the catheter so as to receive physiological signals therefrom, and a first dock connector configured to connect to the multi-modal connection port of the dock so as to provide the physiological signals thereto.

摘要： An ablation applicator for an ablation device for ablating tissue of a blood vessel having a tubular body defining an inner lumen to which an ablation medium is conductible, a control mechanism for converting the tubular body between a passive operation mode for inserting the ablation applicator into the blood vessel and an active operation mode for ablating tissue of the blood vessel, and an ablation medium supply line for supplying the ablation medium to the inner lumen and positioned within the inner lumen and having a number of openings for passing the ablation medium from the ablation medium supply line to the inner lumen for thermally contacting the ablation medium with the tubular body wherein at least some of the openings are distributed along the ablation medium supply line with a predetermined spacing between neighboring openings. The ablation device can include a first temperature sensor arranged within the inner lumen and an ablation medium return line inside the tubular body made from a material that defines the active shape of the applicator.

摘要： The present invention resides in one aspect in a device for monitoring luminal esophageal temperatures in a patient. The device includes a probe adapted to be inserted into an esophagus of the patient. The probe extends between a proximal end and a distal end. A first temperature sensor and a second temperature sensor are coupled to the probe. An electrode is also coupled to the probe. The second temperature sensor is displaced from the first temperature sensor along a longitudinal axis of the probe. A controller processes information received by the electrodes and the temperature sensors. The controller generates a live and continuously updating three dimensional anatomic map and three dimensional thermal map of the esophagus based at least in part on the information received from the temperature sensors and the electrodes. The thermal map and the anatomic map are displayed on a video monitor.

摘要： A method includes, receiving: (i) a selected three-dimensional (3D) section that has been ablated in a patient organ in accordance with a specified contour, and (ii) a dataset, which is indicative of a set of lesions formed during ablation of the selected 3D section. The selected 3D section is transformed into a two-dimensional (2D) map, and checking, on the 2D map, whether the set of lesions covers the specified contour.
