Abstract: The invention relates to a heating and/or cooling device (10) for delivering heating and/or cooling energy to the body of a living being (28). The heating and/or cooling device (10) comprises a heating and/or cooling pad (12) which can be connected to the body of the person (28). The heating and/or cooling pad has an upper face (122) and a lower face (121), and an adhesive surface (1210) is provided on the lower face (121) for attaching the heating and/or cooling pad (12) to the surface of the skin of the person (28). The heating and/or cooling pad comprises at least one heating and/or cooling element (26) by means of which electrical energy output by an electrical energy source (22) can be converted into heating and/or cooling energy. The heating and/or cooling device (10) further comprises a control unit (14) which is provided for fixedly or detachably accommodating the energy source (22) and has a signal processor (16).

Abstract: A cryoablation catheter, including a first capsule body, a core tube and a heat insulation part, wherein the first capsule body is mounted at a front end of the core tube, and has a front end area adapted for fitting to myocardial tissue during a cryoablation process and a rear end area exposed to blood; the core tube has a first looping path provided therein which is adapted for a first fluid with low temperature to be filled into or flow out of the first capsule body; the heat insulation part is at least partially fitting to the rear end area, and is adapted for reducing heat exchange efficiency between the first fluid and the blood in an atrium. The cryoablation operating apparatus and the cryoablation equipment thereof can effectively reduce the heat exchange between the cryoablation catheter and the blood during a cryoablation process.
