An ablation probe employs a triaxial construction with axial slots in an outer pair of tubular conductors separated by different dielectric materials to provide microwave power concentrated along a plane.

The invention relates to a cryoprobe. An apparatus includes a probe including a probe distal end having an outer surface that contacts tissue of a patient when the distal end is inserted into the body of the patient. A heater and a temperature sensor are located at the distal end, and a gas inlet is coupled to the distal end to provide gas. When the heater is activated, the controller records a first time when the temperature measured by the sensor is equal to or exceeds a preset temperature, and in response to the temperature equal to or exceeding the preset temperature, causes a pulse of gas to pass through the gas inlet so as to cool the distal end of the probe. The controller then records a second time when the temperature measured by the sensor is equal to or exceeds the preset temperature, and estimates a temperature of the outer surface of the distal end of the probe in response to a time difference between the second time and the first time.

The present invention relates to a tissue heating device, comprising: a body; a panel, used for contacting a tissue surface, installed at one end of the body and rotatable relative to the body; at least one working electrode, fixed on the panel, used for emitting radio frequency to heat the tissue surface; at least one cooling component, fixed on the panel and located at a different position from the working electrode. In the embodiment of the present invention, the working electrode and cooling component fixed on the panel will rotate around the rotation center of the panel at the same angular velocity as the panel. In this way, the effect of heating and cooling the surface of the tissue covered by the panel can be achieved, and the heat of the tissue surface can be quickly taken away, ensuring the effective heating of the deep fat tissue below the tissue surface and improving the comfort.

This invention relates to an energy harvester (7) and charger (1) system that utilizes rotating magnetic field technology to meet the energy needs of biomedical devices that are implantable into the body by a minimally invasive method. This technology aiming to solve the problem of battery depletion in devices such as pacemakers will significantly reduce the dependence on surgical interventions. The charger (1), electric motor (3), and permanent magnets (6) provide the energy harvester (7) with a variable magnetic field. The energy harvester (7) converts alternating current into direct current by generating electric current in its coil / coils (8) with this magnetic field. The generated energy is stored in a rechargeable battery (12) in accordance with the levels required by biomedical devices. The system works with low-frequency magnetic fields to keep SAR values within safe limits and minimizes negative effects such as tissue heating. It also ensures efficient energy production. The materials used in the energy harvester are biocompatible and toxic effects are avoided. The invention reduces the risks of surgery and increases patient comfort with its minimally invasive nature. It provides economic and health advantages by reducing the frequency of battery replacement of implantable devices such as pacemakers. It can also be used in other biomedical devices such as defibrillators, neurostimulators, cochlear implants, and retinal implants.
