An electrosurgical device is provided that includes a probe extending in a longitudinal direction and having a proximal region and a distal region. An inner diameter of the probe defines a lumen. The probe has an electrically insulated portion extending from the proximal region to the distal region and an electrically exposed conductive portion located at the distal region. The electrically exposed conductive portion delivers radiofrequency energy to an area of tissue adjacent the distal region. The device also includes a heat transfer system for removing thermal energy from the area of tissue that is in thermal contact with the area of tissue. The heat transfer system removes from about 0.1 Watts to about 50 Watts of energy from the tissue. In addition, the heat transfer system can sufficiently draw heat away from the tissue without the use of a peristaltic pump for circulating a liquid inside the lumen.

The present invention provides a semiconductor laser module and a method for application in noninvasive medical treatment. The module comprises a direct-output type semiconductor laser light source and a beam shaping device disposed in the light-exit direction of the direct-output type semiconductor laser light source. The beam shaping device comprises a light reflection component. The light reflection component is configured to enable laser beams outputted by the direct-output type semiconductor laser light source to be uniform. Based on the semiconductor laser module and the method provided in the present invention, the objective of treatment can be achieved by means of extracorporeal irradiation in a case in which no harm is done to a human body, costs are low, and the treatment effect is good.

Skin treatment apparatus comprising an energy applicator structure configured to establish heating or ablation at a predetermined and controllable (i.e. selectable) depth below a surface of skin tissue with which it is in contact. The applicator structure may receive a cooling medium and microwave frequency electromagnetic energy, which provide a combined treatment effect that results in heating or ablation in a zone beneath the skin surface. The applicator may be a waveguide (e.g. waveguide horn antenna) with internal shielding configured to provide a substantially uniform heating effect. The applicator may include a thermal camera to monitor treatment.

Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a catheter treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver an energy delivery element to a renal artery via an intravascular path. Thermal or electrical renal neuromodulation may be achieved via direct and/or via indirect application of thermal and/or electrical energy to heat or cool, or otherwise electrically modulate, neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers.

In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.

An electromagnetic beam scanning system and corresponding method of use is provided. The system includes a motor, a reciprocating mechanism, and a focus optic. The motor is configured to generate a rotational movement. The reciprocating mechanism is operatively coupled with the motor and configured to convert the rotational movement to a reciprocating movement including a plurality of strokes along a first scanned axis. The reciprocating movement has a constant speed over a portion of at least one stroke of the plurality of strokes. The focus optic is operatively coupled to the reciprocating mechanism such that the focus optic moves experiences the reciprocating movement of the reciprocating mechanism. The focus optic is configured to focus an electromagnetic radiation (EMR) beam incident upon the focus optic to a focus along an optical axis substantially orthogonal to the first scanned axis.

The present disclosure provides a device for cooling a living tissue that solves severe patient's waiting and clinic work load due to time-consuming anesthesia required by conventional therapies and significantly reduces psychological burden and pain of the patient for ocular anesthesia.

The invention provides an intelligent moxibustion device, comprising a vertically disposed barrel, an ash tower buckled with the barrel, a moxa stick driving unit and an intelligent control unit disposed in the barrel; wherein the moxa stick driving unit comprises a moxa stick sleeve and a stepping motor disposed above the moxa stick sleeve; the stepping motor drives the moxa stick to move up and down through the transmission of a gear; the intelligent control unit comprises a battery disposed above the stepping motor for powering the entire moxibustion device, a circuit board fixed above the battery, and a temperature sensor disposed in the ash tower, the battery being connected to the circuit board to provide power to the circuit board, the circuit board being connected to the temperature sensor through input and output terminals.

According to various embodiments, systems, devices and methods for modulating targeted nerve fibers (e.g., hepatic neuromodulation) or other tissue are provided. The systems may be configured to access tortuous anatomy of or adjacent hepatic vasculature. The systems may be configured to target nerves surrounding (e.g., within adventitia of or within perivascular space of) an artery or other blood vessel, such as the common hepatic artery.

An electrosurgical device is provided. The device includes a cooled probe, an introducer, and a side port for the introduction of liquid into a lumen defined by an outer diameter of the probe and an inner diameter of the introducer when the probe is positioned inside the introducer such that a distal end of the probe can contact a target site (e.g., the site near/adjacent the tissue to be treated). The side port can be connected to a syringe/other liquid introduction apparatus via tubing so that a liquid (e.g., a therapeutic agent, saline, etc.) can be injected into the lumen and can exit the distal region of the introducer so that it is delivered to the target site. Additionally, the syringe can be removed so that the tubing can serve as a vent during treatment with the electrosurgical device.
