Abstract: Embodiments of the present invention generally relate to methods, devices, and systems for reducing a pigmentation of a skin of a patient. In some embodiments, freezing of the skin may be desirable to effect the hypopigmentation of the skin of the patient. Generally, embodiments may limit supercooling (or promote freezing) of the skin of the patient during a cooling treatment. In some embodiments, coupling fluids are provided to reduce a thermal contact resistance between a cooling treatment probe and the skin of the patient to improve cooling treatment. Optionally, a fluid carrier may be provided to help retain the coupling fluid at the treatment site. In some embodiments, the coupling fluid may include ice nucleating agents to promote ice crystal formation in the coupling fluid during cooling treatment. The ice crystal formation in the coupling fluid may progress into the skin to limit supercooling of the skin during treatment.

Abstract: Microwave-irradiating surgical instruments for endoscopic forceps or scope-assisted surgery forceps that have long lead wires often generate heat even during microwave transmission and a water supply device for cooling is necessary. Accordingly, conventional surgical instruments that irradiated energy such as microwaves had a separate passage for passing water (a water supply device) inside the forceps or endoscope. Due to the space occupied by said water supply device, the image cable or work hole diameter could not be enlarged. Moreover, the presence of the water supply device made surgery difficult. The present invention was completed by the discovery that a microwave-irradiating instrument wherein the central conductor is hollow and forms a channel and said channel is used as a water supply tube, etc. solves the above problems without affecting microwave irradiation efficiency.
