C. and greater than body temperature after having being layered on the tissue; and a cooling step in which the heated joining member or laminate body is cooled to body temperature or lower. A treatment system comprises a heating unit and the joining member or the laminate body.

A medical device includes a capacitive micromachined ultrasonic transducer (CMUT) array configured to emit ultrasound to target tissue, and at least one thermoelectric cooler mechanically coupled with the CMUT array and configured to cool non-target tissue heated by the ultrasound. The medical device may be implemented in a catheter together with a solid thermal conductor coupled to the thermoelectric cooler and extending along the catheter, to conduct heat away from the thermoelectric cooler. A catheter or catheter sleeve includes a tubular wall for insertion into a body channel, and at least one thermoelectric cooler coupled to the tubular wall for cooling the body channel wall. A catheter sleeve includes tubular casing for insertion into a body channel and capable of encasing a catheter, and at least one sensor coupled to the tubular casing for sensing one or more properties of the body channel wall, such as temperature and pressure.

The cooling device includes a plurality of cooling elements movable relative to each other to conform to the contour's of the subject's skin. The cooling elements have a plurality of controllable thermoelectric coolers. The cooling elements can be controlled to provide a time-varying cooling profile in a predetermined sequence, can be controlled to provide a spatial cooling profile in a selected pattern, or can be adjusted to maintain constant process parameters, or can be controlled to provide a combination thereof.

The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site. The present invention further relates to hypothermic linear stapling instruments configured to pre-cool the tissues being joined by staples.

The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site, especially when sealing an anastomosis between adjacent intestinal sections to improve tissue viability under hypoxia conditions, prevent tissue inflammation, and to prevent leakage. The present invention further relates to hypothermic circular stapling instruments configured to pre-cool the tissues being joined by staples.

An electrosurgical apparatus and method for performing thermal treatment in the gastrointestinal tract, e.g. to ablate duodenal mucosal tissue. The apparatus comprises an instrument having a flexible cable and an applicator suitable for use with a gastroscope, which can be deployed within a patient to delivery energy in a targeted or otherwise controllable manner. The applicator can deliver microwave energy by radiation. The direct and depth-limited nature of microwave energy can be make it more effective than treatments that rely on thermal conduction. The applicator may include a radially extendable portion arranged to move an microwave energy delivery structure into contact with duodenal mucosal tissue at the treatment region. The applicator may comprise any of a balloon, bipolar radiator, movable paddle, and rotatable roller element.

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.

The present disclosure provides a hair removing device, including: a reflector; a light source; a light-transmitting body; a heat dissipation assembly, being connected to the light-transmitting body and configured to absorb heat from the light-transmitting body; a cold drive assembly, being configured to absorb external air, then blow into at least two cooling channels, and expel the air out of the hair removing device; cooling channels, comprising a first cooling channel and a second cooling channel; wherein at least one of the light source, the reflector is disposed in the first cooling channel, and at least part of the heat dissipation is disposed in the second cooling channel. Such that heat of the light source is dissipated uniformly, the service life of the light source is extended. Further, the improved heat dissipation performance allows the user to use the hair removing device more comfortably.
