The device comprises an outer conductor (7) and an inner conductor (9) arranged approximately coaxial with each other. The outer conductor surrounds the inner conductor. The outer conductor (7) and the inner conductor (9) are arranged and configured to generate an electromagnetic field with lines of force extending from a front surface (9A) of the inner conductor (9) to a front surface (7C) of the outer conductor (7). The device further comprises an energy delivery window (13) arranged in front of the outer conductor and the inner conductor.

A method for determining a change of temperature of an object. The method may include heating an object and measuring scattering parameters (S-parameters) of scattered microwave electric fields from the object. A distorted Born iterative method may be used to determine a change of a dielectric property of the object based on the measured S-parameters. A change of temperature of the object may be determined based on the change of the dielectric property of the object.

A flexible catheter is inserted into the esophagus to cool or warm the esophagus, particularly during certain procedures which can tend to change the temperature in the area of the esophagus. The catheter is inserted through the mouth and throat to a position, for example, proximate the heart, but within the esophagus. One or more balloons are inflated to block areas of the esophagus, while a gel is injected into the esophagus where it is immobilized by the one or more balloons. A coolant is pumped through a coolant tube affixed to the catheter, where it exchanges heat with the conductive gel.

An evacuation system and method for removing and/or treating gaseous and/or particulate byproducts of surgical procedures includes an end effector such as a side vent trocar, an operating room tower or the equivalent, a disposal vessel, a vacuum source and optionally a filter. The end effector may be coupled to the tower by a conduit, the tower may be coupled to the collection tank by a conduit, and the collection tank may be coupled to the vacuum source. Gaseous and/or particulate byproducts may flow from the surgical site through the trocar, conduits, tower tank and filter, and the flow may be regulated at least in part by the components of the system.

An ultrasound device includes an ultrasound body having a shaft and an ultrasound sensor assembly disposed at a distal end portion of the shaft. The ultrasound sensor assembly is configured to enable ultrasound imaging. A clip is configured for positioning about a portion of a surgical tool. The clip is configured to releasably engage the ultrasound body to thereby releasably couple the surgical tool with the ultrasound body. A surgical system includes the ultrasound device and the surgical tool.

Disclosed is a plasma skin care device including a handpiece, an ozone decomposition module, and a suction fan. The handpiece has a plasma generator and discharges plasma in a state in which a front end portion of the plasma generator is adjacent to skin. The ozone decomposition module is configured to receive and decompose ozone, which is generated when the plasma is discharged, from the handpiece. The suction fan is configured to draw the ozone generated in the handpiece to the ozone decomposition module by suction pressure.

An apparatus for administering a cancer drug, comprising an optical emitter operatively arranged to emit a visible point of light onto a tissue surface to be treated, a robotic arm, operatively arrange to move a drug-delivery device, in sequence, to each of a plurality of predetermined positions within the tissue to be treated, a tactile sensor operatively arranged at the distal end of the drug-delivery device to determine vertical height movement of the robotic arm for contact of the tissue surface to be treated, a reservoir arranged to store the cancer drug, a needle, operatively arranged to be moved to each of the specific positions within the tissue, and to deliver the drug at those positions, and, a torch head for generating non-thermal plasma in proximity to an end of the needle and the area to be treated.
