Abstract: Systems and methods for endometrial ablation. The systems include a handle and elongated introducer sleeve extending to an expandable working end having a fluid-tight interior chamber. A thin dielectric wall surrounds at least a portion of the interior chamber and has an external surface for contacting endometrial tissue. The thin dielectric wall surrounds a collapsible-expandable frame and receives an electrically non-conductive gas. First and second polarity electrodes are exposed to the interior and exterior of the chamber, respectively. A radiofrequency power source operatively connects to the electrode arrangement to apply a radiofrequency voltage across the first and second electrodes, wherein the voltage is sufficient to initiate ionization of the neutral gas into a conductive plasma within the interior chamber, and to capacitively couple the current in the plasma across the thin dielectric wall to ablate endometrial tissue engaged by the external surface of the dielectric structure.

Abstract: A surgical fluid management system includes a console and a cassette for delivering fluids to a surgical site. The console has a pump rotor and a pressure-sensing membrane. The cassette has a cassette housing, a flexible fluid delivery tube in the housing. The flexible fluid delivery tube has a lumen configured to interface with the pump rotor and to deliver a flow of fluid from a fluid source as the rotor is rotated. A pressure-transmitting membrane is located in a wall of the cassette housing and in fluid communication with said fluid delivery lumen. The pressure-transmitting membrane flexes outwardly in response to a positive pressure in the lumen and flexes inwardly in response to a negative pressure in the lumen. The pressure-transmitting membrane detachably adheres to or presses against the pressure-sensing membrane to cause the pressure-sensing membrane to move in response to pressure changes in the flexible fluid delivery tube.

Abstract: A medical instrument includes a tubular cutter extending along an axis and having a windowed outer sleeve and a moveable inner cutting sleeve. An ultrasound transducer is operatively coupled to the inner cutting sleeve in order to induce motion in the inner cutting sleeve to enhance cutting or resection of tissue by the inner cutting sleeve as it is reciprocated or otherwise moved past the cutting window. The instrument typically will include a motor drive configured to reciprocate and/or rotate the inner cutting sleeve relative to the windowed outer sleeve, usually at a reciprocation rate between 1 and 10 Hz.

Abstract: A gas injector used for semiconductor equipment includes a housing shell, a rotating main shaft and a gas output distribution unit. The rotating main shaft is covered with the housing shell, and includes a plurality of magnetic fluid seals and a plurality of gas transmission tubes. The gas output distribution unit is coupled to a top end of the rotating main shaft, the gas output distribution unit being connected to a ceiling and a susceptor. The gas output distribution unit includes a plurality of boards spaced at intervals between the ceiling and the susceptor, thereby resulting in a plurality of gas output layers for outputting corresponding reaction gases.

Abstract: Tissue is treated using a radiofrequency power supply connected to an applicator having a chamber filled with an electrically non-conductive gas surrounded by a thin dielectric wall. A radiofrequency voltage is applied at a level sufficient to ionize the gas into a plasma and to capacitively couple the ionized plasma with the tissue to deliver radiofrequency current to ablate or otherwise treat the tissue.

Abstract: Medical devices and methods for treating and occluding a female patient's fallopian tubes to provide permanent birth control or sterilization.

Abstract: A detachable gas injector adaptable to semiconductor equipment includes a top cover, a hollow sleeve, a top housing and a gas output unit. The hollow sleeve receives a convex part of the top cover, thus forming a first transmission passage between the hollow sleeve and the convex part. The top housing has a center hole for accommodating the hollow sleeve, thus forming a second transmission passage between the hollow sleeve and the center hole. The gas output unit is connected to a bottom surface of the hollow sleeve. The gas output unit includes a first partition plate and a second partition plate, which form a first gas output layer, a second gas output layer and a third gas output layer.

Abstract: A fluid management system receives fluid from a fluid source and delivers the fluid to a medical probe having a first fluid infusion and aspiration circuit and a second fluid infusion and aspiration circuit. The system also transfers fluid from the medical probe to a collection container. A controller operates a first pump and valve assembly to selectively deliver fluid inflow from the fluid source to one of the first fluid infusion and the second fluid infusion and aspiration circuit. The controller further operates a second pump and valve assembly to selectively transfer fluid outflow to the collection container from one of the first fluid infusion and aspiration circuit of the medical probe and the second fluid infusion and aspiration circuit of the medical probe.

Abstract: The present invention is directed to an assembling device used for semiconductor equipment. The assembling device includes a chamber lid, a ceiling, a suspension part, a driving part and receptacles. The ceiling is disposed below the chamber lid. The suspension part is inserted through the chamber lid, and to be hooked to the ceiling. The driving part is disposed above the chamber lid and connected to the suspension part, and configured to drive the suspension part to join or separate the ceiling and the chamber lid. The receptacles are disposed in the ceiling and configured to be correspondingly attached to the suspension part, each of the receptacles defines a rotating groove that is open at top and closed at bottom.

Abstract: A tissue resecting device includes a handle coupled to an elongated sleeve assembly. The elongated sleeve assembly includes a windowed outer sleeve and an inner sleeve adapted to reciprocate and/or rotate relative to the window to resect tissue intruding into the window, where the resected tissue is captured in a channel in the sleeve assembly. One or more motors in the handle both move the inner sleeve relative to the window and operate a pump which causes a fluid to flow through the channel in the sleeve assembly to remove resected tissue therefrom.

Abstract: A vaporizer includes a rigid rectangular housing having a length, a width, a height, a proximal end, and a distal end. A battery is positioned in the rectangular housing. An inline USB connection is positioned inside the rectangular housing at the proximal end in a fixed position such that the inline USB connection does not extend outside the rectangular housing. The advantageous inline USB connection is an improvement over existing USB connection methods, providing but not limited to fewer components, more stability, more protection, and a streamlined appearance.
