In another switching position, the inlet is connected to a plurality of the outlets. The inlet of the valve device is in fluid communication with a first flow path and the outlets are in fluid communication with another flow path. Disinfecting liquid can simultaneously be supplied to the individual flow paths.

Drug reconstitution systems and related methods are disclosed herein. A drug reconstitution system may include a first component in a first container in a storage state and a second component in a second container in a storage state. The first component may be selected from a group of a drug product, a diluent, a saline solution, and an IV stabilizing solution (“IVSS”). The second component may be selected from a group of the drug product, the diluent, the saline solution, and the IVSS. The first component may be different than the second component. At least one fluid path may be configured to at least selectively fluidly connect the first container and the second container. An urging assembly may be configured to selectively urge at least a portion of the first component from the first container and into contact with the second component.

A guiding sheath has a braided layer for improved deflection characteristics and ring electrodes for electrical sensing, mapping and visualization, wherein lead wires for the ring electrodes are passed through lumened tubing position under the braided layer in a proximal portion of the guiding sheath shaft and above the braided layer in a distal portion of the guiding sheath shaft. Moreover, the hemostatic valve includes an improved friction ring with air vents to reduce the risk of air being introduced into the valve.

A system for delivery of gas to a tissue, comprises: a first container containing the gas, an applicator having a distal end arranged to deliver the gas to the tissue, a second container containing a purging gas; and a flow control system for controlling flow of gas. The system also comprises a three-port valve having a first port for receiving the gas from the first container, a second port for receiving the purging gas from the second container, and a third port in fluid communication with the applicator. The valve is switchable between a first state at which the first port fluidly connects to the third port, and a second state at which the second port fluidly connects to the third port.

A method for performing a medical procedure requiring effective, reliable and foolproof delivery of controlled amounts of a medical grade gas to a patient includes providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams. The method also includes connecting the compressed gas cylinder to an integrated compressed gas unit including a regulator valve assembly positioned between an outlet port and an inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. A flow control system is secured to the compressed gas unit and the medical grade gas is delivered in precisely controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas to vasculature of the patient.

A non-surgical method of delivering a liquid radioactive solution from a source to a recipient comprising the steps of: determining a desired recipient level of radioactivity and recipient volume of the radioactive solution to be delivered to the recipient, providing a first valve having a waste position and a recipient position, providing a bolus conduit, a waste conduit and a recipient conduit, each conduit having a valve end being connected to said first valve, so that the first valve can establish a waste flow path in the waste position and a recipient flow path in the recipient position, the recipient flow path being different from said waste flow path, the bolus conduit comprising a measuring section and an internal volume, the internal volume being approximately equal to the desired recipient volume of the radioactive solution to be delivered to the recipient, arranging said first valve in the waste position, transporting a first amount of said radioactive solution through said waste flow path, the first amount of said radioactive solution having an initial level of radioactivity that is at least approximately equal to or higher than the desired recipient level of radioactivity and an initial volume that is larger than the internal volume of said bolus conduit, providing a radiation detector, the radiation detector being operable to measure a level of radioactivity of the radioactive solution in said measuring section, measuring a reference level of radioactivity of said radioactive solution present in said measuring section, wherein when the reference level of radioactivity is approximately equal to an injection level of radioactivity, the method further comprises the steps of: arranging the first valve in the recipient position, and transporting the radioactive solution present in the bolus conduit through the recipient flow path.

Systems, methods, and devices are described for providing a brace having an inflation control. The control directs fluid flow from an inflation component to one or more inflatable cells of the brace. The inflatable cells are independently inflated and deflated by the inflation component through the control. The control allows a user to create a fluid path between the inflation component and one of the inflatable cells by positioning the control in an orientation corresponding to the desired inflatable cells. Each inflatable cell is independently inflated and deflated in various orientations of the control.
