Abstract: Point-of-sale systems may include stations having interactive monitors mounted at specific heights and angles that permit such monitors to be viewed and interacted with by an associate or a customer. Some point-of-sale systems may include two stations, each having a monitor aligned in opposite directions, a user of one monitor may not view the other monitor, and vice versa. The point-of-sale systems may also include instrument readers (e.g., credit card readers or NFC readers) for recognizing payment instruments of customers and identifying the customers based on the payment instruments. Each of the monitors and instrument readers may be linked by cables to computer devices that are securely housed in a chamber above which the monitors are mounted. The monitors and other components are installed in a modular fashion, and may be independently installed or replaced without requiring an installation or replacement of the entire point-of-sale system.

Abstract: Interventional catheter assemblies and components providing improved operational control of interventional catheters and/or operating heads of interventional catheters are provided. In general, controllers incorporate at least two operator selectable control features for controlling operation of the interventional catheter and/or an operating head, and are housed independently of the interventional catheter operating systems and other control systems, which may be provided in a housing located or locatable at a proximal region of the interventional catheter. The controller may be both dockable in and removable from the housing, and is operable in both a docked condition and a removed condition, providing flexibility and mobility in operational control during an interventional procedure.
