Abstract: The present disclosure relates to a devices and methods to control suction during medical procedures, and more particularly to medical suction devices, systems, and methods for controlling suction using the portable suction devices/systems during endoscopic procedures. For example, the present disclosure includes a portable suction device in fluid communication with an endoscope system, the portable suction device including: a suction regulator device releasably coupled to and in communication with at least one suction tube of the endoscope system, the at least one suction tube in fluid communication with an endoscope of the endoscope system and a suction source of the endoscope system, wherein the suction regulator device is actuatable to at least one of increase or decrease a suction force within the at least one suction tube.

Abstract: The present disclosure relates to methods of performing ureteroscopy, a ureteroscope for insertion into a ureter or an access sheath, and systems related thereto. In embodiments, the present disclosure includes an endoscope, for insertion into a ureter or an access sheath, the endoscope including: a shaft including: a first end, a second end positioned axial opposite of the first end, a working channel extending axially through the shaft, between the first end and the second end, and at least one protrusion extending at least one of: from an exterior surface of the shaft, or into the working channel; and a handpiece releasably coupled to the shaft adjacent the first end.

Abstract: An improved electrical pulse generator incorporating MOSFET components, a programmable high voltage power supply, and a shaping network for generating short duration signals having narrow pulse widths and short rise times.

Abstract: A computer graphical user interface (GUI) for multi-dimensional analysis of objects by manipulating discovered semantic properties. A computer system robotically builds a semantic model of information contained on an information retrieval system such as the Internet. The semantic model is stored as metadata in an intermediate format on the computer system. The computer system performs a semantic analysis on the metadata and generates search results in response to user queries. The GUI allows a user to select resource metadata and accumulate the metadata into a query definition. The GUI dynamically extracts metadata from user-selected query results and displays the results grouped by types or categories of metadata. The query results may be also displayed on screen in a sidebar. A user may pin metadata items and display changes to the query results based upon the pinned items.
