Abstract: In some examples, a catheter includes an expandable member configured to expand radially outward from a collapsed configuration to an expanded configuration. The expandable member is configured to be expanded and contracted in a controlled manner, e.g., in response to user actuation or automatically under the control of control circuitry of a device. For example, in some examples, control circuitry of a device can be configured to control the expandable member to expand and contract according to a predetermined expansion frequency or according to an expansion frequency determined based on a cardiac cycle of a patient.

Abstract: A water jet system may be used for performing surgery. The water jet system includes a water jet device to provide a water jet flow to break apart tissue in an enclosed operative site. The water jet system includes an aspiration device to remove material from the enclosed operative site. The water jet system includes a control system with an aspiration pump coupled to the aspiration device and to draw material through the aspiration device. The control system includes an aspiration flow rate meter to measure an aspiration flow rate through the aspiration pump. The control system includes a controller to control operation of the aspiration pump based at least in part on feedback from the aspiration flow meter. The control system is configured to provide a targeted aspiration flow.

Abstract: A method for controlling an orientation of a steerable distal portion of an elongate instrument, said instrument comprising at least one tensioning member attached to said steerable distal portion may include receiving an input command at a controller for articulation of said steerable distal portion, the articulation correlating to an approximate y-bend and an approximate x-bend of said steerable distal portion; calculating an approximate overall bend from said approximate y-bend and said approximate x-bend; and setting a limit of said approximate overall bend beyond which said steerable distal portion is not permitted to achieve. The method may further include one of: causing actuation of said at least one tensioning member to achieve said y-bend and said x-bend on a condition of said calculated approximate overall bend being equal to or less than said limit, and repeating the receiving, calculating, and setting steps on a condition of said calculated approximate overall bend being greater than said limit.

Abstract: The present invention relates, generally, to reporting the approximate three-dimensional orientation of the steerable distal portion of an endoscope to the user of the endoscope. More particularly, the present invention relates to a system and method for providing the endoscope-user a display from which to more easily determine the approximate three-dimensional orientation of the steerable distal portion of the endoscope, thereby facilitating navigation of the endoscope. The present invention also relates to a system and method for limiting the amount the steerable distal portion can bend overall to reduce or eliminate the user's ability to over-retroflex the steerable distal portion of the endoscope.

Abstract: A system for graphically visualizing an orientation of a steerable distal portion of an elongate instrument is disclosed. The system includes an instrument having an elongate body. The elongate body includes a proximal portion and a steerable distal portion. The system also includes at least one tensioning member attached to said steerable distal portion, wherein the actuation of said at least one tensioning member results in an approximate y-bend and an approximate x-bend of said steerable distal portion, and wherein said approximate y-bend and approximate x-bend define an approximate overall bend of said steerable distal portion. The system further includes a graphical user interface and an icon representing said approximate overall bend on said graphical user interface.

Abstract: Medical and/or robotic devices, systems and methods can provide an indicator associated with each manipulator assembly of a multi-arm telerobotic or telesurgical system.
