    摘要: The invention relates to the guidance, positioning and placement confirmation of intravascular devices, such as catheters, stylets, guidewires and other flexible elongate bodies that are typically inserted percutaneously into the venous or arterial vasculature. Currently these goals are achieved using x-ray imaging and in some cases ultrasound imaging. This invention provides a method to substantially reduce the need for imaging related to placing an intravascular catheter or other device. Reduced imaging needs also reduce the amount of radiation that patients are subjected to, reduce the time required for the procedure, and decrease the cost of the procedure by reducing the time needed in the radiology department. An aspect of the invention includes, for example, an endovenous access and guidance system. The system comprises: an elongate flexible member adapted and configured to access the venous vasculature of a patient; a sensor disposed at a distal end of the elongate flexible member and configured to provide in vivo non-image based ultrasound information of the venous vasculature of the patient; a processor configured to receive and process in vivo non-image based ultrasound information of the venous vasculature of the patient provided by the sensor and to provide position information regarding the position of the distal end of the elongate flexible member within the venous vasculature of the patient; and an output device adapted to output the position information from the processor.

    摘要: A Graphical User Interface (GUI) for an ultrasound system. The ultrasound system has operational modes and the GUI has corresponding icons, tabs, and menu items image and information fields. The User Interface (UI) provides several types of graphical elements with intelligent behavior, such as being context sensitive and adaptive, called active objects, for example, tabs, menus, icons, windows of user interaction and data display and an alphanumeric keyboard. In addition the UI may also be voice activated. The UI further provides for a touchscreen for direct selection of displayed active objects. In an embodiment, the UI is for a medical ultrasound handheld imaging instrument. The UI provides a limited set of hard and soft keys with adaptive functionality that can be used with only one hand and potentially with only one thumb.

    摘要: According to the invention, an object in an ultrasound image is characterized by considering various in-vivo object parameters and their variability within the ultrasonic imaging data. Specifically, it is assumed that the object may be defined in terms of statistical properties (or object identifying parameters), which are consistently different from properties of the environment. Such properties are referred to as the object's signature. The statistical properties are calculated at selected locations within the image to determine if they fall within a predetermined range of values which represents the object. If within the range, the locations are marked to indicate they are positioned within the object. A border may then be drawn around the object and the area calculated.

    摘要: In an intravascular ultrasonic (IVUS) imaging system ring-down artifact is reduced or eliminated by dynamically enhancing the ring-down over a plurality of scans, determining the ring-down range by keying on a ring-down-to-blood transition characterized by a rapid change from high amplitude to low amplitude echoes, and using a spectral pattern for a single or several A-scans within the ring-down range, using for example an FFT analysis, as the basis of selectively filtering current or subsequent images using the recently computed ring-down pattern.

    摘要: Devices and methods for fistula-free vascular access for hemodialysis are disclosed. In exemplary embodiments, devices are provided comprising a transcutaneous access port (200) for needlelessly connecting a patient to a dialyzer, said port having different inner lumen profiles for arterial or venous blood flow and further comprising an intracorporeal conduit providing a fluid path between said transcutaneous port and a blood vessel, wherein said conduit has a distal more rigid segment attached to a device anchor (400), said device anchor having distal and proximal self-expandable segments for anastomosing said conduit to a blood vessel. An exemplary fistula-free hemodialysis method (100) provided herein consists of percutaneously deploying a first intracorporeal conduit in an artery and a second intracorporeal conduit in a vein and independently connecting each of said conduits to the arterial and venous lines of a dialyzer using said transcutaneous access ports.
