摘要： The trapping balloon catheter includes a catheter shaft formed to predetermined total length L from a rear end connected to a hub to a tip. A balloon is provided in a tip region of the catheter shaft and urges and fixes a guide wire to an inner peripheral surface of a guiding catheter by being expanded in a lumen of the guiding catheter. A stopper is provided on an outer peripheral surface of the catheter shaft and is capable of adjusting a length (effective length) in which the trapping balloon catheter is inserted into the lumen of the guiding catheter, by changing a locking position.

摘要： A method of performing a neurovascular procedure includes providing an assembly including a guidewire having a guidewire hub, an access catheter having an access catheter hub, and a guide catheter having a guide catheter hub. The method includes coupling the guidewire hub to a first hub adapter, coupling the access catheter hub to a second hub adapter, and coupling the guide catheter hub to a third hub adapter. Each of the first hub adapter, the second hub adapter and the third hub adapter is movably carried by a support table. The method includes driving the assembly in response to movement of each of the first hub adapter, the second hub adapter and the third hub adapter along the support table until the assembly is positioned to achieve supra-aortic vessel access.

摘要： A method for displaying guidance information during an image-guided surgical procedure comprises receiving, by one or more hardware processors, data from a tracking system associated with an elongate device comprising a flexible body and calculating, by the one or more hardware processors, at least one condition along a length of the flexible body based on the data. The method further comprises determining, by the one or more hardware processors, supplemental guidance information based on the at least one condition and augmenting, by the one or more hardware processors, one or more images with the supplemental guidance information to produce one or more augmented images. The method further comprises displaying the one or more augmented images on a display device at a surgeon console.

摘要： Methods, apparatus and computer software products implement embodiments of the present invention that include applying energy to a probe that is in contact with tissue in a body cavity so as to ablate the tissue. While applying the energy, signals are received from a location transducer in the probe, which are indicative of a location of the probe in the cavity. The signals are processed so as to derive 3D location coordinate points corresponding to the location of the probe at a sequence of times during which the energy was applied. While applying the energy, a 3D representation of the body cavity is rendered to a display, and visual indicators are superimposed on the 3D representation, the visual indicators corresponding to the 3D location coordinate points at the sequence of times. Finally, a linear trace connecting the coordinate points in accordance with the sequence is superimposed on the 3D representation.

摘要： Devices and methods for vascular navigation, assessment and/or diagnosis are described which determine the location of the tip of a vascular catheter using the introduction of a medium with a measurable parameter (e.g., temperature, light reflection, sound reflection, etc.) and sensing and measuring the measurable parameter as the catheter is advanced. Measurements of the parameter are tracked over time, recorded and analyzed. The value of the parameter and/or the shape of the parameter value vs. time curve may be used in the analysis. For example, curve amplitude, variability, standard deviation, slope, etc. may be used in the analysis of catheter location.

摘要： A catheter system for treating site within or adjacent to a vessel wall or a heart valve includes a light source, a first and second light guide, and an optical alignment system. The light source generates light energy. The first and second light guides receive the light energy from the light source and have respective guide proximal ends. A multiplexer directs the light energy toward the guide proximal ends of the first and second light guides. The optical alignment system determines an alignment of the light energy relative to at least one of the guide proximal ends and adjusts the positioning of the light energy relative to the at least one of the guide proximal ends based at least partially on the alignment of the light energy relative to the at least one of the guide proximal ends.

摘要： In some embodiments, data sensed and/or operational parameters used during a catheterization procedure are used in the motion frame-rate updating and visual rendering of a simulated organ geometry. The organ geometry is rendered as a virtual material using a software environment (preferably a graphical game engine) which applies simulated optical laws to material appearance parameters affecting the virtual material's visual appearance, as part of simulating a scene comprising the simulated organ geometry, and optionally also comprising simulated views of a catheter probe used for sensing and/or treatment. Optionally, measurements of and/or effects on tissue by sensing and/or commanded probe-tissue interactions are converted into material appearance changes, allowing dynamic visual simulation of intra-body states and/or events based on optionally non-visual input data. In some embodiments, physiology, motion physics, and/or other physical processes are simulated based on live inputs as part of associating material appearance properties to the simulated tissue's geometry.

摘要： A system includes an expandable distal-end assembly, a proximal position sensor, a distal position sensor, and a processor. The expandable distal-end assembly is coupled to a distal end of a shaft for insertion into a cavity of an organ of a patient. The proximal and distal position sensors are located at a proximal end and a distal end of the distal-end assembly, respectively. The processor is configured to estimate a position and a longitudinal direction of the proximal sensor, and a position of the distal sensor, all in a coordinate system used by the processor. The processor is further configured to project the estimated position of the distal sensor on an axis defined by the estimated longitudinal direction, and calculate an elongation of the distal-end assembly by calculating a distance between the estimated position of the proximal sensor and the projected position of the distal sensor.
