摘要： A disposable single-piston dual-action reciprocating pump part includes a single piston, an output port, and a balloon damper. The output port is configured for outputting fluid pumped by the single piston. The balloon damper is fitted in the output port, and the balloon damper is configured to suppress a pulsation in a flow rate of the outputted fluid.

摘要： A system includes two or more pairs of electrodes and a processor. The electrodes are disposed over a distal end of a catheter for insertion into a heart of a patient. The electrodes in each pair are parallel with one another, and the pairs are not parallel with one another. The processor is configured to receive electrophysiological (EP) signals acquired by the pairs of electrodes, and, based on a timing of the received EP signals, calculate a local direction at which the received EP signals propagate in the heart.

摘要： A pump device includes a rotary motor, a compartment for insertion of a disposable pump part, and one or more pulsation-reduction elements. The disposable pump part includes an input port, an output port, and a dual-action reciprocating assembly. The input port is configured for intaking fluid. The output port is configured for outputting the fluid. The dual-action reciprocating assembly is configured for pumping the fluid. The assembly includes a single piston and a rod configured to be coupled to the rotary motor, so as to drive the piston. The one or more pulsation-reduction elements are configured to reduce a pulsation in the outputted fluid, caused by the single-piston dual-action reciprocating assembly.

摘要： In one embodiment, a system includes a catheter including an insertion tube and a first position sensor, a pusher including a second position sensor, and an expandable assembly including flexible strips disposed circumferentially around a distal portion of the pusher, with first ends of the strips connected to the distal end of the insertion tube and second ends of the strips connected to the distal portion of the pusher, the flexible strips bowing radially outward when the pusher is retracted, processing circuitry to receive a respective position signal from the first and second position sensors, compute location and orientation coordinates for the position sensors subject to a constraint that the position sensors are coaxial and have a same orientation, compute a distance between the computed location coordinates of the position sensors, and find position coordinates of the flexible strips responsively to at least the computed distance.

摘要： A method includes receiving a target location for performing a procedure in an organ of a patient and a mapping of a lumen located along a path to the target location. Based on the target location and the mapping received, the method further includes producing an endoscopic view of at least the lumen and displaying in the endoscopic view, on at least a wall of the lumen, one or more marks indicative of a progress of the procedure.

摘要： A method includes collecting a plurality of bipolar electrograms and respective unipolar electrograms of patients, the electrograms including annotations in which one or more human reviewers have identified and marked a window-of-interest and one or more activation times inside the window-of-interest. A ground truth data set is generated from the electrograms, for training at least one electrogram-preprocessing step of a Machine Learning (ML) algorithm. The ML algorithm is applied to the electrograms, to at least train the at least one electrogram-preprocessing step, so as to detect an occurrence of an activation in a given bipolar electrogram within the window-of-interest.

摘要： Described embodiments include an apparatus that includes an intrabody probe and an electrode coupled to a distal end of the intrabody probe. The electrode includes a flexible electrically-insulating substrate, comprising a substrate surface. The electrode further includes a layer of an electrically-conducting metal covering at least part of the substrate surface. The electrode further includes a metallic sheet, comprising an inner sheet surface, and an outer sheet surface shaped to define multiple depressions. The electrode further includes an adhesive, which fills the depressions and bonds the outer sheet surface to the layer of the electrically-conducting metal. Other embodiments are also described.
