摘要： Medical catheterization is carried out by introducing a catheter into a heart, sliding the catheter through a sheath that encloses a multi-electrode probe into a chamber of the heart. The sheath is retracted to expose the probe. As the sheath is retracted the exposed probe expands into a spiral configuration, and the electrodes contact the endocardial surface of the chamber at multiple contact points.

摘要： The subject of this disclosure includes an apparatus for visually supporting a tissue ablation procedure, including a display comprising a user interface; and at least one processor in communication with the display, the at least one processor configured to control one or more of a plurality of electrodes of a radiofrequency balloon catheter to ablate organ tissues of one or more targeted pulmonary veins; determine a characteristic, based on ablation parameters of the radiofrequency balloon catheter, of pulmonary vein isolation (PVI) success rate; and present, on the display, visual information corresponding to each electrode for an indication, based on the characteristic, for PVI success rate.

摘要： A contact force sensor is constructed using a spring in which a resilient member is interposed between two contacting elements. Extensions connected to the resilient member are in contact with the elements. A force applied to at least one of the elements causes a deformation of the spring that correlates with a displacement of the elements relative to one another.

摘要： A balloon catheter includes a shaft, a balloon including an expandable membrane, one or more ablation elements, and one or more passages via the expandable membrane. The shaft is configured for insertion into an organ of a patient. The balloon is fitted at a distal end of the shaft. The one or more ablation elements are disposed over the expandable membrane and are configured for tissue ablation. The one or more passages via the expandable membrane are configured to allow blood to flow between a distal end and a proximal end of the balloon, while the balloon is in an expanded configuration.

摘要： A catheter is made by coextruding first and second molten polymers, wherein the second molten polymer forms a flexible inner core and the first molten polymer forms exactly two bands on opposite sides of the inner core. The inner core is braided, and a third molten polymer extruded onto the braid to form a flexible jacket that encloses the braid, the bands and the inner core. The bands are more rigid than the inner core, and they provide preferential in-plane bending.

摘要： A manufacturing method includes providing a flat sheet perforated with holes, which have respective initial shapes and respective axes of symmetry. The axes of symmetry of the holes point toward a common origin within the flat sheet. The perforated flat sheet is deep-drawn into a cylindrical shell using a punch centered about the common origin, including deforming the holes from the initial shapes into respective predefined final shapes having different aspect ratios relative to the initial shapes.

摘要： A catheter includes an insertion tube, a flexible substrate and one or more electrical devices. The insertion tube is configured for insertion into a patient body. The flexible substrate is configured to wrap around a distal end of the insertion tube and includes electrical interconnections. The electrical devices are coupled to the flexible substrate and are connected to the electrical interconnections.

摘要： Cardiac catheterization is conducted using a probe having a balloon assembly, in which a spring has a resting axially elongated configuration and a torsed, axially shortened configuration. An inflatable balloon is twisted about the spring and mechanically linked to the spring. A flexible sheath is disposed about the spring within the balloon, the sheath and the wall of the balloon defining a chamber to contain a fluid flowing therein and thereout for inflation of the balloon and deflation of the balloon so as to energize and de-energize the spring.
